Model Interpretation

51400700: Base material code for the card; -100: Hardware version number; Belongs to the TDC3000 LCN rack communication series. Technical Specifications

LCN bus + Data Hiway dual-bus architecture; Backplane 5VDC system power supply; Operating temperature: -25℃ to +70℃, humidity: 5% to 95% without condensation; Total machine net weight approximately 520g; Data Hiway transmission rate 250Kbps, LCN bus rate 5Mbps; CE and UL industrial certifications; Supports redundant rack configuration.

Interface and communication configuration

Gold finger on the rear connects to the LCN main control rack backplane; Onboard LCN bus interface connects to the system local area network; Front aviation terminals lead out the Data Hiway coaxial communication cable; Three status indicator lights on the panel: RUN, COM, and FAULT, providing real-time feedback on bus communication failures. Core function

LCN and Data Hiway protocol conversion, data forwarding; self-check for bus link failure and alarm to the upper computer; short-circuit isolation protection for communication link; single segment bus failure does not affect the operation of the entire machine; supports hot-pluggable replacement of LCN rack while powered on. Applicable scenarios

Replacement of the old system TDC3000 Data Hiway bus gateway in petroleum refining, thermal power generation and chemical industries, and expansion and renovation of the control system.

Operation and maintenance instructions

Data Hiway is wired using dedicated coaxial shielded cables, which are kept away from frequency converters and power cables; coaxial connectors should be tightened regularly to prevent moisture and oxidation; conduct quarterly inspections of panel indicator lights to check for faults; perform bus communication verification before installing spare parts, and clean and prevent moisture in corrosive conditions on a regular basis.
