ABB IMMFP03 Multi-Function Processor is the multi-function processor module for ABB Bailey INFI-90 and Symphony Plus distributed control systems, coordinating overall control by in terfacing with up to 64 I/O modules in any combination. The IMMFP03 family includes IMMFP03 and IMMFP03B variants; the IMMFP03B version ships with 8 MB of on-board SRAM memory, while the base IMMFP03 follows the same architecture with scalable memory options. Power is supplied at +5 V DC with a maximum draw around 10 W. Configuration and diagnostics are managed via DIP switches that set module address, bus speed, and operation mode (normal/diagnostic), with additional hardware setup and diagnostic options. The module also includes diagnostic RS-232-C ports that can be configured to operate as DCE or DTE according to jumper settings. Documentation confirms its place in the INFI-90 family and its role in coordinating logic and communications across networks of up to 64 I/O modules. Show more
