Bailey IMMFP02 Infi 90 Multi-Function Processor Module

Bailey INFI 90 Multi-Function Processor Module, IMMFP02, is the brain of the INFI 90 control system. This standalone MFP module provides a multi‑loop analog, sequential, batch and advanced controller that handles data acquisition and information processing while communicating with up to 64 I/O modules in any combination. It operates in three modes—execute, configure, and error—where execute runs user‑defined control algorithms while continuously self‑checking for faults, and configure lets engineers edit or add algorithms; if a fault occurs in execute, the module automatically enters error mode to support safe recovery. The IMMFP02 supports redundancy through a 1 Mbaud CPU‑to‑CPU link, enabling a hot‑standby backup MFP to take over without interrupting the process. Alternate part numbers include YIMMFP02, RIMMFP02, PIMMFP02, and IMMFP02R, reflecting its long‑standing use in INFI 90 installations. Distributor data commonly lists a 32‑bit processor core with 512 KB ROM and a typical power profile of +5 VDC with modest current draw, designed to pair with ABB’s INFI 90 I/O modules in demanding industrial environments.
