Compact receiver module for lighting control with dry contact, ideal for single-channel switching and integration in automation. Supports Wi‑Fi and Bluetooth for flexible connectivity and works across 110–240 V AC or 12/24/48 V DC inputs. A sober solution for technical projects.

General information about Shelly 1 Gen3 1-Channel Relay with Dry Contact

This device is a single-channel relay with a dry contact output designed to integrate lighting and electrical loads into a control system. It incorporates dual wireless connectivity via Wi‑Fi and Bluetooth for versatile integration in projects where compact size matters. The small form factor simplifies embedded installation inside enclosures or behind switches while maintaining safe control of the circuit.

The multi-voltage design accepts AC from 110 to 240 V and DC at 12, 24 or 48 V, broadening its application across different distribution schemes. Operating temperature is specified from -20 °C to +40 °C, supporting reliable configuration in technical environments. The enclosure material is PC. Use is indicated as Indoor. CE, EMC, LVD, RED, RoHS and UKCA certifications are listed for compliance needs.

Use and applications

Focused on switching a single lighting circuit or load, this relay enables on/off control within broader automation workflows. The dry contact output is suitable where galvanic isolation is required. In typical professional settings, it fits projects needing flexible connectivity and compact mounting, leveraging Wi‑Fi or Bluetooth and the multi-voltage input range to match existing electrical infrastructure.

When planning, consider the available supply (110–240 V AC or 12/24/48 V DC) and the intended network method. Commissioning and ongoing management can be centralised through an application if specified for the project. With its small dimensions, it integrates discreetly while providing reliable switching for technical installations.
