The micro-processed controller ST501-KC1KAR.112 is used for the thermostatic temperature control of simple refrigerating plants. It is supplied with 230V AC and has two exit relays. The relays can be used for different functions, e.g. for a compressor, a fan, a defroster, an alarm relay, etc.
Two resistance sensors can be connected. One sensor seizes the refrigerating chamber temperature, and the function of the second sensor can be differently parametered.
Networking of the controller takes place via the ST-Bus interface.
