AC 220V 30A Relay Wireless Remote Switch 433MHz

Key Features

• Jog Mode — The relay closes while the button is held and opens when the button is released.
• Self-Locking Mode — One press pulls the relay in, and the next press disconnects it.
• Interlock Mode — Two buttons control the relay: the A button closes it and the B button disconnects it.
• Timed Delay — After pairing, the relay disconnects automatically after 5, 10, 15 or 20 seconds.

What It Is / How It Works

This AC 220V 30A universal remote control switch is a wireless remote control transmitter paired with a relay receiver. The transmitter sends a code to the receiver, which then closes or opens the relay in the learning mode you set.

Who It's For / Use Cases

Remote control switches like this suit people who want to switch a light, lamp, water pump or door device on and off from a handheld transmitter instead of a wall switch. They suit simple on-off control where the switched load stays within the relay's rating.

How to Use / Care

1. Press the controller learning button twice to enter the jog or self-locking learning state; the indicator light flashes twice quickly.
2. Press the remote control button you want to learn; the indicator light flashes three times and goes out when code matching is complete.
3. Test the learned button: in self-locking mode, the first press pulls the relay in and the next press disconnects it.
4. To clear stored codes, press and hold the learning button for 8 seconds without letting go until the receiver indicator flashes 6 times quickly.

How to Choose

Check the load before you choose a setup. The rated contact current is 15A/240VAC and 15A/110VAC, and the 30A marking is for peak current, so the rated current of your load should be less than 15A. Match the AC 110V - 240V operating range to your power source, then pick the mode, such as jog, self-locking, interlock or timed delay, that fits how you want the switch to behave.

Frequently Asked Questions

What is the transmission distance?
It has a transmission distance of 100M in an open field, and its receiver sensitivity is rated above -105dB.

Can it switch a 30A load?
The relay is marked 30A 240VAC, but its rated contact current is 15A/240VAC and 15A/110VAC. The 30A figure is the peak current for your load, so the rated current of your load should be less than 15A.

What operating voltage does it need?
The operating voltage is AC 110V - 240V, and the 220V listed in the title falls within that range.

What frequency does it operate on?
It operates at 433MHz, the same as its remote control, and uses learning code encoding.

Which certifications does it carry?
It carries CE and RoHS certification marks.
