 | UT-TXJ3 Communication Management Unit  (click:1012)
      The UT-TXJ3 communication management unit is the communication hinge among different intelligent devices in substations. Through it the protocol conversion and data exchange between devices is achieved, the telesignaling and telemetering signals transmitted to the main station, and meanwhile various telecontrol signals from the main station will be retransmitted to sub-station devices.

  ■ It has good stability by using embedded real-time multi-task operating system;
  ■ 19-inch standard case convenient to be grouped into one panel
  ■ Component-based structure design with any component supportting hotplug enables the system to be maintained with power on and improves its mean time between failures;
  ■ Support multiple network structures (including RS232 start network, RS422/RS485 bus network and Ethernet), up to 48 series ports and 4 Ethernet ports;
  ■ Support protocols such as IEC61850, IEC 60870-5-101/103/104, and other open communication protocols of the major integrated automation manufacturers;
  ■ Dual-power redundancy makes the operation more stable;
  ■ Full Chinese operation interface and network debugging function makes configuration, debugging and maintenance convenient and fast;
  ■ “5-prevention” logic judgement function can effectively prevent misoperation that occur in the local monitoring system or the remote control center;
  ■ Operation recording function enables user to retrospect the operation to device;
  ■ Online self-diagnosis and fault tolerance function: each functional component is able to carry out fault repair by itself, and for the fault that can not be repaired a fault prompt will be given;
  ■ GPS clock synchronization;
  ■ Support WEB function;
  ■ Support FTP transmission.
