SHELLY 1-Channel Decoupler 230V

The Shelly 1-Channel Decoupler 230V is a small decoupling module that generates a safe, low-voltage direct current (DC) starting signal from an existing 230 V~ alternating current signal (e.g. wall switch, relay output). Thus, the DC inputs of the Shelly devices can also be driven with AC-side control elements, while the optical isolation (optocoupler) protects the smart devices from mains voltage.

Ideal for retrofitting: the existing 230 V wall switch can remain in place, but the signal is already sent to the DC inputs of the Shelly Plus/Pro RGBW controllers, which can thus control LED strips, scenes, brightness or colors. The module is available in a 1-channel version and requires a wired connection.

Compatible with, among others, Shelly Plus RGBW PM, Shelly Pro RGBWW PM, Shelly Plus Uni and Shelly Plus Add-on devices, as well as various external controls (push buttons, switches, special sensors).

Main product features

- AC→DC signal conversion: produces a low-voltage DC start signal for the digital inputs of Shelly devices from a 230 V~ input signal.
- Optical isolation: the optocoupler solution electrically separates the mains and low-voltage sides.
- Ideal for retrofitting: safely transmits the signals of existing 230 V wall switches and relays to the DC inputs.
- Wide compatibility: works with Shelly Plus RGBW PM, Shelly Pro RGBWW PM, Shelly Plus Uni and Shelly Plus Add-on devices.
- 1-channel design: a DC start signal can be generated from an AC signal.

Smart home protocols and platform compatibility

- Type: passive, wired additional module (not controllable).
- Compatibility: Shelly Plus RGBW PM, Shelly Pro RGBWW PM, Shelly Plus Uni, Shelly Plus Add-on; as well as for transmitting signals from various external controls (switches, push buttons, special sensors).
- Operation: the actual control/automation is performed by the connected Shelly device.

Smart functions

- Safe start signal: the physical event of the 230 V~ connection is transmitted as a DC trigger to the input of the Shelly device.
- Scenes and control: the connected Shelly (e.g. RGBW controller) can set light, brightness, colors or scenes based on the incoming trigger.
- Flexibility: the AC signal of external sensors (PIR, microwave, hand wave, light sensor) can also be "transferred" to DC inputs.
