Relay Logic Series™ Simplex

Single Phase Simplex

The Relay Logic Series™ Simplex control panel is simple, rugged and reliable.

The Relay Logic Series™ (RLS) Simplex control panel provides a reliable means of controlling one 120, 208, or 240V single phase pump in pump chambers, sump pump basins, irrigation systems and lift stations. 

A magnetic motor contactor is used to turn the pump on and off.  If an alarm condition occurs, an alarm switch activates the audible/visual alarm system.  Standard components are used for easy troubleshooting and service.
