Description
Product Description
The IMMFP03R is a high-performance control processor designed for ABB Bailey INFI 90 and Net 90 distributed control architectures. It functions as the central execution unit responsible for real-time control processing, system coordination, and communication management across I/O subsystems.
Engineered with redundancy capability, this module supports hot-standby configuration, allowing continuous operation in mission-critical environments such as power generation units, refining facilities, and large-scale process plants.
