The optoisolator effectively separates the AC and DC sections, protects connected devices from overvoltage, and ensures stable switching of inputs.
Compact body (44 × 34 × 7 mm), weight only 25 g, and pre-terminated leads make installation easy even in small boxes.
Seamless integration with SHELLY products for smart lighting, relays, and sensors lets you build complex automation scenarios.
The Shelly four-channel isolator 230 V converts standard AC signals into safe DC triggers while providing galvanic isolation between circuits. With compact dimensions and low power consumption, it’s a great choice for renovations and new installations where you want to keep existing control elements.
The device is compatible with the SHELLY ecosystem (e.g., Shelly Plus RGBWW PM, Shelly Pro RGBWW PM, Shelly Plus Uni, Shelly Plus Add-On), so you can easily integrate it into smart lighting, buttons, and relays. Connect external sensors (PIR, microwave, light) and buttons to create flexible automation scenarios.
