Shelly 4-Channel Decoupler – AC to DC Converter

Eliminate the hassle of bridging standard 230V AC wall switches with low-voltage smart modules. The Shelly 4-Channel Decoupler is a compact isolation module designed to safely convert up to 4 independent 230V AC inputs into low-voltage DC trigger signals. Your delicate smart home controllers remain optically isolated and fully protected from high mains voltage.

Perfect for RGBW Controllers and Sensors

This module is engineered for seamless retrofitting. It allows you to keep your existing high-voltage AC wall switches in place while safely routing their switching signals to the DC inputs of your smart controllers. This device is highly compatible with modules such as the Shelly Plus RGBW PM, Shelly Pro RGBWW PM, Shelly Plus Uni, and third-party devices like the FIBARO RGBW Controller 2.

Technical Specifications:

• Function: Optical isolation (optocoupler) converting 4× AC inputs into 4× DC triggers.
• Input Voltage: 230V AC, 50 Hz.
• Output Trigger: Low-voltage DC signal (Max. 2.4 mA).
• Power Consumption: Ultra-low (< 0.6 W).
• Installation: Passive wired add-on module (does not require dedicated mains power; it operates purely on the input signal).
