DIN‑mount dual relay module Shelly 2L Gen3, 2 channels, Wi‑Fi/Bluetooth, 220–240V AC, 50Hz, plastic housing

Shelly 2L Gen3 is a DIN‑mount dual relay module with two independently controlled channels for switching appliances on 220–240 V AC (50 Hz). It supports Wi‑Fi (802.11 b/g/n) and Bluetooth connectivity, programmable scripts and webhooks, intelligent on/off control, sunrise/sunset scheduling and built‑in overheat protection. The module comes in a compact plastic housing with dimensions 42×37×16 mm and low power consumption (max 1.2 W), suitable for installation on DIN rails in electrical cabinets for lighting or home automation tasks.

Advantages

The device offers two separate channels for independent control of loads, remote operation via Wi‑Fi and Bluetooth, and support for automation through scripts and webhooks. Intelligent on/off logic with sunrise/sunset scheduling helps adapt switching to natural light cycles, while overheat protection increases operational safety. Its compact plastic housing and low standby power consumption make it convenient for space‑constrained DIN‑rail installations.

Suitable for

• Controlling lighting circuits in residential or small commercial electrical panels
• Switching household appliances and loads up to the relay rating
• Integrating into home automation systems using Wi‑Fi, Bluetooth, scripts or webhooks
