Relay logic Control Panels

The Relay Logic 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 contractor 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.
