Technical Specifications Model: HIEE200038R0001 Measured Signal Type: AC and DC voltage, current analog feedback signals Mounting: Rack plug‑in board Power Supply: Auxiliary control power from cabinet back‑plane Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE
Functional Features Multi‑channel high‑precision sampling for power‑unit voltage and current feedback signals. Built‑in analog filter circuit suppresses high‑frequency noise mixed in measurement signals. Galvanic isolation between measurement input side and control logic side. Front‑panel LED indicators display board power‑on and fault‑alarm status. On‑board self‑diagnosis monitors signal over‑range and internal circuit hardware faults.
Application Scenarios Spare‑part replacement for HIEE200038R0001 measurement board inside generator excitation or rectifier cabinet. Analog signal sampling hardware for ABB high‑power power conversion control systems. Overhaul and spare‑part renewal projects for legacy ABB power‑control equipment.
Working Principle HIEE200038R0001 obtains auxiliary control power supply from cabinet back‑plane. Voltage and current feedback signals from power unit enter board via front‑side screw terminals. Signals pass through conditioning circuit and analog filter to eliminate high‑frequency noise. After galvanic isolation processing, high‑precision A/D conversion converts analog physical quantity into digital data. Digital measurement values are transmitted to main control processor through back‑plane connector. Self‑diagnosis circuit monitors signal over‑range and hardware anomalies and triggers fault‑alarm indication.
Installation Requirements Insert HIEE200038R0001 fully into designated cabinet slot and tighten front locking screw. Connect measurement feedback signal cables to front screw‑clamp terminals and tighten terminals to specified torque value.
