ABB MPRC‑086444‑003 Product Description

The MPRC‑086444‑003 is an ABB MPRC‑series rack‑mount measurement‑processing fiber‑optic interface board, belonging to legacy ABB industrial drive and power‑system control hardware platform. This module implements high‑speed optical‑fiber data transmission, high‑precision signal sampling and local measurement‑data pre‑processing. It converts electrical signals into optical signals for long‑distance anti‑interference communication between main control unit and field power‑conversion hardware, effectively isolating electromagnetic interference in high‑power cabinets. It is mainly used as spare‑part for aging ABB large‑drive systems; the suffix‑003 represents hardware revision variant within the 086444 product family, alongside 001, 005 other revisions.

Product Features

• Dedicated fiber‑optic communication & measurement‑processing board, realizes galvanic isolation between control side and high‑power power‑stage
• High‑speed optical‑fiber link, resists strong electromagnetic interference inside high‑power converter cabinets
• On‑board signal pre‑processing circuit for fast sampling of current, voltage and status feedback signals
• Standard rack‑mount card‑format structure, installs inside ABB control cabinet chassis, hot‑swap mechanical‑support design
• Rich self‑diagnostic functions, monitors optical‑link health, signal anomaly and module status, reports fault codes to main controller
• 24 VDC auxiliary power supply, operating temperature range‑20 °C ~ +55 °C, IP20 protection for cabinet‑only installation
• Revision‑003 variant of 086444 hardware family; pin‑compatible replacement reference:‑001,‑005 need firmware and system configuration verification before substitution
• Original production discontinued; mainly serves as after‑sales spare‑part for existing field equipment.

Application Scenarios
