Data Concentrator Automatic Meter Reading System Three Phase Power Supply GPRS
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.
Main Features
1) GPRS uplink with head-end server (HES)
2) Alternative com port :IR optical and RS485
3) On demand and scheduled meter readout
4) Remote load control overriding the consumers
5) Non-volatile memeory for data retention
6) IEC 62056-21 and DLMS/COSEM compliant
7) Automatic fault alarm to HES
Utility benefits
1) High capacity for a hub of up to 500 pcs sub-meters
2) Surge protection and low voltage operatable
3) Quick and easy to install
4) Low operational and maintenance cost
5) Remote tariff setting, time synchronization with meters
6) Long life time design with easy upgrade features
