RC Receiver Controlled On/Off Lighting Switch PWM Receiver LED Control Spray Switch Remote Electronic AUX Channel Relay

Features:
This module is a nice little relay switch controlled by a spare auxiliary channel on your receiver. Ideal for switching lights, sound and any other auxiliary electrical items.
when PWM duty is more than 1800us, the switch will turn on; when PWM duty is less than 1200us, the switch will turn off.

Specifications:
RX lead length:100mm
Power in/out lead length:100mm (each)
Switching load current (DC):5A (Continuous current)
Input Voltage (DC):5-28V

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 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 deactivates 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
