The PMC-5231, is an Industrial IoT Power Meter Concentrator. Designed with a user-friendly and intuitive web site interface that allows users to implement the Energy monitoring and management system just a few clicks away; no programming is required. It easily integrates with the ICP DAS power meters via RS-485 or Ethernet interface. It equipped with functions such as: measuring power consumption of the devices, energy usage analysis, power demand management and alarm notification. The PMC-5231 features a built-in Micro SD card, allowing the power data to be saved in a data log file, and automatically send back the data log files to the back-end management center for data analysis and statistics.

PMC-5231 supports the Modbus TCP/RTU, SNMP, FTP and MQTT protocols for seamless integration with the back-end SCADA/MES/IT/IoT/Network Management systems. Allowing the user to monitor the status of power consumption of each device and perform statistics and analysis of the power information. The PMC-5231 is a perfect concentrator of power meter in the Energy monitoring and management application of Industry 4.0 age.
