General information about Shelly PRO 1 1-Channel Relay With dry contact for DIN rail

This device is a DIN rail relay for lighting control and electrical loads, designed to integrate into distribution boards and technical enclosures. It provides a dry contact output, making it suitable for switching circuits without passing supply through the relay. Connectivity via Wi‑Fi enables remote interaction and integration in connected lighting systems, while Bluetooth supports proximity-based setup and quick commissioning. The compact enclosure supports track mounting with dimensions optimised for standard rails.

With control and integration capabilities, the relay enhances system-level configuration across connected installations. Its connectivity options allow flexible deployment in projects requiring interoperable building blocks. Shelly Smart Control can be used for management and supervision when available within the project scope.

Use and applications

As a relay with dry contact, it switches circuits and enables on/off control of lighting or auxiliary loads inside control panels. It fits technical projects where reliable control and clear integration paths are required, supported by Wi‑Fi for remote operation and Bluetooth for local configuration. The DIN rail form factor helps streamline assembly within electrical boards and modular enclosures.

Operational requirements include mains voltage within the specified range and track mounting in a suitable enclosure. Commissioning is simplified by Bluetooth for initial setup, while Wi‑Fi enables ongoing management through the defined application layer. This combination supports practical deployment in connected installations without altering existing circuit topology thanks to the dry contact interface.

Key benefits

• Streamlined project integration thanks to Wi‑Fi and Bluetooth connectivity.
• Clean on/off control by means of a dry contact relay interface.
• Efficient panel assembly due to DIN rail mounting and compact dimensions.
• Consistent remote oversight through integration with a dedicated app.
• Flexible commissioning facilitated by local Bluetooth configuration.
