Shelly 4-Channel Decoupler 230V

The Shelly 4-Channel Decoupler 230V converts AC signals to DC to control Shelly smart devices

The Shelly 4-Channel Decoupler 230V allows you to safely and accurately activate direct current (DC) inputs using an alternating current (AC) signal . Its optically isolated design (optocoupler) prevents interference and protects smart devices by separating the AC and DC circuits.

Ideal for integrators or professional installers looking for full compatibility with the Shelly ecosystem , including Shelly Plus RGBW PM , Shelly Pro RGBWW PM , Shelly Plus Uni and Shelly Plus Add-On .

Main features

• Safe AC to DC conversion: Converts AC signals into DC pulses to trigger digital inputs without risk of overload.

• Complete optical isolation: protects smart devices from high voltages and prevents electrical damage.

• Wide compatibility: Works perfectly with Shelly Plus and Pro controllers.

• Multi-channel design (4 outputs): allows managing several independent inputs from a single AC source.

• Compact installation: small size, ideal for professional integration or retrofit projects.

Recommended uses

• External sensor integration: connects PIR, motion, light or microwave sensors that operate on AC, translating them to DC signals.

• DC load control with existing AC switches.

• Professional home automation projects: facilitates communication between Shelly devices with different voltages.

• Automation of commercial or residential spaces where isolation between control and power signals is required.
