DJGZ-ZTY666 Data Concentrator
DJGZ-ZTY666 data concentrator which forms part of a remote management system with automatic meter reading through power line communication (PLC) or RF mesh, communicating with the system via GPRS or Ethernet. The concentrator is the intelligent monitoring terminal for transformer backend distribution network monitoring.
◆ The data transmission is in accordance with DLMS/COSEM protocol.
◆ Support various PLC solutions like G3/Prime/S-FSK.
◆ Support multi-interface communication, one RS232 interface, two RS485 interfaces, one infrared interface, one RJ45 interface, one DC analog quantity interface, two access interfaces for state quantity, one GPRS communication module, and one PLC communication module.
◆ Support energy measurement, class 1 for active accuracy and class 2 for reactive accuracy.
◆ Support automatic supplementary meter reading function, concentrator will automatically read the data which don’t read in the specified time.
◆ Support data management function, concentrator can store daily freezing data, freezing data monthly, freezing data of meter reading days,24 energy data on the hour of 10 days for 10 key users and events log.
◆ Support convenient maintenance function, local parameters can be set through infrared interface, program update, program backup, parameters set and parameter backup can be achieved by USB.
◆ Support remote firmware upgrade function，concentrator can be upgraded by GPRS network or HTTP.
