30A RF 433MHz Remote Control Relay – Effortless 3000W Wireless Switching
Need to control a water pump, lighting system, or motor without walking to the distribution board? This 8V–80V DC wireless RF relay gives you total remote control—no apps, no Wi-Fi, and no complex setup required. It comes with two remotes and features four versatile operating modes, allowing for a quick 10-minute installation.
Note: The actual operating voltage is DC 8V–80V. The 12V, 24V, 48V, 60V, and 72V ratings indicate compatibility with common DC systems within this range. The maximum load is 30A; please do not exceed this limit to ensure circuit safety.
Why choose this model? (Key Advantages):
- Universal DC Compatibility (8V–80V) — Works natively with 12V, 24V, 48V, 60V, and 72V systems without the need for extra converters or adapters.
- High-Capacity 30A (3000W) Switching — Easily handles water pumps, electric motors, automotive lighting, and industrial actuators without overheating.
- 2 Ready-to-Use Remotes Included — Everything you need is in the box; simply pair and go.
- 4 Programmable Operating Modes — Choose between Momentary, Toggle, Latched, and Delay (5, 10, 15, or 20 seconds) to suit any automation scenario.
- High-Sensitivity -110dBm Receiver — Ensures stable signal reception, even through walls or in environments with electromagnetic interference.
- Software-Free Programming — Configure everything via the onboard ‘Learn’ button; the LED provides clear visual feedback for every step.
- Wide Temperature Range (-20°C to +80°C) — Suitable for indoor electrical panels, industrial setups, or vehicle installations.
Performance and Specifications
At the core of this module is a 433.92MHz RF receiver with ASK modulation and Learning Code technology, allowing you to pair compatible remotes in seconds without tools. With a standby current of ≤10mA, the module is highly energy-efficient. The relay contacts support a continuous 30A load, and the compact 66.2 × 43.7 × 29.7 mm footprint makes it easy to fit into any existing distribution box.

Frequently Asked Questions
Can I use this relay for both 12V and 24V?
Yes. The module accepts any DC voltage between 8V and 80V. Simply connect it to your power source (12V, 24V, 48V, 60V), and it will function immediately without modifications.
How many remotes can I pair?
The module supports multiple RF 433MHz remotes using Learning Code. You can repeat the pairing procedure for each additional remote without erasing previously saved codes.
Is it compatible with my existing remotes?
It is compatible with 433.92MHz remotes using Learning Code (EV1527 or similar). Remotes with fixed codes or different frequencies are not supported.
Can I use the delay mode for a water pump?
Absolutely. Use the Delay mode to have the pump turn off automatically after 5, 10, 15, or 20 seconds. Just ensure your pump’s current draw does not exceed 30A.
Is this suitable for outdoor use?
The module is rated for temperatures between -20°C and +80°C, but it is not waterproof. For outdoor applications, please house it in an IP65-rated enclosure.
