DJGZ32-RDK15 intelligent data concentrator is one important part of AMI system. It connects with master station as a gateway for communication between the meters and the HES. It can perform task setting, data collection, data transmission and data storage, meter management, and task execution .
The upper communication between data concentrator and master station employs GPRS or RS232 technology; the Down link communication between data concentrator and the meters employs RS485/PLC communication.
