Product description
The micro-processed controller ST501-KC1KAR.112 is used for the thermostatic temperature con-
trol 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 tempe-
rature, and the function of the second sensor can be differently parametered.
Networking of the controller takes place via the ST-Bus interface.
