HDCU-800::Microcomputer Communication Manager


HDCU-800 series communication management machine adopts advanced embedded processor and communication technology, Can quickly to Constitute flexible networking for intelligent protection and control device of substation, power plants and industrial and mining enterprises. Collect remote signal / telemetry / electrical degree / alarm information / setting parameters / recorder data, To the background monitoring system or Forwarded to the scheduling system far away, and to all the intelligent protection and control device transmits issued background monitoring system on the network command, two-way communication implementation and monitoring system.


  • Overview
  • Characteristic
  • Selection Guide


  • Communication Interface Function2 RS232 ports, 4 ~ 16 RS485 interface, 2 CAN interfaces, 1 ~ 4 Ethernet interface
  • Upload DataTelemetry, remote communication, data of telesignalisation displacement event information, action protection message to the background monitoring system of protection and monitoring device.
  • Data TransferMessage send background monitoring system (such as inspection, remote control, check the settings, modify the setting value, the distance reversion, timing etc.) to the protection and monitoring device.
  • Variety Of Protocol Conversion FunctionThe downlink channel support: Ministry of CDT, Modbus, IEC60870-5-103, IEC60870-5-104, DL645, from the 94 protocol. The uplink channel support: CDT, Modbus, IEC60870-5-101 department, Sc1801.
  • Dual Redundancy FunctionDouble communication management machine running at the same time to monitor the running status of each other. The main communication management machine in normal operation, automatic backup state in preparing the communication management machine. The fault of communication management machine, automatic switching communication management machine replacement operation. To restore the fault of the main communication management machine, automatic switching back to the communication management machine operation, preparing the communication management machine backup status. In the communication management machine backup state cannot be sent out data.
  • Time Setting FunctionReceive GPS time of correct signal. Double management machine system, management configuration GPS automatic machine is not configured GPS to management of the school. According to the protocol of receiving, from the specified channel to the designated channel transmit clock information.
