Two-Channel DIN Rail Relay
The Shelly Pro 2 is a professional two-channel relay designed for DIN rail mounting inside breaker panels. It provides potential-free dry contact outputs rated up to 25A for controlling lighting circuits, motorized valves and power outlets. Connectivity includes LAN, Wi-Fi and Bluetooth for integration with home and commercial automation systems.
Suited for Professional Automation Installers
This unit fits electricians and facility managers who need independent two-phase circuit control with local scheduling and script support. It is not for buyers who require energy monitoring data on each channel. It is also not for projects needing more than two switched outputs or a higher current rating than 25A.
25A Dry Contact Rating
The decisive specification is the 25A potential-free contact rating, which determines the maximum load each channel can switch safely. This ceiling defines whether the relay can handle your specific lighting, heating or appliance circuits without additional contactors.

Questions about this item
How do I verify the Shelly Pro 2 is working correctly after wiring it to the DIN rail and connecting loads?
Power the unit, confirm the status LED shows a network connection, then use the mobile app to toggle each of the two channels and observe the connected lights or valves respond instantly.
What accessories are included with the Shelly Pro 2 and what must I purchase separately for installation?
The relay module itself is supplied; you will need to source DIN rail mounting hardware, appropriate gauge wiring for up to 25A circuits, and any motorised valves or lighting contactors you intend to control.
Which version of the Shelly Pro 2 should I choose for a two-phase lighting circuit rated at 25A?
The single model listed is a two-channel, two-phase relay rated at 25A, so it matches that requirement directly.
