1.2 Terms and definitions Analog quality – A
Analog quality refers to the constantly changing voltage, current, temperature, speed, pressure, and flow.
For instance, temperature is constantly changing over time as seen in the following figure. The changing temperature can be treated as a digital value in the PLC by using resistance temperature detector (RTD) input module.
Digital quality – D Digital quality refers to discrete changes in voltage, current, temperature, velocity, pressure, and flow over a period of time as illustrated in the following figure. For instance, ON/OFF signal is represented as digital quality of 0 and 1.
1. Introduction 1.2. Terms and definitions
R200 Isolated Thermocouple Input Module TC4S User's Guide 15 September 2010 Honeywell
The CPU module does not directly accept analog values. Therefore, analog value is converted into a digital value before feeding to the CPU. In addition, the digital values from the CPU must be converted back into analog values to provide an analog output.
Thermocouple sensor A thermocouple is a sensor for measuring temperature. It consists of two dissimilar metals, joined together at one end. When the junction of the two metals is heated or cooled a voltage is produced that can be correlated back to the temperature. The thermocouple alloys are commonly available as wire.
Disconnection detection When a part of a compensating cable or thermocouple is disconnected, the Isolated Thermocouple Input module detects the disconnection.
Compensating cable Cable to compensate the tolerance due to the distance between input thermocouple terminal and thermocouple input module (temperature change) and in which both terminals have similar thermo electromotive force between 90 and 150°C.
Thermo electromotive force Thermo electromotive force for thermocouple temperature has non-linear characteristics. Therefore, it processes the non-linear characteristics to linear in the module.
Reference junction compensation (RJC) In a thermocouple sensor, the thermo electromotive force varies, depending on the temperature of a part measuring electromotive force. Since, the thermo electromotive force table of standards is based on 0°C, it compensates the gap between the current temperature and the actual reference temperature (0°C).

ATTENTION
• A thermocouple sensor measures temperature by using fine voltage (electromotive force), which is generated when applying temperature Rate Change to a junction between two different metals.
• The temperature-electromotive force relation specification of normal thermocouple sensor provides the electromotive force, which is measured when a sensor’s measuring point is at 0°C. When temperature is measured using a thermocouple sensor, cold junction compensation (reference junction compensation, RJC) is used (built-in function of temperature measuring module).
Temperature conversion characteristics
The isolated thermocouple input module converts the thermocouple input with non-linear characteristics into A/D and yields the temperature conversion that is linearly treated.
Temperature conversion to thermocouple input has non-linear characteristics.
ATTENTION
Non-linear characteristics: regarding the relation of temperature (°) and electromotive force (µV) of a thermocouple sensor, electromotive force is different by sections even though temperature changes by a certain amount, which is called ‘non-linear characteristics.’ As seen in the above graph, the relation of temperature and electromotive force is a curve by temperature sections. The module processes the non-linear characteristics table as linear.
Conversion speed 2MLF-TC4S has the conversion speed of 40ms per channel and processes channels sequentially (operation/stop of each channel may be assigned independently).
Process time = 40ms ∗ no. of used channels
Example: If using three channels: process time = 40ms ∗ 3 = 120ms
2. Specifications 2.3. Characteristics of thermocouple temperature sensor input module
28 Isolated Thermocouple Input Module TC4S User's Guide R200 Honeywell September 2010
ATTENTION
The conversion speed of 2MLF-TC4S module is a cycle that the temperature (electromotive force) entered into terminal strip is converted into digital value and stored in internal memory.
Preciseness
The accuracy of 2MLF-TC4S module depends on the ambient temperature and is as follows:
• If the temperature measurement is 100o when the ambient temperature and K type thermocouple is used, the output range of conversion data is between 100 o - 2.6 ~ 100 o + 2.6; that is, 97.4 ~ 102.6 o.
ATTENTION
1. 2MLF-TC4S module is released from the factory after its offset/gain is adjusted by using standard source of each channel. To maintain the module’s accuracy, temporary changes to the values are strictly prohibited.
2. 2MLF-TC4S module has different errors within temperature coefficient of 100ppm, each time the operation temperature varies by one degree
2. Specifications 2.3. Characteristics of thermocouple temperature sensor input module
R200 Isolated Thermocouple Input Module TC4S User's Guide 29 September 2010 Honeywell
Temperature display 2MLF-TC4S module displays temperature down to one decimal point.
a) If it displays 123.4o
b) If it displays 100
by converting, the value stored in the internal memory is 1234. In addition, it may display temperature by Celsius or Fahrenheit, depending on the settings of 2MLF-TC4S module.
o
in Celsius, it would be 212°F by using the following formula.
ATTENTION
From Celsius to Fahrenheit degree: F=[9/5]C + 32.
From Fahrenheit to Celsius degree: C=[5/9][F-32]. Scaling function
2MLF-TC4S module has a function of scale value in user-defined range besides temperature. The scope is classified into two types: Signed and unsigned integer.
If a user selects one of the two types and sets the range, it displays the temperature through scaling operation. If scaling with signed integer is set to -250 ~ 1000 and the temperature measured E type sensor is 500.0 o, the value scaled is as follows:
2. Specifications 2.3. Characteristics of thermocouple temperature sensor input module
30 Isolated Thermocouple Input Module TC4S User's Guide R200 Honeywell September 2010
Disconnection detection function 2MLF-TC4S module measures temperature by directly connecting thermocouple temperature sensor and has the diagnosis function to detect and display any disconnection of a sensor connected.
1. In case of a disconnection between the sensors used/compensating cable and module, LED (ALM) flickers every second and generates an error code. In addition, LED (ALM) indication flickers every second even though cold junction compensating sensor installed on the module’s terminal block is separated or destructed, hindering normal connection.
2. Channel wise detection of disconnect is possible. However, it is available for only the channel(s) designated for operation. LED (ALM) is commonly used for every channel. It flickers in case even one channel is disconnected.
3. The module detects and displays disconnection and it means that the following cabling path will have partially bad connection, which requires taking measures.
Sensor connection A thermocouple sensor can either be directly connected to the terminal of the module or by using a compensating cable (type of cable depends on sensor type.) For the further information on connecting the sensor, contact sensor manufacturer.

Time average
The time average function measures temperature conversion values of a selected channel and displays the average of the total sum as a digital value.
• Setting range of average time = 320 ~ 64000ms
• Frequency of average process for a preset time can be calculated as follows:
2. Specifications 2.4. Input module function of thermocouple temperature sensor
32 Isolated Thermocouple Input Module TC4S User's Guide R200 Honeywell September 2010
Averaged frequency
It measures the temperature conversion and frequency values of a selected channel and displays the average of the total sum as a digital value.
• Setting range of average frequency = 2 ~ 64000 [times]
• Average process interval of channel used can be calculated as follows:
Moving average
It measures temperature conversion values of a selected channel per scan and displays the average of the total sum as a digital value.
2. Specifications 2.4. Input module function of thermocouple temperature sensor
R200 Isolated Thermocouple Input Module TC4S User's Guide 33 September 2010 Honeywell
• Setting range of average number = 2 ~ 100
ATTENTION
Out of the three types of averaging process, time/frequency average process does not yield temperature data for each conversion time and instead, it maintains the previous status until it reaches time/average frequency. On the other hand, in case of moving average, it yields the converted temperature, taking into account the temperature history and average for every conversion time, so it can obtain relatively faster data response than time/frequency average.
Filter function Using a filter value (corrected number) the temperature conversion setting of an assigned channel, operates and provides the output as follows:
2. Specifications 2.4. Input module function of thermocouple temperature sensor
34 Isolated Thermocouple Input Module TC4S User's Guide R200 Honeywell September 2010
• Setting range of filtering value = 160 ~ 64000ms
ATTENTION
Filtering in 2MLF-TC4S is processed using one of the averaging functions simultaneously. If you select simultaneous process, filtering is processed first and it averages and provides the temperature as a digital value. The digital data output (temperature) displays as the value gained after the final process.
Alarm function
Process alarm function
An alarm is raised if the temperature conversion value of a selected channel is higher than the temperature preset for alarm (HH, H) or lower than the temperature present for alarm (L, LL).

3. Installation and Wiring
3.1 Installation Installation environment
The isolated thermocouple input module can be reliably installed regardless of installation environment, it is essential to make note of the following before installation.
Environmental conditions
• Ensure that you install the PLC in a control panel which is waterproof and can withstand vibration.
• Ensure that the module is not exposed to direct sunlight.
• Ensure humidity level of 5 ~ 95%.
• Ensure that the ambient temperature is maintained between 0 and 55°.
Installation considerations
• Do not exert excessive force on it.
• Do not separate PCB from the case.
• Do not allow the impurities such as wiring dregs to go into the upper part of the module. Remove them if they go into the module.
• Do not attach or detach the module when it is turned ON.
3.2 Wiring Wiring precautions
1. Do not place AC power line close to the AUX signal line of the module. To avoid surge or induced noise occurring from AC, ensure adequate spacing.
2. Cable selection must take the ambient temperature and allowable current into account. The maximum size of the cable is AWG22 (0.3mm2
3. Ensure that the cable is not too close to a heating device or in direct contact with oil and similar materials. It may cause short-circuit, resulting in breakdown and malfunction of the module.

ATTENTION
Typical addressing: The following is a typical example of the addressing in the thermocouple input module. _ab_ in the variable/address refers to the number of base and slots on which the module is configured.
For instance, in case reading or writing special module variable area, 4th bit data of a module installed on #0 base and #4 slot, is expressed as follows:
R: Write only for the data for the module in MasterLogic 200 PLC.
R/W: MasterLogic 200 PLC can read and write an instruction to the module.
%U Address : The data that is usually read or written such as conversion data of special module’s internal memory in PLC CPU, which is used to read or write every time when scanning special area (regularly read data, defined in module) of special/communication module in MasterLogic 200 PLC is assigned in the area. As other devices, it is possible to directly use general instructions such as MOV, CMP, ADD, and so on (on the other hand, module’s parameter area requires PUT/GET instruction).

8. Appendix
8.1 Terminology Terms and abbreviation used in this user’s guide and the analog module in general are as described below.
• A/D converter: converts analog to digital value proportionately to the size of analog input signal.
• Analog input module: as a module with the circuit to convert analog voltage/current input signal to digital value, it has resolution of 14 and 16 bits according to converters.
• Channel: related with the terminal of analog I/O module and connected to various voltage/current I/O devices, respectively, with applicable data and diagnosis function.
• Conversion time: time necessary for analog input module to sample and convert the analog signal for the processor inside the module to get digitally-converted value input. On the other hand, it is necessary for analog output module to convert the digital value output from the processor inside the module to analog output signal so to transmit the output channel.
• D/A converter: related with the output module, it is used to change the continuous size of analog voltage and current signal proportionately to the digital value.
• Full scale: defined as the size of voltage/current where the normal operation is executed.
• Full scale error: displays the graph difference between agreeable analog-converted value and actual analog-converted value.
• Full scale range: displays the difference between the maximum and the minimum of the analog input.
• LSB (Least Significant Bit): displays the minimum value of the bit unit.
• Linearity error: analog I/O is related between continuous voltage/current value and digital value, whose agreeable I/O value is defined as a line within a distance of the minimum 1LSB of voltage/current. I/O linearity error is regarded as the declination between the agreeable-converted value and the actual-converted value on the graph.
8. Appendix 8.1. Terminology
116 Isolated Thermocouple Input Module TC4S User's Guide R200 Honeywell September 2010
• Multiplexer: a switching circuit where many signals share one A/D converter or D/A converter.
• Analog output module: a module with output circuit to convert analog DC voltage or current signal proportional to digital value delivered to the module from the processor.
• Resolution: the minimum value recognizable by a measuring instrument, which usually displays in the engineering unit (1mv) or the number of bits. In other words, 16383 types of output are available for 14 bits.
• Filter: used to reduce the change of the digitally-converted output value by sudden change of the external noise or input for the analog circuit, through two methods of Software and Hardware filters.
• Accuracy: displays the maximum declination between agreeable value and output voltage or current for the whole range of output. On the other hand, it is displays the maximum declination between agreeable value and digitally-converted input signal value for the whole range of input. Generally, percentage displays for the full scale.
• Gain, Offset and Linearity error are all included in the error type available.
• Output accuracy: displays the difference between the actual analog output voltage/current value and the agreeable-converted value on the conversion graph for the full scale, with Offset, Gain, and Drift error factors included as well as normal temperature (25°C) and available temperature range displays, respectively.
