Product description: Shelly Decoupler - 4-channel decoupler 230 V
The Shelly Decoupler is a functional 4-channel 230V module measuring 44 x 34 x 7 mm that converts AC signals into safe DC pulses for controlling digital inputs in other devices. Using an optocoupler, it effectively separates high-voltage circuits from low-voltage systems , protecting connected components. The device is ideal for retrofitting lighting and automation installations , enabling the use of existing AC switches in a Smart Home environment.
Shelly Decoupler - 4-channel decoupler 230 V.
The module enables safe and precise triggering of DC inputs using standard AC signals.
Main features of the module
- 4 DC signal channels: converts 230 V AC signal into 4 independent DC signals for digital inputs in Shelly devices
- Signal isolation: effective separation between AC and DC circuits thanks to the use of optocouplers
- Shelly Compatibility: Works with Shelly Plus RGBW PM, Shelly Plus Add-On, Shelly Plus Uni, Shelly Pro RGBWW PM
- Compact dimensions: only 44 x 34 x 7 mm, easy installation in boxes and distribution boards
- Sensor and switch support: works with buttons, relays and sensors such as PIR, microwave, proximity
- Low energy consumption: power consumption less than 0.6 W
- Standard operating voltage: 230 V~ 50 Hz
Shelly Smart Control and full compatibility
The module is fully compatible with the Shelly intelligent ecosystem. It supports devices such as the Shelly Plus RGBW PM, Pro RGBWW PM, Plus Uni , and Plus Add-On . Integration allows you to create scenes, automations, and control based on physical AC buttons . Thanks to the signal decoupling function, you can safely use classic switches to trigger actions in digital devices.
Universal connection and quick installation
Thanks to its well-thought-out design and pre-wired cables (80 mm long, 5 mm stripped), connecting the module to the system is quick and hassle-free . Clearly marked wires (brown, blue, red, black) allow for intuitive installation. The device can be hidden in standard junction boxes , and weighs just 25 g.
Shelly Decoupler allows you to connect external buttons, relays and sensors.
Its compact dimensions make it easy to install even in limited spaces.
