This product consists of a single-pole, double-throw (SPDT) power relay and a control circuit that measures incoming radio control (RC) signals, making it easy to control large, electrically isolated loads in RC systems. Example applications include using extra channels on an RC receiver or servo controller to turn on lights, motors, or irrigation valves.
The RC switch measures the width of incoming RC pulses and compares it to a user-configurable threshold (with 64 s of hysteresis) to decide whether to activate the relay. By default, the threshold is approximately 1700 s, with switch activation occurring above the threshold (longer pulses), but the switch has a learning mode that allows you to change the threshold and the activation direction. A safe-start feature reduces the likelihood of unexpected activation.
