III. Main Functions

Signal transmission between DCS modules ↔ FTA terminal boards

Connecting I/O cards of PKS/TPS/TDC3000 to the field wiring terminal boards (FTA)

Transmitting 4–20mA analog, 24V digital, power supply, and ground

Double-layer shielding, anti-EMI/RFI, reducing signal drift caused by on-site interference

Standardized, plug-and-play

Original factory standard pin definitions, no need for debugging or jumpers

Integrated injection molding connectors at both ends, preventing loosening and incorrect insertion

Direct replacement of old cables, fully compatible with the original system

Adapting to the full range of I/O cards

C series I/O: C200/C300 system

PM I/O: TPS/TDC3000 system

All types of analog AI/AO, digital DI/DO, pulse cards, and communication cards can be adapted

High reliability, stable operation over the long term

Industrial-grade material, resistant to bending and vibration

Flame-retardant, low smoke, meeting fire protection requirements in the control room

No signal attenuation or contact failure during long-term operation

IV. Typical Application Scenarios

Petroleum industry: I/O cards in the DCS control cabinet connected to FTA terminal boards

Electricity (thermal power / hydropower): Analog/digital signal wiring in PKS/TPS systems

Papermaking / pharmaceuticals / water treatment: Signal transfer between the control room and on-site instruments

Metallurgy / cement: Stable signal transmission in high-temperature, high-dust control cabinets

Factory automation renovation: Replacement of old systems, expansion, spare parts replacement

V. Installation and Wiring Tips

Installation location: Horizontal / vertical laying in the control cabinet, away from high-power transformers, frequency converters

Wiring:

Keep ≥20cm distance from power cables

Avoid excessive bending, dragging, and squeezing

Connectors:

Insert straightly into the slot, and hear the "click" sound to indicate locking

Do not hard insert, crooked insert, or force twist

Shielding grounding:

Single-ended grounding of the shield layer (FTA side), floating on the card side

Avoid forming ground circulation at both ends

VI. Maintenance and Fault Troubleshooting

Daily maintenance

Quarterly: Check connector tightness, wear, bending deformation

Annual: Insulation resistance test, shielding continuity check

Common faults

Signal jump / drift: Shielding damage, poor grounding, parallel with power lines

Contact failure: Loose connector, oxidation of pins, long-term vibration

Breakage: Excessive bending, squeezing, damage from mice
