The cooling controller ST121-KD1KAR.112 with two sensor inputs and five keys is used for the thermostatic temperature control of refrigerating plants. It is supplied with 230V AC and has two exit relays. The functions of the outputs and special keys can be freely selected, thus various applications with only one controller are possible. The controller, for example, can operate with two coolers if the evaporator sensor is parametered as sensor for a second refrigerating chamber.
Networking of the controller takes place via the ST-Bus interface. 900323.001
