Power the board
Use a fuse tap for 12V+ and the shared chassis ground. The board accepts 5 to 24V DC.
RidgeRelay is an 8-channel relay control board for vehicle accessories—ditch lights, light bars, beacons, and whatever you want within reach.
Mount the board, connect a relay to each channel, and control the rest from your phone or dash screen. The board switches each output to ground, so your accessories keep their own fused power path.
Use a fuse tap for 12V+ and the shared chassis ground. The board accepts 5 to 24V DC.
Connect each relay coil to 12V+ and its RLY terminal. Each channel sinks to ground when commanded on.
Tap a tile in the RidgeRelay app, use the on-board test buttons, or use CarPlay and Android Auto.
