Littelfuse PC-105, 5 Channel Pump-Control Switch/

The PC-105 series is a five-channel pump controller designed to handle multiple pump applications. Alternatively, it can operate as a five-channel switch. The PC-105’s control functions support all of the popular industry standard multi-pump pump-up and pump-down configurations. It can indicate low, high, and out-of-sequence alarms and use alternating and non-alternating pump control. The non-alternating pump can be used as a jockey pump or emergency pump. Using the built-in DIP switches, individual pumps can be disabled when taken out of service for repair or maintenance.
