Shelly 4-Channel Decoupler 230V

The Shelly 4-Channel Decoupler 230V extends the functionality of the 1-channel model to four separate channels. This module converts up to four independent AC signals into isolated DC control signals, enabling the simultaneous control of four inputs on smart devices. Each of the four outputs is optically isolated from the input, ensuring safe galvanic isolation between the 230V circuit and the 12/24V control inputs. The 4-channel decoupler is ideal for integrating, for example, a quadruple wall switch or multiple conventional sensors into a smart home installation. This allows existing switches to control various scenes, lights, or devices in parallel, without allowing dangerous mains voltage to reach the smart devices. Like the 1-channel model, the Shelly 4-Channel Decoupler works reliably with Shelly Plus and Pro devices – including Shelly Plus RGBW PM, Shelly Pro RGBWW PM, Shelly Plus Uni, and Shelly Plus Add-On. By using existing switches and wiring, it significantly simplifies the retrofitting of more complex installations. Despite the quadruple power, the device remains compact and energy-efficient (<0.6 W consumption in standby). Overall, the Shelly 4-Channel Decoupler 230V offers a flexible solution to connect traditional controls or sensors to modern smart control systems and operate them safely.

Features:

• AC-to-DC signal conversion: Triggers DC inputs with standard AC signals for safe and reliable operation.
• Isolates and controls DC loads: Protects connected smart devices by isolating high AC voltages from their DC inputs.
• Compatible with multiple devices: Works with Shelly Plus RGBW PM, Shelly Pro RGBWW PM, Shelly Plus Uni, and Shelly Plus Add-On.
• Supports specialized switches: Designed for use with external and specialized controls like push buttons, relays, and potentiometers.

Application Examples:

• Integrate four separate wall switches into a smart installation.
• Control multiple scenes or functions with a 4-way switch.
• Parallel connection of multiple AC sensors (e.g., motion detectors) to Shelly devices.
• Secure triggering of various alarms or actions over multiple inputs on the Shelly Plus Add-On.
• Control smart lights and other devices simultaneously with existing switches.
