4-Channel 433MHz Wireless Relay Module – AC 90-220V Controller
4-Channel 433MHz Wireless Relay Module Controller – AC 90-220V
Take full command of your gates, doors, LED lighting, and other AC-powered devices with this versatile 4-Way 433MHz Wireless Relay Module Controller. Supporting AC 90–220V input, this compact receiver module gives you the flexibility to trigger up to four independent channels using three switchable operating modes — all from up to 50 meters away via the included optional RF remote control.
Whether you're automating a driveway gate, managing multiple LED circuits, or building a custom smart-home control panel, this relay module delivers reliable, interference-resistant 433MHz RF communication with a durable PC-cased housing built for long-term use.
Key Features
- Wide Voltage Compatibility: Operates on AC 90–220V for easy integration into standard household and industrial circuits.
- 3 Flexible Trigger Modes: Switch between Jog (Momentary), Self-Locking (Toggle), and Interlocking (Mutual Exclusion) modes to match your application.
- Mixed-Mode Support: Combine modes across channels — e.g., two channels in jog mode and two in self-locking — for advanced automation setups.
- RF Remote Control Range: The 4-button remote operates reliably at 30–50 meters; the receiver itself has no distance limit when wired directly.
- Learning Code Pairing: Simple button-press code-pairing with LED confirmation flashes — no complex software needed.
- Durable PC Shell: High-quality polycarbonate enclosure protects internal components for extended service life.
- Factory Reset: Quickly clear all paired remote codes with an 8-press reset sequence.

Operating Modes Explained
- Jog (Momentary): Relay activates only while the button is held. Ideal for pulsed signals (e.g., gate triggers). Pair: press pairing button 1×.
- Self-Locking (Toggle): Relay stays ON after one press, turns OFF on next press. Ideal for lights or fans. Pair: press 2×.
- Interlocking (Mutual Exclusion): Only one relay can be active at a time — activating one turns off the others. Ideal for motor direction control. Pair: press 3×.
- Mixed Modes (4×–7×): Combine jog, self-locking, and interlocking across the four channels for complex automation needs.
- Factory Reset: Press pairing button 8× to clear all stored remote codes.

Frequently Asked Questions
Q: What devices can I control with this 4-channel wireless relay module?
A: This relay module is compatible with a wide range of AC-powered devices including electric gates, door openers, LED lighting strips and fixtures, motors, fans, and other AC 90–220V appliances. Its three trigger modes make it suitable for both simple on/off switching and more advanced interlocked control applications.
Q: How do I pair the 433MHz remote control with the relay receiver?
A: Pairing is simple and tool-free. Press the pairing button on the control board the number of times that corresponds to your desired mode (e.g., once for Jog, twice for Self-Locking, three times for Interlocking). The LED will flash the same number of times. Once the LED stays on, press the desired button on your remote — the LED will flash three times to confirm successful pairing.
Q: Can I use multiple remotes with one receiver module?
A: Yes. The learning-code system allows you to pair multiple remote controls to a single receiver. Simply repeat the pairing process for each additional remote. To clear all stored remotes and start fresh, press the pairing button 8 times consecutively to trigger a factory reset.
Q: What is the difference between Jog, Self-Locking, and Interlocking modes?
A: Jog (Momentary) keeps the relay active only while the button is pressed — perfect for gate pulse signals. Self-Locking (Toggle) turns the relay on or off with each button press — ideal for lighting or fans. Interlocking ensures only one relay channel is active at a time, preventing conflicts — useful for forward/reverse motor control or exclusive switching scenarios.
Q: Is a remote control included in the package?
A: This product is available in two configurations: (1) Relay Module + Shell only, or (2) Relay Module + Shell + 4-Button Remote Control. Please select the bundle option that includes the remote if you need wireless control out of the box. The remote requires a CR2032 button-cell battery.
