Concentrator

Product ID.：WL111B

Communication mode：GPRS/EDGE/WCDMA/Ethernet（Uplink），RF/PLC(Downlink)

A smart grid terminal product of advanced technology, stable performance and reliable operation. Based on Linux operating system, W110A adopts mature GPRS/EDGE/WCDMA/Ethernet communication technologies to build uplink data link. External module is plug-and-play.Manage data collection, data storage, data processing, monitoring and management of metering terminals or other devices. It is the central device to connect the master station system and can perform relevant functions including data pass-through.

  • Main Functions
  • Technical Parameters
  • Communication channel adopts high-speed full duplex industrial GPRS/EDGE/WCDMA/Ethernet module; support TCP wireless network communication method;
  • Adopt modular design and support hot plugging; no need for any manual setting after the module is replaced; the terminal can automatically recognize wireless module and log in by itself;
  • Support protocols of communication with the master station: “Q/GDW 376.1—2013 Communication
  • Protocol between Power Consumption Information Collection System with Collection Terminals” and DLMS protocol;
  • Support protocol of communication with meters: DL/T645-2007 and DLMS protocol. Extend and add protocols in line with field needs after upgrading the protocol database of main station;
  • Support online upgrading of local/remote software; support local/remote modification of concentrator and meter parameters, and read terminal and meter data.
  • Excellent electromagnetic compatibility, resistant to interference of high voltage spike pulse, intense
  • magnetic field, strong static, and lighting surge; high temperature self-adaption range;
  • Three phase power supply; terminal can work normally when any two phases of the three phase four wire interrupts;
  • Terminal can keep data, maintain clock chip work and report outrage event in case of losing AC power supply;
  • Low power consumption: overall power consumption is no more than 10W when it is not communicating with the main station. In case of data communication, overall power consumption is less than 15W.
