DLT – Data ‐logger and data transfer unit. Power supply 24 Vdc ‐ Fanless – Diskless ‐ DIN rail mounting

P r o d u c t o v e r v i e w

The DLT is a compact embedded PC, for Din rail mounting. Thanks to the used low power consumption CPU processor without active cooling, DLT is particularly suited for applications where reliability and performances are major requirements. The processor is scalable: this grants long life applications. Total connectivity is guaranteed by the huge amount of communication interfaces like 2 serial channels, selectable as RS-232/422/485, 10/100 Mbit/s Ethernet and 2 USB ports. The integrated video controller operates as standard VGA (CRT monitor as well as LCD panels…).

LCD ‐1H & LCD ‐ 3H Snow switch

F e a t u r e s & A d v a n t a g e s

Minimum energy costs Automatic snow melting Snow melt only when necessary Sense both temperature and precipitation Performance optimized for hydronic

applications Simple installation Reliable Low cost

D e s c r i p t i o n

LCD-1H & LCD- The LCD–1H & 3H Snow Switch saves energy by providing snow melting only when required during snowfall and for a time thereafter to ensure complete melting.

As heavy, wet spring and autumn snow often occurs above freezing, the LCD–1H & LCD–3H detects precipitation as snow at temperatures below 38°F (3.3°C). The LCD–1H's internal, isolated 3 amp relay contact remains closed for a 5-hour hold-on time after snowfall stops to ensure complete snow melting and pavement drying. The LCD–3H remains closed for 1-hour hold-on time.

The LCD–1H & 3H Snow Switch achieves high performance at low cost through microprocessor control. Members of the LCD product family have provided more than 70 million hours of reliable snow melting control.

For complete information describing application, installation and features, please contact Customer Service or check on the web at www.networketi.com.

Installation The LCD–1H Snow Switch housing has one 1/2” (16mm) NPT threaded opening. Choose an unobstructed elevated location exposed to snowfall. Rigidly mount in upright, plumb position as shown. Connect the black and white wires to the 24 VAC power supply. Yellow wires are from an isolated 3 Amp resistive/1 Amp inductive relay contact.

GSM/GPRS The modem handles data speeds between 300 and 115 200 Bps and has a full serial RS 232-port. The unit can be configured with standard AT commands and a user friendly PC-programme.

The GSM-module is a Siemens Tri-band modem with GPRS Class 10.

CPU The unit is equipped with a microprocessor which can store software for various applications.

Inputs Two alarm inputs generate text messages to pre-defined mobile numbers when triggered. Messages can be sent both when an input goes “high” and “low” i.e. when voltage is applied and when voltage is removed from the input.

Output A grounding output, activated via SMS or call, can be used to control equipment or an external relay. (A cabling with an external alternating relay is available as an option).

Customs Code 85389099

Access control If activated, access list functions in the unit will monitor whether an incoming call/SMS or data call is authorised to communicate with the Multimodem V3.

Up to 100 numbers can be stored in the access list.

On-line affirmation The on-line affirmation feature will update the GSM-module on the network at regular intervals. This will ensure that the module is on-line with the GSM network at all times.

The unit can at the same time, via dial-up and CID, confirm to a monitoring software that it is operating. The “alive” feature is free of charge.

Applications The Multimodem is suitable to connect to machines with a serial communication interface and/or for monitoring of passive sensors and alarm transmission via SMS.

The unit works as a regular GSM/GPRS modem, it is however adapted for industrial use and has a very high level of reliability, not attainable with a normal GSM modem.

Configuration The Multimodem is easily configured with the free pc-programme Configuration Tool. Templates of settings can be saved for similar installations or as a customer log.

Antenna placement is easily optimized using the programme’s signal strength indicator, ideal to ensure reliable operation.

Battery back-up An integrated, charge controlled, back-up battery is availabe as an option. The unit will send SMS if external power (230V) fails and when it returns if this option is installed.

CONTROL – Hygrostat‐ HY‐WE

The Hygrostat “HY/WE” is an electromechanical regulator for relative humidity. The hygrostat does not require any power supply. The switch contact can be directly used for control of electric loads.

The switch point setting (10% to 80 % rH) is done by a rotary switch.

At the end position, the switch is always closed or open, independent of the air humidity value.

T y p i c a l A r e a s o f A p p l i c a t i o n

• Supervision of storage spaces, in the foodstuff sector, quality assurance or in air-conditioning systems

• Humidity measurement systems for customer specific projects, micro-controller applications, under Windows or Linux

W i n d o w s ‐ S o f t w a r e

• Display of humidity and temperature data • Calculation and display of dew-point, absolute

humidity, vapour pressure, saturation pressure and enthalpy

• Tabular presentation of measurement data • Saving of data to a hard disk

D e s c r i p t i o n

This product provides a powerful system for measuring and recording temperature and relative air humidity. The compact sensor has the external dimensions Ø12 x 150 mm and is housed in an enclosure of high-grade steel. The interface converter included allows working directly from the PC or directly with customer-specific controlling and regulating systems.

The front end containing the sensors is protected by a polyethylene sinter filter against water splashes and mechanical damage. The temperature sensor used is a precision NTC. Humidity is measured using a capacitative polymer sensor that will remain stable over a long time.

The micro-controller on the interface converter compensates for any linearity error and temperature drift of the sensor element. The mathematical operations used guarantee excellent measuring accuracy and long-term stability, even under extreme operating conditions.


BILD

The current measurement data is input as an ASCII string into the connected computer via the serial interface (RS 232 compatible). By means of the PC, the measurement data is recorded and displayed as a graphic. An easy-to-use Windows program for displaying and saving measurement data is included.
