LX-IVM Compatible Pump Start Relay

Specifically designed to work with the Rain Bird LX-IVM Controller

The Rain Bird line of pump start relays work with a lawn controller’s start/stop command to facilitate the electrical path from the breaker box to the pump motor. Rain Bird PSR110/220-IVM models are specifically designed to work with the Rain Bird LX-IVM Controller through the use of a 9 volt latching relay. This provides “pilot duty” operation for all types of electrically driven pump equipment.
