Shelly 4-channel 230V decoupler (4CHD230V)

Shelly 4-Channel Decoupler 230V
Shelly 4-Channel Decoupler 230V is a compact module that allows safe and precise triggering of DC inputs using standard AC signals. Thanks to its optoisolator, it effectively separates electrical circuits, protecting connected devices from high voltage and ensuring stable system operation.

Ideal for retrofitting installations
The Shelly 4-Channel Decoupler 230V model is great for retrofit projects - it allows you to use existing AC switches to control DC devices. It's a great solution for those retrofitting lighting or automation systems who want to keep their existing controls.

Compatibility with the Shelly ecosystem
The device is compatible with many products in the Shelly portfolio, including the Shelly Plus RGBW PM, Shelly Pro RGBWW PM, Shelly Plus Uni and Shelly Plus Add-On. So you can easily integrate them with smart lighting, relays or buttons to create a cohesive and flexible automation system.

Support for sensors and buttons
The Shelly 4-Channel Decoupler 230V allows you to connect external buttons, relays and sensors - such as PIR, microwave motion sensors, lighting controllers or proximity sensors. This allows you to build a fully customized system that responds to motion, light or the presence of household members.

Compact and robust design
The module measures just 44 × 34 × 7 mm and weighs only 25 g, making it easy to install even in confined spaces. The white housing and clearly marked wires (brown, blue, red, black) make installation quick and hassle-free. The length of the wires is 80 mm and the prepared 5 mm terminations allow efficient connection in installation boxes.

Efficiency and energy saving
The device operates in the voltage range of 230 V~ 50 Hz, consuming less than 0.6 W of power, making it an energy-saving component of any installation. The operating temperature range of 0°C to 40°C and humidity of 30-70% RH guarantees reliability in typical home and office conditions
