Shelly Pro 1 DIN Rail Dry-Contact Relay

Shelly Pro 1 is a DIN-rail, one-channel smart relay with potential-free contacts for professional automation installations. The dry-contact output is useful when the controlled circuit must remain electrically isolated from the device supply, subject to the published switching limits. Shelly documents LAN, Wi-Fi and Bluetooth connectivity, an embedded web interface, schedules, webhooks and scripting support. The single output is rated at 16 A. Its switch inputs support local control, while the Pro enclosure provides a compact DIN-rail format for a distribution board or control cabinet. This model is a switching relay without integrated power metering, so energy measurement requires separate equipment if needed. Confirm load type, isolation, circuit protection and terminal wiring before installation. Have a qualified electrician install mains-connected equipment.
