12-Ch 433MHz Industrial Rolling Code Wireless Relay Controller Kit

12-Channel 433MHz Industrial-Grade Rolling Code Wireless Relay Controller Kit

Take full wireless command of your equipment with this robust 12-channel relay controller kit. Operating on the 433MHz FSK frequency with rolling-code encryption (HCS301-compatible), this industrial-grade system delivers exceptional range — up to 300–500 metres in open space — and supports up to 32 paired remote controls simultaneously. Whether you're automating gates, lighting rigs, machinery, or custom electrical systems, this kit gives you the flexibility and security you need.

Made in Mainland China.

Key Features

• 12-Channel Control: Independently trigger up to 12 relay outputs from a single handheld RC44B12 industrial remote.
• Long-Range Wireless: +20dBm transmit power and -121dBm receiving sensitivity for 300–500m open-space range.
• Rolling Code Security: HCS301-style rolling code encryption prevents signal replay attacks, keeping your system secure.
• 8 Flexible Working Modes: Choose from Momentary, Self-Locking, Interlock, and four mixed-mode configurations to match your exact application.
• Wide Voltage Compatibility: Operates on DC 12V (24V optional) with low 8mA standby current — energy efficient for always-on installations.
• Heavy-Duty Relay Output: Each relay handles DC 1–110V / 5A or AC 85–265V / 6A loads via NO, COM, and NC terminals.
• Multi-Remote Support: Stores up to 30 uniquely coded remote controls in memory.
• Simple Learning Setup: One-button pairing process with LED confirmation — no special tools or software required.

Specifications

8 Working Modes Explained

1. Self-Locking: Relay latches ON with one press, OFF with the next. (Learn with Button 1)
2. Momentary: Relay is ON only while button is held; multiple channels can trigger simultaneously. (Learn with Button 2)
3. Interlock: Only one relay active at a time — activating one deactivates the previous. (Learn with Button 3)
4. Channels 1–6 Self-Locking + 7–12 Momentary: (Learn with Button 4)
5. Channel 1 Self-Locking + Channels 2–12 Momentary: (Learn with Button 5)
6. Channels 1 & 3 Self-Locking, Remaining Momentary: (Learn with Button 7)
7. Channels 1–10 Self-Locking with Master Open/Close via Buttons 11 & 12: (Learn with Button 8)
8. Channels 1–2 Interlock, 3–10 Momentary, 11–12 Self-Locking: (Learn with Button 7)

How to Pair (Learn) Your Remote

1. Press the KEY button on the receiver — the LED lights up, indicating learning mode.
2. Press the desired button on the remote control corresponding to your target working mode.
3. The LED flashes once to confirm successful pairing; if it turns off without flashing, retry.

To clear all stored remotes: Hold the KEY button for ~8 seconds until the LED goes out.

Frequently Asked Questions

Q: What is rolling code and why does it matter for a wireless relay controller?

A: Rolling code (similar to HCS301) generates a new encrypted signal with every button press, making it virtually impossible for anyone to capture and replay your remote's signal to trigger your relays unauthorised. This makes the system far more secure than fixed-code alternatives — ideal for gates, industrial machinery, and sensitive installations.

Q: How many remote controls can I pair with this wireless relay kit?

A: The receiver can store up to 30 individually coded remote controllers in memory, all operating the same 12 channels. It can also adapt (be compatible with) up to 32 remote controllers in total.

Q: Can I use this controller with both 12V and 24V systems?

A: Yes. The controller is designed for DC 12V by default, but a 24V version is also available. Make sure to select the correct voltage for your installation to ensure safe and reliable operation.

Q: What is the maximum load each relay can handle?

A: Each relay output supports up to DC 1–110V / 5A or AC 85–265V / 6A, making the kit suitable for controlling most standard electrical loads including lighting, motors, solenoids, and more.

Q: How do I change the working mode after initial setup?

A: To change the working mode, you must first clear all stored remotes by holding the KEY button on the receiver for approximately 8 seconds until the LED turns off. Then re-pair your remote using the button that corresponds to your desired new working mode.
