FOUR CHANNEL RELAY WITH RF IN S.A.S. NAGAR

Four channel relay board which can be controlled by a wireless remote through a wireless RF link. The relays can be used to control 240 V appliances, motors, other electronic circuits, etc. The board can operate within a range of 100m when the remote is in line of sight and around 50m when indoors. Each relay board comes with a adjustable address option which can be used to operate multiple remotes in the same area by assigning different addresses to each relay board. The remote provides 4 push switches which can be manually operated to control the relays. The input pins are also brought out to a row of header pins, which can be used to connect the remote to a microcontroller or an external circuit and control the relays through logic signals. The RF link on this board works on the 433 MHz frequency.
