This micro-processed controller serves for temperature control at high measuring accuracy. Beside resistance sensors and semiconductor thermo element the multi-sensor sensor entrance can equally process 0... 10V and/or 4...20mA. The PID regulation and/or thermostat regulation can be activated via parameter setting. Outputs are three relay contacts and an analogue output. Red LED lamps indicate the status of the output relays. The desired values and parameters determining the process are adjusted with a 4-field plastic foil keyboard.

Please note that the analogue output is not galvanically separated from the supply voltage. To avoid any problems operate the controller with a separate transformer. 900305.026
