Dual-Channel Smart Relay with Power Metering
Shelly Pro 2PM is a DIN rail mounted smart relay offering two independent channels, each rated for up to 16A with a combined capacity of 25A. It integrates LAN, Wi-Fi and Bluetooth connectivity for local and remote control. Integrated power metering on both channels provides real-time energy monitoring for connected circuits. The unit installs directly inside breaker panels without additional wiring.
Fits Standard DIN Rail Panels
The relay mounts on a standard DIN rail inside an electrical enclosure, requiring a suitable panel and power supply. Its three wireless interfaces connect to existing networks, removing the need for a separate gateway hub. Local scripting and scene support free up cloud dependency for latency-sensitive automations. Compatibility with Google Home, Alexa and the Shelly app allows voice and mobile control alongside other Shelly devices.
Suits Installers Automating Lighting.
This relay suits electricians and system integrators adding smart control to single-phase loads such as lighting, motorised blinds, awnings or parking barriers. Built-in thermal, surge and over-voltage protection supports safe operation in residential and commercial panels. Buyers needing three-phase switching, higher per-channel current or a different mounting format should look at alternative devices.

Questions about this item
How much current can each channel handle continuously before the relay hits its per-channel limit?
Each channel is rated for up to 16 A, with a combined device limit of 25 A, so the per-channel ceiling is reached first when a single load exceeds 16 A.
What thermal or noise behaviour should be expected when the relay runs at high load all day?
The unit has built-in overheating protection and no moving parts, so it operates silently and will throttle or shut down if internal temperatures rise beyond safe limits.
What electrical infrastructure must already be in place for this DIN-rail relay to function?
A single-phase supply with a compatible DIN rail in the distribution board and neutral connections for each controlled circuit are required for installation.
