PSR1230A Pump Sequence Controller 230VAC

PSR1230A Pump Sequence Relay - Three Circuits 230VAC

11 pin plug-in - Suitable Bases - 90.21 11pin Base

Pump sequence module is designed to optimize the wear on pumps, compressors or generators. The first input energizes the first pump and stores this in non-volatile memory. Subsequent inputs will energize the next output. The number of its outputs correspond to the number of outputs. After power down or no inputs activated and an input is activated, the next in the sequence of outputs is activated. This ensures balanced usesage of the pumps because the same pump is not activated at the beginning of a sequence.

Features:

• Three normally open pump outputs
• Permanent memory for next pump activated after power off
• Three normally open pressure switch inputs (voltage free)
