The METSEDM2355S is a digital multi - function relay. It can measure voltage, current, power, and energy in 3 - phase systems. The voltage measurement range is typically 400V AC, and it can be used with CTs for current measurement up to a significant value, like 800A. It offers protection functions such as over - current protection, under - voltage protection, and over - power protection. The relay has 3 digital inputs for receiving external signals, such as switch status or control commands, and 2 digital outputs for controlling external devices or sending alarms. It communicates via Modbus RTU over an RS485 interface. The power supply for the relay is 24V DC. It can operate in a temperature range of -5°C to +55°C and has an IP20 protection rating, suitable for installation in standard industrial control panels.
