2 Channel RF Relay | 2km Range

A simple 2 channel RF module with up to 2km range. This module is designed for remote switching of loads triggered from a simple relay input. A common application is to have one end connected to a sensor or switch, with the other end controlling a contactor. Since the unit is bi-directional, it can have 2 channels of input or output from either end. The unit is pre-configured and requires no programming. It operates on the 433MHz range which is Australia compliant. This unit requires a 12V power supply at either end and may require an antenna depending on the site conditions.
