400 Data Sheet

Profile:

Full featured microprocessor based temperature controller in 1/16 DIN (48x48) format manufactured using SMT. The instruments provides a complete operator interface, protected by a Lexan® membrane that ensures level IP65 faceplate protection. The controllers have 4 keys, 4 digit displays, 2 indicating LED's for 400 model and 3 indicating LED's for 401 model. Additionally the controllers have an innovative but simple indicator of variation from the set point using just three colour coded LED's, green for OK, red for a mismatch. This makes it easy for an operator to see at a glance that conditions are within acceptable limits.

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

• Thermocouple type J, K, R, S, T, B, E, N
• Resistance thermometer PT100 3-wires
• PTC Thermistor
• 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 shunts or adapter are required. 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. The instruments have 2 (3 for 401 model) relay (5A/250Vac, cosj=1) or static (10Vdc/30mA) outputs with Heat, Cool or Heat/Cool 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 (see technical data cod. 80021).

A configurable personal software protection code (password protection) can be used to restrict the levels of editing and displaying the configuration parameters.
