Switch two relays on and off with an R/C system or servo controller! Normally open and normally closed solder points are provided for each relay. You can drive two independent motors, contactors or pneumatic/hydraulic solenoids. Plus a simple wiring configuration also converts this to a mechanical H-bridge which is perfect for running a single linear actuator or motor in both forward/off/reverse. When used with one of our actuators, optional inputs from limit switches permit you to arrest motion in either direction. The silver cadmium oxide relay contacts offer you a maximum motor/coil load of 12 amps at 30 VDC (inductive). Fault detection safely switches off both relays if receiver signal is lost.
