The module MR-SM3 is a smart meter component for building automation. Current, voltage, power and many other values can be captured by three 230 Volt current circuits. In addition, the device provides monitoring functions of for example asymmetry, phase failure, phase sequence, overvoltage and undervoltage. These values can be queried via a Modbus-Master. Module address, bit rate and parity are set with two rotary switches on the front or by software. Suitable for decentralized mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.
