The Monitor Sensors Rainfall Sentry Pump Controller monitors the rainfall and operates an alarm relay when a programmable amount of rain falls within a programmable period of time. The relay is released after a second programmable period of time has elapsed. This second period of time may be extended, if desired, by further rainfall. The operator may also program the amount of this additional rain, and the extended time period. A SPDT 1 Amp  relay provides volatge free contacts to operate external equipment. An external heavy duty relay or contactor is required to control a pump motor.
