DIN-rail mountable smart relay with 2 dry-contact outputs (16 A each, 25 A total), WiFi/LAN/Bluetooth, hub-free automation and scripting for lights/appliances.The Shelly Pro 2 is a professional-grade, DIN-rail mounted dual-channel smart relay built for controlling lighting circuits, appliances, irrigation valves and general-purpose loads in residential and commercial panels. Each channel supports up to 16 A, with a combined device limit of 25 A, and uses potential-free dry contacts — giving you flexibility to switch different voltage types safely. It supports WiFi, LAN (Ethernet) and Bluetooth, allowing full local control through the built-in web interface and cloud-free automation. For advanced integrations, it offers MQTT, HTTP/HTTPS webhooks, scripting (mjS) and KNXnet/IP, making it suitable for everything from smart-home setups to BMS environments. Safety features include over-temperature, over-power and over-voltage protection, along with a V-0 flame-retardant enclosure for reliable panel-mount installation. The compact 94 × 19 × 69 mm design fits standard DIN rails and supports conductors from 0.5–2.5 mm². With two independent outputs, robust connectivity and pro-grade safety, the Shelly Pro 2 provides installers and integrators a flexible and secure solution for multi-circuit smart control.
