Expert Net Control 2312-1

Remote I/O System with 3 switchable relay outputs and energy metering for DIN-rail mounting

Expert Net Control 2312-1 allows remote controlling over TCP/IP networks. The device disposes of 3 individually switchable relay ouputs. All outputs dispose of two energy meters each, metering various electrical dimensions. The sensor interface allows monitoring of ambient temperature and humidity by optional available sensors.

Expert Net Control 2312-1 is easily mounted on DIN rail and enables remote controlling and monitoring of ICT installations in less than no time.
