433MHz RF Remote Control Relay Switch DC 12V Gate Module

Universal 433MHz RF Remote Control Relay Switch – DC 12V Gate & Door Module

Take full wireless control of your gate, garage door, LED lighting, or other DC-powered devices with this compact Universal 433MHz RF Remote Control Relay Switch. Operating at DC 12V with a standard 433MHz radio frequency, this asking-code receiver module pairs quickly with a compatible remote to give you reliable, cord-free control from a distance — no complicated wiring or programming required.

Key Features

• Universal Compatibility: Works with most 433MHz RF remotes using asking (learning) code technology for easy pairing.
• Three Trigger Modes:
  • Momentary Mode: Relay engages only while the remote button is held down — ideal for brief activations.
  • Self-Locking (Toggle) Mode: Press once to connect the relay; press again to disconnect — perfect for gate or door control.
  • Auto-Off (Delay) Mode: Relay automatically disconnects after a set delay — choose from 5 seconds, 10 seconds, or 15 seconds (3 adjustable gear settings).
• DC 12V Input: Compact and easy to integrate into standard 12V systems including gate motors, garage doors, and LED lighting circuits.
• 433MHz RF Signal: Stable wireless reception with solid range for everyday indoor and outdoor use.
• Compact Module Design: Small form factor fits neatly into enclosures or mounting spots — great for DIY projects.
• 3 Channels Available: Choose the channel configuration that suits your setup.

Frequently Asked Questions

Q: What is the Universal 433MHz RF Remote Control Relay Switch used for?

A: This 433MHz RF relay switch module is designed to wirelessly control DC 12V-powered devices — most commonly automatic gates, garage doors, LED lighting circuits, and other home automation or DIY electronics projects. It receives a signal from a compatible 433MHz remote and triggers its onboard relay accordingly.

Q: How do I pair (learn) a remote control with this relay module?

A: This module uses asking-code (learning-code) technology. To pair a remote, press the onboard learning button on the module until the indicator light responds, then press the button on your 433MHz remote. The module will store the code. Refer to the included instructions for your specific channel and mode configuration.

Q: What are the three operating modes and how do I switch between them?

A: The module supports three modes: Momentary (relay is active only while the remote button is pressed), Self-Locking / Toggle (press once to activate, press again to deactivate), and Auto-Off Delay (relay activates and automatically deactivates after 5, 10, or 15 seconds). The mode is typically selected via a jumper or onboard switch — consult the product documentation for exact steps.

Q: Is this module suitable for a garage door or gate opener?

A: Yes — this is one of the most popular uses for this type of relay switch module. The self-locking or momentary mode works seamlessly with most 12V gate and garage door motor systems. Ensure your gate or door motor operates on DC 12V and is compatible with a standard relay dry-contact trigger before installation.

Q: What is the wireless range of this 433MHz receiver module?

A: Typical open-air range for 433MHz RF modules is approximately 20–100 metres depending on environmental conditions, obstructions, and the transmitter power of the paired remote. Performance may vary in enclosed or signal-obstructed environments.
