Multi-Frequency Compatibility: Works with 300MHz, 433MHz, 868MHz and other common RF frequencies, supporting fixed code & rolling code remotes.
Dual Channel Output: 2 independent relay channels (CH1/CH2), for controlling two separate devices or functions.
Wide Voltage Input: Supports AC/DC 9-30V and AC 85-250V power supply, flexible for different installation scenarios.
Easy Learning Mode: Simple DIP switch & button pairing, no complex programming required. Up to 100+ remote controls can be stored.
Stable Performance: Anti-interference design, CE certified, reliable for industrial and residential use.
Compact Design: Small size with terminal block wiring, easy to install in gate control boxes or electrical panels.

How to Learn & Use
1. Set the DIP switches to match your remote’s frequency & code type (refer to manual).
2. Press and hold S1 (for CH1) or S2 (for CH2) until the indicator L1/L2 lights up, entering learning mode.
3. Press the target button on your remote transmitter; the indicator will flash to confirm successful learning.
4. To clear all paired remotes: Press and hold the corresponding button for 5-10 seconds until the indicator flashes rapidly.
5. Test the relay output to confirm normal operation.

Important Notes
This is a receiver only; it must be used with a compatible RF remote transmitter (300-868MHz).
Ensure the power supply voltage matches your device (AC/DC 9-30V or AC 85-250V).
Professional wiring is recommended to avoid short circuits or electrical hazards.
Not compatible with encrypted high-security systems without specific learning support.
