The PC-105 is a 5-channel pump controller designed to handle multiple pump applications. Alternatively, it can operate as a 5-channel switch.
The PC-105’s control functions support all of the popular industrystandard 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.
