USE
Level control relay consisting of a THR radio receiver and a transmitter.
The transmittor, placed near the reservoir and connected to a level float, transmits to the receiver the signal to fill or empty by activating or disactivating the relay. Power supply : 230Vac /9-30Vdc (possibility of accumulator or external battery).
2 logic inputs (E1 inversed, E2 standard).
