Description

Hardware and Performance Specifications Auxiliary supply: 24 V DC, 18‑30 V DC wide‑range input Power consumption: ≤6 W Analog Inputs: Multi‑channel configurable (0‑10 V / 4‑20 mA) Analog Outputs: Configurable analog output channels Binary I/O: Galvanic‑isolated digital inputs, relay outputs Signal accuracy: ±0.1 % full‑scale Isolation: Reinforced galvanic isolation between field side and drive internal circuit Communication interfaces: Drive internal back‑plane bus Mounting mode: Plug‑in PCB board for ACS600 / ACS800 drive rack, installation position POS.A6091 Protection class: IP20 Operating temperature: ‑25 ℃ ~ +70 ℃ Storage temperature: ‑40 ℃ ~ +85 ℃ Humidity: 5‑95 %RH non‑condensing EMC compliance: Comply with IEC 61000‑4 series industrial EMC standards Dimension & weight: 210 × 135 × 35 mm, weight approx. 0.35 kg Certifications: CE approval

Main Functions Condition and filter drive internal measuring signals and external process analog signals. Complete high‑precision A/D conversion for multi‑channel analog inputs, upload measuring data to drive main controller through internal back‑plane bus. Generate analog output reference signals for external meters and peripheral control equipment. Acquire binary status signals from field‑site devices. Front‑panel LED indicators display power‑on status, running status and fault alarm codes for on‑site inspection. Hardware self‑diagnosis detects channel failure, signal over‑range and internal circuit faults, upload fault codes to drive main unit. Parameter configuration and channel calibration are completed by ABB drive commissioning tool.

Installation Requirement Plug‑in installation at position POS.A6091 inside ACS600 / ACS800 drive rack. Separate high‑power power cables and weak‑signal measuring cables. Ensure reliable cabinet protective grounding. Auxiliary 24 V DC power supply shall stay within rated operating range. After board replacement, confirm full part‑number 3AFE61320946P0001 matches original drive configuration, download complete drive parameter set. Perform analog‑channel calibration, binary‑I/O point‑to‑point test and internal bus communication verification. This interface board is drive‑model specific; different hardware revisions cannot be directly interchanged without parameter adaptation. Do not put into service until no hardware self‑diagnosis fault alarm exists.

Typical Application Scenarios Measurement‑interface spare‑part for ABB ACS600 / ACS800 large‑capacity AC variable‑frequency drives, applied for metallurgy, mining and power‑plant auxiliary‑motor drive‑system maintenance and retrofit.

Key Features

1. Dedicated LD MUI‑01 measurement‑interface board for ACS600/ACS800 drives, integrates multi‑channel analog and binary I/O functions.
2. High‑precision signal acquisition with reinforced galvanic isolation, good anti‑interference performance for heavy‑industrial sites.
3. Plug‑in rack‑mount structure, installed at cabinet position POS.A6091, convenient for on‑site replacement and maintenance.
4. Comprehensive self‑diagnosis function for fast fault location.
5. Strict full‑part‑number matching shall be observed during spare‑part replacement; POS.A6091 is only drawing position marker, not part number.
