Modular RTU unit for smart grids, distribution network and substation automation and advanced industrial automation tasks.

Based on SMC 133 analyzer but modified to needs for RTU7M modular remote terminal unit. Thanks to the high integration of analyzer, resulting setup of RTU and analyzer is always most compact. Solution is targeted for many different applications which needs combination of automation, control and accurate monitoring of energy, power quality evaluation and fault recording. Compactness and flexibility of this solution allow deployment not only in new projects but is suitable also for retrofit.

RTU7M system usually contains power supply unit, processor and communication module/card and up to 15 other expansion cards. Different kinds of communication options such as RS-485, fast Ethernet, 3G and 4G (LTE) cellular modem and other options are available. Cards providing various kind of auxiliary power supplies with or without backup or cards with analog or binary inputs and outputs are also present. The controller module provides all information and values over a wide range of interfaces and protocols, such as IEC 61850, IEC 101, IEC 104 or Modbus. For measuring of multiple feeders it’s possible to use multiple SMC-RTU7M cards in one RTU7M unit.
