Description

This relay switch module acts as a high-current electronic switch, controlled by a spare auxiliary channel on any standard PWM receiver. It interprets a PWM pulse width between 400-2600µs, closing its internal MOSFET switch when the pulse exceeds 1800µs and opening it below 1200µs, enabling remote activation of lights, spray systems, or other auxiliary payloads.

The module incorporates a robust safe-protection function to prevent unintended operation. This mode activates if the initial signal at power-up is in the ‘on’ state (>1800µs) or if a valid signal is lost for more than 500ms, forcing the switch to open and causing the LED to blink until normal conditions are restored. Its design is optimized for reliability in UAV and robotic applications where remote switching is required.

Key Features

  • High-Current MOSFET Switch: Handles up to 10A continuous DC load, suitable for LEDs, pumps, and small actuators.
  • Broad Voltage Compatibility: Operates with input voltages from 5V to 28V DC, supporting a wide range of LiPo and power supply configurations.
  • Intelligent Safe-Protection Logic: Features built-in safeguards against signal loss and improper power-up sequences for enhanced operational safety.
  • Standard PWM Interface: Connects directly to any receiver's PWM output channel, requiring no complex configuration.
  • Clear Status Indication: Integrated LED provides immediate visual feedback on switch state and protection mode activity.
  • Durable Wiring: Equipped with 100mm leads using 20AWG wire for robust power handling and easy soldering or connection.

Applications

  • Remote activation of LED light strips or landing lights on FPV racing and freestyle drones.
  • Controlling auxiliary functions like spray modules or payload releases on agricultural or utility UAVs.
  • Switching power to FPV video transmitters or cameras via a dedicated RC channel.
  • Integrating sound modules or telemetry beacons for search-and-rescue or show drone applications.
  • General-purpose high-current switching in robotics and RC car projects.

Frequently Asked Questions

What is the input voltage range for this relay switch module?

The module accepts a wide DC input voltage range from 5V to 28V. This allows it to be powered directly from a wide variety of sources, including a 5V BEC from your flight controller, a 2S-6S LiPo battery via a suitable regulator, or an external power supply. Ensure your connected load is rated for the same voltage.

How do I connect and configure this switch with my RC receiver?

Connect the module's 3-pin 'RX' lead (signal, positive, ground) to any spare PWM output channel on your receiver. The power input leads connect to your chosen 5-28V DC source and the load you wish to switch. No software configuration is needed. Simply assign the corresponding transmitter channel to a switch or knob, ensuring it outputs a PWM signal where the high position (>1800µs) turns the load on.

What does the safe-protection mode do and when does it activate?

The safe-protection mode is a safety feature that prevents the connected load from turning on unexpectedly. It activates in two scenarios: first, if the PWM signal is already in the 'on' state (pulse >1800µs) when the module is initially powered up; second, if a valid PWM signal is lost for more than 500 milliseconds. In both cases, the module forces the switch to open (off) and the LED will blink until normal signal conditions are restored.
