Technical Specifications Part Type: Dedicated FBM‑to‑Termination‑Assembly Shielded Cable Assembly Application: Signal inter‑connection between FBM module and termination‑assembly board Cable Structure: Multi‑pair twisted‑pair shielded signal‑cable with factory‑assembled connectors Operating Temperature: 0 °C to +60 °C Storage Temperature: −40 °C to +85 °C Relative Humidity: 5%‑95%, non‑condensing Certifications: Complies with Foxboro original‑equipment spare‑part specification
Functional Features Factory‑finished cable assembly with matched connectors for fast on‑site installation. Twisted‑pair overall‑shielded cable‑design reduces electromagnetic‑noise coupling. Strictly follows Foxboro hardware pin‑definition standard to avoid wiring‑pin‑mismatch risk. Guarantees signal‑transmission quality for analog and discrete control‑signal loops inside control cabinet.
Application Scenarios Widely used inside Foxboro DCS control cabinets of petrochemical, chemical and power‑plant industries. Serves as dedicated inter‑connecting cable between FBM I/O modules and corresponding termination‑assembly hardware.
Performance Parameters Cable shielding and transmission‑performance satisfy I/A series analog‑signal and discrete‑signal transmission‑specification. Factory‑crimped connectors maintain stable contact performance under cabinet‑vibration environment.
Structural Characteristics Multi‑core twisted‑pair overall‑shielded signal‑cable body. Both cable ends are equipped with factory‑installed matched connectors following Foxboro pin‑assignment standard. Outer‑surface marks part‑number P0400HH for spare‑part identification.
Working Principle P0400HH cable assembly establishes signal‑transmission path between FBM module bottom connector and termination‑assembly‑board connector. Analog‑signal or discrete‑signal from FBM module is transmitted through cable internal conductors to termination‑board, and further routed to field‑instrument‑wiring terminals. Overall shielding layer suppresses external electromagnetic‑interference from coupling into internal signal‑conductors.
Installation Requirements Confirm P0400HH cable matches target‑FBM‑module and termination‑board‑hardware before installation. Insert two‑end connectors firmly into FBM‑module connector and termination‑board‑connector respectively. Arrange cable routing inside cabinet, keep distance from high‑voltage‑power‑cables. Complete shielding‑layer grounding according to official grounding‑technical‑specification.
Usage Notes Do not cut or modify factory‑assembled cable‑end connectors arbitrarily. Prevent sharp‑hardware from scratching cable outer‑shield layer during cabinet‑wiring‑construction. Check connector plug‑in tightness periodically for long‑term‑running control‑system cabinets.
