III. Main Functions

DCS card ↔ FTA terminal board signal interconnection

Transmission of 4–20mA analog quantity, 24V digital quantity, system power supply, and shielded ground

Double-layer shielding, significantly reducing signal drift/jump caused by interference from frequency converters, large motors, etc. in the field

Original factory standardization, no need for debugging or jumper wires

Standard 40-pin definition, direct replacement of old cables, fully compatible with the original system

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

Suitable for all series of I/O cards

C series I/O: C200 / C300

PM I/O: TPS / TDC3000

General compatibility for AI/AO, DI/DO, pulse card, and communication card

High reliability and long lifespan

Industrial-grade material, resistant to bending, vibration, and aging

Flame-retardant, low smoke, meeting the fire safety requirements of the control room

No signal attenuation or contact failure during long-term operation

IV. Typical Application Scenarios

Petrochemical industry: I/O card in the DCS control cabinet connected to the FTA terminal board (2m is the most commonly used cabinet length)

Power (thermal power / hydropower): Analog quantity / digital quantity signal wiring in PKS/TPS system

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

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

System expansion / renovation: Replacement of old system spare parts, connection of new I/O station

V. Installation and Wiring Tips

Installation location: Horizontal / vertical laying in the control cabinet, away from frequency converters, transformers, and high-power contactors (≥ 20cm)

Wiring: Avoid excessive bending, dragging, and squeezing; bending radius not less than 8× outer diameter

Connectors: Insert straight into the slot, and hear the "click" sound to indicate locking;严禁 hard insertion， crooked insertion， or forced twisting

Shielding grounding (key)： Single-ended grounding of the shielding layer (FTA side)， floating on the card side；严禁 grounding at both ends， to avoid forming ground circulation interference

VI. Maintenance and Fault Troubleshooting

Daily maintenance

Quarterly： Check connector tightness， outer skin wear， bending deformation

Annual： Insulation resistance test， shielding continuity check， connector oxidation check

Common faults

Signal jump / drift： Shielding damage， poor grounding， too close distance to power lines

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

Breakage： Excessive bending， squeezing， rat bites
