Short description
Shelly 1-Channel Decoupler 230V / Shelly 4-Channel Decoupler 230V is an electronic component that interconnects two separate electrical circuits (AC to DC) by means of a light sensitive optical interface (an octocoupler). It is designed for use with Shelly Plus Uni, Plus Add-on, Plus RGBW PM and Pro RGBW PM devices and different controllers, such as switches and buttons. It allows for switching DC inputs using AC supply.
Main features
-
Isolate and control DC loads: Use existing AC for triggering inputs on DC devices. Suitable for retrofits, external/specialized switches.
Use cases
-
Third-party sensor connectivity: Connect third-party sensors that require/work on/with AC to DC Inputs, for example - PIR, Microwave, Light control, Infrared motion, Hand wave sensors.
