  • Technical Specifications:
    • Communication Interfaces: 2 × RJ-45 Ethernet ports (dual-port)
    • Communication Rate: 10/100/1000 Mbps auto-negotiation
    • Protocols: TCP/IP, Modbus TCP, GE SRTP (proprietary)
    • VLAN Support: Yes (IEEE 802.1Q)
    • Maximum Connections: 64 TCP connections
    • Buffer: 64 KB transmit/receive buffer
    • Power Supply: +5 V DC (backplane powered)
    • Operating Temperature: -20°C to +60°C
    • Protection Rating: IP20 (installed inside cabinet)
    • EMC Certification: CE, FCC Class A
  • Features:​ Dual-port design supporting network redundancy (active-standby automatic switching); built-in network switch function for cascading multiple devices; VLAN partitioning for network isolation and security management; built-in firewall filtering illegal access; supports SNMP v2/v3 network management protocol; front panel LED status indicators (Link, Activity, Fault).
  • Material & Structure:​ Housing: aluminum alloy with black anodized finish; network interfaces: shielded RJ-45 metal connectors with built-in ferrite bead filtering; PCB: FR-4 six-layer surface mount design; Euro-card standard size; front panel: 2 RJ-45 ports + 4 LED indicators; rear: 48-pin backplane connector.
  • Working Principle:​ The controller CPU sends data to the module, and the Network Processing Unit (NPU) inside the module encapsulates the data into Ethernet frames (IEEE 802.3) and transmits them through the RJ-45 interface to the switch or host computer.
  • Application Scenarios:​ Network interconnection between Mark V turbine control systems and host systems in industries such as gas turbine control (GE 9FA/7FA/6FA, etc.), steam turbine control, petrochemical DCS control, and power generation automation.
  • Installation Requirements:​ Install in the designated slot of the Mark V controller rack; ensure proper grounding connection; operate in a cabinet environment with IP20 protection.
  • Usage Notes:​ Do not plug or unplug the network cable during system operation to avoid network interruption; regularly check LED status to confirm communication health.
