Shelly 1-Channel Decoupler 230V

The Shelly 1-Channel Decoupler 230V is a compact module that converts an AC signal into a safe DC control signal. It connects two separate circuits (alternating current to direct current) via an optical interface, allowing conventional 230V switches and relays to safely communicate with smart low-voltage devices. This accessory makes it possible to integrate existing wall switches or sensors into modern smart home systems without significant changes to the existing electrical installation. Through galvanic isolation via optocoupler, high grid voltages are kept away from the sensitive DC inputs, increasing safety and reliability. The 1-Channel Decoupler is ideal for applications where a single AC switch is meant to control a smart device – for example, to activate LED strips or alarm systems. The signal is transmitted in isolation so that the coupled Shelly device does not receive direct AC power. The Shelly 1-Channel Decoupler is compatible with Shelly Plus and Pro devices (e.g., Shelly Plus RGBW PM, Shelly Pro RGBWW PM, Shelly Plus Uni, Shelly Plus Add-On) and thus offers a wide range of possibilities in home automation. With its small size, it fits into many flush-mounted boxes or distributors and consumes less than 0.6 W in standby, making it very efficient. Overall, the 1-Channel Decoupler facilitates the retrofitting of existing installations while simultaneously protecting the connected smart devices from overvoltage from the power grid.

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 such as push-buttons, relays, and potentiometers.

Application examples:

• Controlling LED strips via existing wall switches.
• Secure triggering of alarms or irrigation systems via Shelly Plus Add-On.
• Integrating existing AC switches into a smart lighting control.
• External AC
