The DZ9 device enables the transmission of up to 8 independent protection commands over different digital communication channels and up to 4 independent protection commands over analog communication channel. Channel coding and adaptive command detection algorithms are ensuring the optimal combinations of the transmission time, security and dependability in the current transmission conditions.

Complete configurability and modularity of the DZ9 device offers users to adapt the device easely and in user-friendly way to the control systems requirements and to the characteristics of the transmission media.

Main features

  • Digital line interfaces (E1, G.703.1 co-directional 64 kbps, Direct Fibre Optic, IEEE C37.94)
  • Analog line interface
  • One power supply unit covering input voltages from 40 V DC to 320 V DC and from 82 V AC to 264 V AC
  • Optional auxiliary power supply module replaceable during operation
  • Redundant communication channel
  • Multi-point command transmission
  • Fast command transit function
  • Programmable matrix of command inputs and outputs
  • Channel identification preventing network switching errors
  • Optional signalling front panel displaying command counters and main device control signals
  • Synchronization with external GPS
  • Synchronization acording to SNTP
  • Management and supervision via LAN/WAN or RS232 connection
  • SNMP agent

 

Applications

  • Point-to-point connection scheme with one line unit - basic and low-price solution
