  • As Power Utilities locations are remotely distributed, DCS is usually implemented in power plant automation system for increasing working productivity as well as for smart energy production with eliminated influence on environment.

  • Vital role of data communication between various automation components is evident though it brings the problem of data protection from cyber-attacks and network redundancy as it is based on Ethernet and Internet.

  • DP612 features IP31 rugged enclosure, dual redundant 10~60VDC power input, Hi-pot isolation and operating temperature -40~75°C to ensure overcoming high level of electromagnetic interference on power plants.

  • 8 Gigabit Ethernet copper ports can be connected with IP surveillance cameras whilst 4 Gigabit SFP Combo ports are used for uplink data transmission to Control Center.

  • VRRP function provides gateway backup, keeping network avaliable.
