A relay controller and energy meter combining load switching, energy monitoring and power measuring in a single device.
The Genius 4CH combines measuring and switching load in a single device. Communication with any third-party system runs via the Modbus RTU/ASCII protocol over an RS-485 interface. It provides four bistable relay interfaces in single-pole/single-throw configuration, plus manual switches for service overrides — a modular basic solution for controlling lighting installations. Mounts on standard 35 mm DIN rails or via a key hole in the housing base; AC line powered.
