DJGZ23 - ZTY666 type concentrator (hereinafter referred to concentrator) is Zhejiang Chint instrument Co., LTD., on the basis of the state grid construction power user electricity information acquisition system request, unifies design, development and field service experience in the electric power industry for many years, based on the embedded software and hardware platform design of a new generation of centralized meter reading equipment. Concentrator can collect collector or meter data, and carry on the processing and storage, At the same time, it can exchange data with master station system and hand terminal.

Product features:

• Uplink channel: support RJ45 Ethernet interface, RS485 or GPRS communication interface (optional). It can exchange data directly with master station management system.

• Downlink channel: support 1 road RS485 communication interface, 1 road power line carrier communication interface, 1 road DC analog interface.

• Local interface: support 1 road RS232 communication interface, 1 road USB interface, 1 road RS485 communication interface, 1 road infrared communication interface.

• Load capacity: RS485 interface probable maximum load and only watt-hour meter data acquisition. The power line carrier communication interface maximum can load 1000pcs data collection, carrier channel support the United States Echelon, Qingdao Eastsoft, Qingdao Topscomm and so on mainstream manufacturers carrier chip.

• AC sampling function: active accuracy level: class 1, reactive accuracy class 2 (only as assessment reference use).

• Field maintenance function: It can set the parameters for maintenance work by RS485 communication interface, RS232 communication interface or infrared communication interface, also can copy and read data in site.

• Data acquisition function: Can be classified collection of electric energy meter data, acquisition of data types including total and tariff data, voltage current instantaneous flow data, maximum demand data, etc. If can’t collect data within the prescribed time, it can fill copy automatically.

• Data management function: according to the setting of the Lord, it can store each meter 31 days zero (next day the zero) freeze power data, 12 month zero (monthly 1 zero) freeze power data, 12 meter reading, frozen data, 10 key users 10 days of 24 integral point electrical energy data, as well as an important events, article 256 article 256 general event log.

• Monitoring function: it can record the electric energy meter running status, when in the condition of the meter parameters change, clock out-of-tolerance or meter failure and so on, it can generate events , record happen time and abnormal data.

• Support remote or local online upgrade function: It supports remote upgrade breakpoint continuingly way, if a program upgrade is not successful, the concentrator can be made according to the original procedures operation; Also can use the U dish to backup local program updates, program, parameter setting, parameter.

• Deal with incident report function when power off: when concentrator power down, built-in battery of the concentrator will supply power, and report power failure events.
