NEW: single-loop temperature controller by GEFRAN

Overview

Microprocessor controller, format 48x48 (1/16 DIN) menufactored using SMT.

The instruments provides a complete operator interface, protected by a Lexan® membrane that ensures level IP65 faceplate protection. They have 4 keys, 4 digits display, 2 indicating LED's for 400 model, 3 indicating LED's for 401 model and 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:

Thermocouple type J, K, R, S, T, B, E, N

Resistance thermometer PT100 3-wires

Thermistor PTC

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, cosφ=1) or static (10Vdc/30mA) outputs with Heat, Cool or Heat/Cool non sovrapposto and/or alarm function.
