ABB LTC391AE01 HIEE401782R0001 / HIEE410507P201 Interface Board

The ABB LTC391AE01 (HIEE401782R0001, HIEE410507P201) is a high‑precision interface monitoring board for ABB industrial drive and power control systems. It collects multi‑channel electrical measurement signals, executes data processing and communicates with main controller via RS‑485 bus, realizing real‑time condition monitoring for power conversion equipment.

This plug‑in PCB board is coated with conformal coating for anti‑dust and anti‑interference capability. It integrates over‑range detection and hardware fault diagnosis functions, and can report abnormal working parameters to upper‑level control system. It is designed for long‑term stable operation inside power plant and heavy‑industry drive cabinets.
