DC 12V RF 433MHz Relay Receiver Module – Gate & LED Switch 10A
DC 12V RF 433MHz Smart Relay Receiver Module
Take full wireless control of your gate, garage door, LED lighting, and more with this compact DC 12V RF 433MHz Relay Receiver Mini Module. Supporting up to 10A load and four flexible operating modes, this CE-certified receiver board is an ideal solution for DIY automation, access control, and remote switching applications.
Key Features
- Universal RF 433MHz compatibility — works with any EV1527-coded remote transmitter
- 10A relay capacity — handles up to 110W maximum load power
- Four operating modes: Momentary, Toggle, Latching, and Time Delay (5s / 10s / 15s)
- Stores up to 25 remote controls for flexible multi-user setups
- NC / COM / NO wiring terminals for normally-open or normally-closed circuit configurations
- 50m wireless range (open space) for reliable distance operation
- Compact mini module design — easy to integrate into enclosures or control panels
- CE Certified — meets low-voltage directive standards (below 50V AC or 75V DC)
About the Operating Modes
Momentary: Hold the remote button to connect the relay; release to disconnect.
Toggle: Press once to connect the relay; press again to disconnect.
Latching: Press Button A to connect; press Button B to disconnect. Ideal for gate control.
Time Delay: Press the button to connect the relay; it automatically disconnects after 5s, 10s, or 15s (selectable).
How to Learn a Remote Code
- Momentary: Press the learning key once → LED goes off → press remote button → LED flashes then off → after 3 seconds LED comes back on = success.
- Toggle: Press the learning key twice → same LED sequence as above.
- Latching: Press learning key three times → press Button A (LED flashes 5×) → press Button B (LED flashes 5×) → after 3 seconds LED on = success.
- Time Delay 5s: Press learning key 4 times. 10s: 5 times. 15s: 6 times. Then press remote button → LED flashes → after 3 seconds LED on = success.
Clearing All Stored Codes
Press the Learning Button on the receiver 8 times to erase all stored codes. Once cleared, no previously paired remote will operate the receiver until re-paired.

Frequently Asked Questions
Q: What devices can I control with this RF 433MHz relay receiver module?
A: This module is designed for a wide range of low-voltage switching applications including garage door openers, gate controllers, LED lighting strips, small motors, and other 12V DC-powered devices with loads up to 10A / 110W.
Q: How many remote controls can be paired with this relay receiver?
A: The receiver can store up to 25 individual remote controls. If you attempt to add a 26th remote, the oldest stored code will be overwritten. You can clear all stored codes at any time by pressing the learning button 8 times.
Q: What is the difference between Momentary, Toggle, and Latching modes?
A: Momentary keeps the relay active only while the button is held down. Toggle switches the relay on with one press and off with the next. Latching uses two separate buttons — one to turn the relay on and one to turn it off — making it ideal for gate or door control. Time Delay mode automatically disconnects the relay after a set time (5, 10, or 15 seconds).
Q: Is this module compatible with standard 433MHz RF remotes I already own?
A: Yes — as long as your existing remote uses the EV1527 encoding format and operates at 433MHz, it can be paired with this receiver module using the learning code procedure.
