Basic Product Types Signal Converters
– Convert one type of signal into a different type• Analog signals• Digital signals• Communications
Signal Isolators– Electrically isolate an output signal from an input
• Protects input circuits from damage
Special Function Modules– Perform various functions– DIN rail mounted
Fundamentals, contd. Digital signals
– Frequency (speed) of pulses varies as measurement varies
– Typical digital sensors
Fundamentals, contd. Analog
– Voltage or current– Signal level varies as measurement varies– Typical analog sensors
Signal Converters - Analog Converters make equipment compatible Example – Analog to Analog
– PLC with 4-20 mA inputs– Sensors with varying signal outputs
Analog to Analog Products
IAMA – Universal Signal Conditioner– W/ isolation
ITMA– Thermocouple to analog
IRMA– RTD to analog
Signal Converters - DigitalExample – Frequency to Analog
– Analog input devices– Pulsed type sensors
Digital to Analog Products
IFMR– Speed Switch (Frequency to Alarm)
IFMA– Frequency to Analog Converter
Signal Converters – Analog to CommunicationsSignal to Data Communications
– Allow PCs or PLCs to monitor signal via communications
Signal to Comms. ProductsIAMS
– Analog (Volt/Current to Communications)
ITMS– TC/RTD (temperature sensors)
Signal Converters – Comms. ConvertersData to Data Communications
– Allow different devices to communicate with each other
Comms. Converter ProductsICM4
– RS232 to RS485 Converter, not-isolated
ICM5– RS232 to RS485 converter with isolation
Signal IsolationIsolators prevent ground-loopsExample
– Drive with high potential on output– PLC with non-isolated input– Most of our converters have isolation ie
ICM5
