Technical Specifications:
  • Communication Method: High-speed serial communication (non-fiber, serial bus)
  • Communication Rate: Up to 10 Mbps (typical)
  • Communication Protocol: GE Fanuc proprietary DS3800 protocol
  • Connector: High-speed serial connector (RJ-45 or dedicated interface)
  • Operating Temperature: 0°C to 60°C
  • Operating Humidity: 5% to 95% (non-condensing)
  • Power Supply: Backplane bus +5V DC
  • LED Indicators: Power (green), Data Transmit/Receive (green), Fault (red)
Functional Features:
  • Provides high-speed deterministic serial communication channels
  • Supports redundant communication link configuration
  • Features real-time link quality monitoring
  • Supports online diagnostics and status reporting
Material Composition:​ Multilayer FR-4 PCB with high-speed signal impedance matching design; GE dedicated high-speed serial communication ASIC; metal-shielded RJ-45 or dedicated high-speed interface connector; galvanized steel enclosure with EMC shielding treatment.
Structural Features:​ Standard DS3800/Mark VIe module dimensions; front panel with communication status LED group; rear backplane with system bus connector and serial communication interface; module locking mechanism.
Working Principle:​ Controller-side data is sent to the module via the backplane bus. The onboard ASIC converts parallel data into high-speed serial data streams, which are transmitted via the serial interface to the remote I/O-side receiving module, and vice versa, enabling bidirectional high-speed data exchange.
Application Scenarios:​ Gas turbine Mark VIe control; large DCS distributed I/O architecture; power plant auxiliary system control; petrochemical process control.
Installation Requirements:
  • Install in the designated slot of the Mark VIe rack DS3800 subsystem
  • Serial communication cables must use shielded twisted pair or coaxial cable
  • Cable length shall not exceed 100 meters (typical, depending on rate)
  • Terminal resistors must be configured according to communication protocol requirements
Usage Notes:
  • Communication cables must be kept at least 30 cm away from high-voltage power cables
  • System redundant switching must be performed before replacing modules
  • Communication bit error rate should be checked regularly
