Product Detail

- Receiver board – 4 independent 10A relays, antenna, indicator light, learning button
- 2 x RF transmitters – silicone buttons, indicator light, metal keychain, powered by CR2032 battery (included)
- Each relay has three terminals: NO (Normally Open), COM (Common), NC (Normally Closed)
Wiring Diagram

- Power input: Connect DC 6V-30V to VCC (+) and GND (-)
- Relay output (dry contacts): Four independent relays (NO/COM/NC)
- Examples: AC lamp (1V-250V), curtain motor (DC 12V, 30V), garage motor (AC 110V, 220V, 250V)
Warning
- Always disconnect power before performing any wiring or maintenance.
- Do not exceed the maximum current rating of 10A per relay.
- Ensure input voltage is within DC 6V-30V.
- Keep the device away from water, moisture, and extreme temperatures.
- If unsure about wiring, consult a qualified electrician.
- Usually the receiver and transmitter have been paired in factory. If not, reprogram them.
- Reset before you want to change the operating mode.
- After reset, all remote controls cannot work anymore.
- Replace the battery in time when the remote transmitter voltage is low.
Operating Mode
The receiver supports three operating modes. Follow the programming steps below.
Momentary Mode
Press and hold a button → relay activates (device ON)
Release the button → relay deactivates (device OFF)
How to program:
- Press the learning button on the receiver 1 time. The indicator light will illuminate.
- Press any button on the remote control. The indicator light will flash, confirming successful programming.
Toggle Mode
Press a button once → relay activates (device ON)
Press the same button again → relay deactivates (device OFF)
How to program:
- Press the learning button on the receiver 2 times. The indicator light will illuminate.
- Press any button on the remote control. The indicator light will flash, confirming successful programming.
Latched Mode
Press button A → Relay 1 turns ON (Relay 2 turns OFF)
Press button B → Relay 2 turns ON (Relay 1 turns OFF)
How to program:
- Press the learning button on the receiver 3 times. The indicator light will illuminate.
- Press button A on the remote control.
- Press button B on the remote control. The indicator light will flash, confirming successful programming.
Note: In Latched mode, one relay turns ON while another turns OFF, ensuring only one is active at a time.
Reset
To clear all programmed remote controls and reset the receiver to its default state, press the learning button 8 times. The indicator light will flash, confirming that all previous pairings have been cleared.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Remote not responding | Out of range; Low/dead battery; Receiver not powered; Remote not paired | Move closer; Replace CR2032 battery; Verify DC 6V-30V power; Re-program remote |
| Relay not activating/deactivating correctly | Incorrect wiring; Wrong operating mode; Overload | Check wiring against diagrams; Reprogram desired mode; Ensure load ≤10A |
| Accidental activation or erratic behavior | RF interference; Unintended signals | Reset receiver (press learning button 8 times); Re-program only desired remotes; Keep away from strong EMI sources |
Maintenance
- Cleaning: Wipe with a dry, soft cloth. Do not use harsh chemicals or abrasive cleaners.
- Environment: Keep receiver in a dry location, away from moisture, extreme temperatures, and corrosive substances.
- Battery replacement: Replace remote CR2032 battery when range decreases or LED dims.
- Wiring: Periodically check all connections for wear, corrosion, or looseness.
- Avoid overloading: Do not exceed 10A per relay.
