Technical Specifications Cable Structure: Multi‑pair individually shielded twisted‑pair analog signal cable Connector Type: D‑Sub high‑density industrial connector Conductor Gauge: 22 AWG Shielding: Individual pair shielding plus overall copper braid shielding Rated Operating Voltage: 300 V Operating Temperature: ‑40 °C to +85 °C Storage Temperature: ‑50 °C to +90 °C Certifications: CE, UL Cable Length: Fixed specified cabinet‑use length
Functional Features Dedicated matching for Tricon analog input and analog output I/O modules. Double‑layer shielding structure suppresses crosstalk and external electromagnetic interference. Gold‑plated connector contacts realize low‑contact‑resistance stable analog signal transmission. Factory pre‑terminated assembly eliminates on‑site crimping and wiring errors. Resist cabinet‑internal vibration and mechanical stress. Support quick disconnection for module maintenance and replacement work.
Application Scenarios Analog signal interconnection between Tricon analog I/O modules and termination panels. Petrochemical SIS system 4‑20 mA analog signal cabinet‑internal transmission. Oil‑gas processing plant safety instrument system analog loop wiring. Chemical‑plant reactor safety‑related analog signal interconnection. Power‑plant safety‑monitoring analog signal cabinet internal connection.
Performance Parameters Signal Transmission Performance: Low signal attenuation for analog 4‑20 mA loop signals Anti‑crosstalk Performance: Individual pair shielding reduces inter‑pair signal crosstalk Contact Reliability: Gold‑plated contacts maintain stable performance after multiple plug‑unplug cycles Mechanical Durability: Adapt long‑term continuous operation inside industrial control cabinet
Material Composition Conductor: Tinned multi‑strand copper conductors. Insulation: High‑temperature flame‑retardant polymer insulation for each twisted‑pair. Shielding: Individual pair foil shielding and overall copper braid shielding. Outer Jacket: Flame‑retardant industrial‑grade outer protective sheath. Connector Parts: Flame‑retardant engineering‑plastic shell, gold‑plated metal contact pins.
Structural Characteristics Pre‑fabricated complete assembly with connectors assembled at both cable ends. One‑end D‑Sub high‑density connector for direct mating with analog I/O module. Other‑end dedicated connector for mating with corresponding analog termination panel. Dual‑layer shielding runs through full cable length. Flexible cable body meets cabinet‑internal bending‑radius requirement.
Working Principle Analog signals from Tricon analog I/O module enter assembly cable via D‑Sub connector. Each signal twisted‑pair uses independent foil shielding to restrain inter‑pair crosstalk. Overall copper braid shielding isolates external industrial electromagnetic noise. Signals transmit to external termination panel through opposite‑end connector. Shield layers connect to cabinet protective grounding point following official specification to divert interference energy.
Installation Requirements Arrange cable routing inside control cabinet and keep required minimum bending radius, avoid sharp‑angle bending. Fully insert and lock module‑end D‑Sub connector onto corresponding analog I/O module port. Fasten opposite‑end connector locking screws onto matched analog termination panel. Complete shielding‑layer grounding strictly comply with Tricon official grounding instruction. Separate analog assembly cables from high‑voltage power cables and digital signal cables. Avoid close layout with frequency converter and other strong‑interference equipment.
