Length Comparison of the Same Series:

001: 1m

002: 2m

003: 3m (This model)

004: 4m

010: 10m

015: 15m

020: 20m

II. Technical Parameters (Consistent with the electrical specifications of 001/002, only the length is different)

1. Electrical

Signals: Analog 4–20mA / 0–5V, 24V DC, digital quantity, power supply, shielded ground

Conductor: 24 AWG multi-strand tin-plated copper

Insulation: Flame-retardant PVC/XLPE

Voltage withstand: 300V AC

Shielding: Aluminum foil + copper braided double-layer shielding (100% coverage), anti EMI/RFI

2. Mechanical and Environmental

Length: 3 m (±2%)

Outer Diameter: Approximately 8–10 mm

Bend Radius: ≥ 8× Outer Diameter

Temperature: -20℃ ~ +70℃

Flame Retardant: VW-1 / FT2

Protection: IP20 (in control cabinet)

3. Connectors and Pins

One end: DCS I/O module plug (C series / PM I/O)

The other end: FTA terminal board-specific plug

Core Number: 40 standard I/O bus

Compatibility: Fully consistent with the entire MU-KFTA series, plug-and-play

4. Certification CE / UL / RoHS

IEC 61010-1

III. Main Functions

DCS card ↔ FTA signal interconnection

Transmission of analog, digital, power, and ground

Double-layer shielding, suppressing interference from frequency converters, motors, etc., reducing signal drift / jumps

Original factory standardization, no need for debugging

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

Injection-molded integrated connector: anti-loosening, anti-misinsertion, anti-vibration detachment

Suitable for all series of I/O cards

C200/C300, TPS/TDC3000

General-purpose for AI/AO, DI/DO, pulse, and communication cards

Typical application range: medium and large control cabinets: across cabinets, deep wiring, lower I/O station connection

Better suited for larger-depth and multi-level cabinet layouts compared to 1m/2m

IV. Typical Applications

Petrochemical industry: I/O cards in control cabinets → FTA (3m is the most commonly used medium to long distance)

Power industry: PKS/TPS analog/digital wiring

Papermaking / pharmaceutical / water treatment: instrument transfer in control room

Metallurgy / cement: stable transmission in high-temperature and high-dust cabinets

System expansion: adding I/O stations, cross-cabinet renovation

V. Installation Tips (Same as 001/002)

Away from frequency converters, transformers, high-power contactors (≥20cm)

Bend radius ≥ 8× outer diameter, avoid hard bending, dragging

Connector alignment and straight insertion into the slot, hearing "click" for locking

Shielding: single-ended grounding on FTA side, floating on card side (key to prevent ground current circulation)
