The Shelly 4-Channel Decoupler 230V is a four-way isolation module that safely converts an existing 230 VAC signal (e.g., from a wall switch or relay output) into a low-voltage DC trigger signal. This allows AC-side control elements to drive the digital (DC) inputs of Shelly devices without bringing mains voltage directly onto the low-voltage side.
It’s ideal for retrofits and renovations: existing switches remain in place, while the signal is routed to the DC inputs of Shelly Plus/Pro RGBW controllers or to Shelly Plus Uni or Plus Add-on. The four-channel design enables independent handling of multiple circuits within a single compact module.
The module is a wired, passive accessory; actual logic/automation runs on the connected Shelly device. Optical isolation increases safety and reliability in mixed (AC–DC) systems.

Key Product Features
- Isolation and control of DC loads: Use existing AC to drive the inputs of DC devices. Suitable for retrofits and external/special switches.
Smart Home Protocols and Platform Compatibility
- Type: passive, wired accessory (non-networked device).
- Compatible Shelly devices: Shelly Plus RGBW PM, Shelly Pro RGBWW PM, Shelly Plus Uni, Shelly Plus Add-on.
- Usage: enables triggering DC inputs from an AC supply with optical isolation; control and automation are handled by the connected Shelly device.
Smart Features
- Safe signal transfer: converts a 230 VAC switching event into a low-voltage DC trigger.
- Multi-circuit control: four independent channels can be wired to separate DC inputs and functions.
- Flexible application: forwards signals from switches, push buttons, or AC-output sensors (e.g., PIR, microwave, gesture, light sensor) to DC inputs.
