RC Switch with isolated SPST solid-state relay - 30V 10A - soldered connectors - Pololu 5424
The Pololu RC Switch is a compact , SPST solid-state relay controlled by an RC signal , designed to switch loads with voltages up to 30 V and currents up to 10 A. The module utilizes a pair of MOSFET transistors and an optically isolated control circuit, providing galvanic isolation of the load from the RC input . It supports high-side and low-side control, offers configurable switching thresholds, and a safe-start function. This version comes with pre-soldered connectors .

Product description: RC Switch with Isolated Solid State Relay SPST - 30V 10A - Soldered Connectors - Pololu 5424
The Pololu RC Switch allows you to control electrical devices directly using a standard radio control RC signal . The control circuit operates at voltages from 2.7 V to 16 V and analyzes the input pulse width, based on which it activates or deactivates a solid-state relay . The default switching threshold is approximately 1700 µs , and with learning mode, you can change both the threshold value and the activation direction. The actuator is a pair of anti-clockwise MOSFET transistors , providing a symmetrical output and enabling bidirectional current flow . This solution allows the module to be used as both a high-side and low-side switch. The absence of mechanical contacts means quiet operation and avoids the wear and sparking problems typical of electromechanical relays.
RC Switch with isolated SPST solid state relay - 30V 10A - soldered connectors - Pololu 5424.
Botland is an official distributor of Pololu electronics and robotics parts. Countless robots hold at least one component of this brand in their build. Our team guarantees that all Pololu products presented here are original.
The system supports a control voltage of 2.7 V to 16 V and can switch loads up to 30 V and 10 A.
Main features of the RC module
- SPST solid state relay : enables electronic switching of the load without mechanical contact elements
- Maximum load current 10 A : allows you to control devices that require relatively high current
- Load voltage up to 30V : 30V is the absolute maximum voltage for the switched circuit
- RC Signal Control : The module analyzes the pulse width coming from an RC receiver or servo controller.
- Adjustable activation threshold : Learning mode allows you to configure the switching threshold and direction of operation
- Default threshold around 1700 µs : normally the relay activates when the set pulse width threshold is exceeded
- Hysteresis ±64 µs : reduces unwanted switching when the signal is close to the threshold
- Safe-start function : reduces the risk of unexpected load switching when starting the system
- Galvanic isolation : optically isolated driver separates the control section from the load circuit
- Bidirectional MOSFET output : the push-pull connection of the transistors allows current to flow in both directions
- High-side and low-side control : symmetrical output allows flexible switch placement in the circuit
- OUT and GOOD outputs : allow you to monitor the relay status and the correctness of the received RC signal
- LED : allows for quick control of the current operating status of the module
- Soldered connectors : the module is equipped with a 1x3 goldpin connector with a 2.54 mm pitch and a 2-pin screw connector with a 3.5 mm pitch
- Small dimensions : compact board makes it easy to install in RC models, robots and other devices with limited space
