Description

The HIEE300900R1 PP‑C322‑BE (PPC322BE) is a combined CPU + fieldbus master Eurocard for ABB AC 800PEC, widely used in UNITROL excitation systems, LCI large synchronous drives, rolling mill converters and power electronic closed‑loop control. It integrates the PSR‑2 real‑time processor and PROFIBUS DP master, handles high‑speed control algorithm execution and deterministic fieldbus communication with remote I/O, drives and instruments.
