7. Structural Characteristics

1. Overall integrated finished cable split into three fixed structural partitions: left-end D-SUB connector assembly, middle continuous multi-layer shielded cable main body, right-end D-SUB connector assembly, all connection positions fixed via injection molding strain relief structure without loose separation.
2. Internal three groups differential twisted pairs are independently wrapped with aluminum foil shielding respectively before overall copper mesh outer shielding wrapping, forming dual-layer hierarchical shielding structure for each signal channel.
3. Both terminal D-SUB 37P connectors reserve dedicated metal grounding tab extending outward from shielding shell for convenient fixed PE grounding construction on cabinet ground bus bar.
4. Outer jacket surface continuously printed with white ink fixed model code 9000-025, factory production batch number and safety certification mark at equal spacing intervals along cable length direction.
5. Connector side shell reserves small rectangular locking hole for installing fixed locking screw to lock D-SUB plug onto chassis TriBus socket and prevent loose dropout from equipment vibration.
6. Cable main body maintains circular uniform outer diameter after finished processing without local bulging or concave deformation, guaranteeing neat cabinet wiring bundling arrangement.

8. Working Principle

1. After two D-SUB terminals separately plug into master chassis TriBus interface and expansion chassis TriBus backplane socket, connector internal gold-plated pins complete electrical docking with chassis backplane bus contact terminals to build full physical TriBus transmission link.
2. Three groups internal independent differential twisted pairs separately transmit A/B/C three redundant channel digital data defined by Tricon TriBus protocol between master controller MP modules and remote expansion I/O modules.
3. Master chassis three main processors synchronously transmit sampled field input data via this cable to expansion chassis I/O circuit, meanwhile expansion chassis uploads real-time channel fault diagnostic information back to main controller through opposite-direction TriBus signal transmission.
4. Double-layer full shielding structure of cable absorbs external industrial electromagnetic interference pulse introduced by cabinet internal high-power equipment, preventing differential signal distortion and TriBus communication frame loss during high-speed data transmission.
5. Connector metal shielding shell is connected to cabinet PE ground bar via reserved grounding tab to lead stray induced interference current into protective earth and stabilize bus reference potential.
6. The cable keeps three redundant channel signal transmission synchronism required by TMR architecture, supporting system to complete three-out-of-two voting logic calculation at controller side to shield abnormal error signal from single faulty chassis channel.

6. Cable bending constraint: Minimum allowable static bending radius of cable main body is 8 times cable outer diameter; sharp-angle forced bending less than specified radius is prohibited during routing fixation.
7. Post-installation space constraint: Keep cabinet cable channel ventilation unobstructed without heavy component compression and extrusion on cable outer sheath surface.

13. Usage Precautions

1. Electrostatic protection regulation: Wear certified anti-static wristband reliably connected to cabinet PE ground bar when plugging/unplugging D-SUB connector; bare-hand direct contact with exposed connector gold-plated pins is strictly forbidden to avoid electrostatic damage to chassis backplane TriBus circuit chip.
2. Live operation restriction: Cut off full SIS control cabinet total DC/AC input power completely before cable disassembly and replacement; live hot plugging of TriBus D-SUB connector during system normal running state is prohibited.
3. Daily maintenance specification: Clean cable outer surface accumulated floating dust every twelve months with dry compressed air at maximum 0.2MPa air pressure; avoid high-pressure air direct blowing into D-SUB connector internal pin gap position.
4. Mechanical load constraint: Prohibit heavy object compression, pulling and over-tight bundling of cable main body; sharp metal edge scratch contact with cable outer jacket is forbidden during cabinet daily overhaul operation.
5. Spare cable storage standard: Store unused spare cables inside original factory anti-static sealed plastic bag under 18℃~26℃ dry constant-temperature warehouse environment, far away from corrosive chemical solvent and high-temperature heat source storage area.
6. Fault disposal criterion: Immediately replace defective cable once TriBus communication frame loss, intermittent signal dropout occurs during system operation; unauthorized peeling off cable outer jacket and modifying internal core wire wiring layout are prohibited, purchase original factory 9000-025 spare part for direct replacement maintenance.
7. Long-term idle equipment management: If SIS safety cabinet keeps continuous shutdown over 90 consecutive days, loosen D-SUB connector locking screw and separate cable plug from chassis socket; store detached cable inside sealed moisture-proof spare part storage box to prevent connector pin oxidation corrosion.
