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 µs of hysteresis) to decide whether to activate the relay. By default, the threshold is approximately 1700 μs, 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.
Polou generally recommend using a 4- or 5-cell NiMH or NiCD battery pack to power the switch. The battery pack will typically be connected to an RC receiver or servo controller, which passes the power on to the RC switch.
The included relay is an Omron G5LE-14-DC5 (1MB pdf) and is rated for up to 10 A under most conditions.
The Pololu RC Switch with Relay is available in two versions:
The board has four mounting holes that work with #2 or M2 screws (not included).
The RC switch provides feedback about what state it is in via a yellow indicator LED. Status information is also provided on two output pins:
More information about the Pololu RC Switch with Relay can be found in the user’s guide.
Polou also make an RC switch with a digital output for applications that just require a low-current digital signal, and a version of this switch with integrated MOSFETS instead of a relay: RC switch with a medium MOSFET (also has an integrated voltage regulator) .
