Blebox switchboxD DC DIN 2-Channel WiFi Relay Module with Energy MeterBlebox switchboxD DC DIN 2-Channel WiFi Relay Module with Energy MeterBlebox switchboxD DC DIN 2-Channel WiFi Relay Module with Energy MeterswitchboxD DC DIN Blebox is a compact two-channel relay module designed for installation in an electrical distribution board on a 35 mm DIN rail. With a housing width of only 17.5 mm, it combines wireless control, configurable relay outputs, logical inputs and integrated energy measurement in a space-saving design.

The module is supplied with 230 V AC and features two relay outputs that can be configured to operate independently or in a mutually interlocked mode. This allows the connected circuits to be controlled according to the selected operating configuration.

Key features

Two relay outputs with a maximum load of 5 A per output

Maximum resistive load of 2 × 1150 W at 230 V AC

Motor load according to AC3: 2 × approximately 0.15 kW at 240 V AC

Two opto-isolated logical inputs supporting 12–230 V AC/DC

Support for momentary and bistable switches, including traditional and two-way configurations without backlighting

The integrated energy measurement function covers a range from 0 to 2300 W with a resolution of 1 W. The module provides current readings, total consumption for a selected period and automatic calculation of the cost of consumed energy. Measurement history is available online with a 5-minute resolution, with measurements provided jointly for both outputs.

Wireless control and connectivity Control is provided through µWiFi technology, compatible with WiFi 802.11g in the 2.4 GHz band. The module can be connected directly in Access Point mode or through a standard WiFi router. Remote access is available from any location with Internet access. Communication is bidirectional and encrypted, and an open API is available at technical.blebox.eu.

The built-in tact-switch button enables local switching of the outputs on and off, while colour illumination on the housing indicates the device status. The module can be operated using Apple iPhone, Apple iPad, iPad Mini, Android devices and computers or mobile devices supporting HTML5.
