The 10A RC TX Controlled Relay Switch PWM Receiver with LED Control Spray Switch is a versatile module designed for use in various remote-controlled applications. It allows you to control high-power devices using a PWM signal from your RC transmitter. Here’s a detailed overview of its features, specifications, and usage.
 
This relay switch module is engineered to operate with a PWM signal, enabling it to control devices like lights, sound systems, or other electrical equipment effectively. Its safety features and LED indicators enhance usability and reliability, making it an excellent choice for hobbyists and professionals alike.
 
Key Features
Normal Mode Operation:
The module can interpret pulse widths ranging from 400 to 2600 microseconds (µs).
If the pulse width exceeds 1800 µs, the MOSFET switch closes, activating the connected device.
If the pulse width is below 1200 µs, the MOSFET switch opens, deactivating the device.
Safe-Protection Function:
The module is equipped with a safety feature to prevent accidental activation:
First Power-Up Protection: If the pulse is more than 1800 µs during initial power-up, the MOSFET switch remains open, and the LED blinks. Move the input to the off position to activate normal mode.
Signal Loss Protection: If the signal remains bad for 500 milliseconds, the MOSFET switch opens, and the LED blinks. The device will deactivate safe-protection mode once the signal is restored.
LED Indicators:
Normal Mode:
The LED lights up when the input pulse is greater than 1800 µs.
The LED turns off when the input pulse is less than 1200 µs.
Safe-Protection Mode: The LED blinks rapidly to indicate protection mode activation.
