This is a NEW 10A RC TX Controlled Relay Switch PWM Receiver LED Control Spray Switch Normal Mode: The module can read a pulse width that can range from 400 to 2600us. If the width of the pulse is more than 1800us, the MOSFET switch will close, if less than 1200us, the MOSFET switch will open. Safe-protection Function: This module has a safe-protection feature that reduces the likelihood of unexpected activation. In the below 2 conditions the Safe-protection mode will active: 1. The pulse is more than 1800us at first power-up, the MOSFET switch open. The LED will blink, you should move the input to the off position, then normal more will active; 2. The signal is bad continuously for 500ms, the MOSFET switch open. The LED will blink. When the signal is good, the device will deactivate safe-protection mode. LED:(Normal mode) The LED will on when input pulse >1800us; The LED will off when input pulse <1200us; Safe-protection mode: the LED will fast blink.
