The compact temperature controllers from WIKA offer display, control and monitoring of temperatures. The configuration of the sensor input is made via the multi-function input. Sensors, thermocouples and standard industrial signals, such as 4 ... 20 mA, serve as the input variable of a temperature controller. The control output can be set either as relay (for slow control), as logic level for the control of electronic solid state relays (for fast control and high current loads) or as a continuous 4 ... 20 mA output.
