Single display controller Microprocessor controller, format 48x48 (1/16 DIN) manufactured using SMT.

This instruments provides a complete operator interface, protected by a Lexan® membrane that ensures level IP65 faceplate protection.

The 400 model has 4 keys, 4 digits display, and 2 indicating LED's 3 indicating LED's
For 401 model a further 3 LED's bar-graph.

The main input for the process variable is universal and provides the possibility to connect many types of input sensor:

Thermistor PTC
Thermocouple type J, K, R, S, T, B, E, N
Resistance thermometer PT100 3-wires
Linear inputs 0...60mV, 12...60mV, 0...20mA, 4...20mA, 0...10V, 2...10V

The type of input is selected from the faceplate keys and no external adapter or shunts are necessary.

Model 401 can have an auxiliary input for a 50mAac current transformer to monitor the load current.

It is also possible to set an alarm point related to the current transformer input in order to check eventual load malfunction.

Both instruments have 2 (3 for 401 model) relay (5A/250Vac, cosφ=1) or static (10Vdc/30mA) outputs with Heat, Cool or Heat/Cool not overlapping and/or alarm function.

All the programming procedures of the instruments are facilitated by the grouping of the parameters in function blocks (CFG for the control parameters, “Inp” for the inputs, “Out” for the outputs, etc.) and by the possibility of selecting a simplified menu for entering the most frequently used parameters.

To simplify the configuration even further, a programming kit is available for PC, which includes a menu driven configuration program for Windows and the necessary cable to connect the instrument.

Password protection can be used to restrict the levels of editing and displaying the configuration parameters.
