    Horn Relay Board

    These relay boards are designed to control 3 or 4 relays from one of our hand throttles. Often used for lights and horns on model locomotives they can be used in many other applications. The circuit allows control of either 3 or 4 relays with only 2 or 3 wires. It also has a number of "break points" on the circuit board that gives it a lot of flexibility to be used with [e.g. sound] systems that require isolated switch inputs.
