Description
ABB Bailey Controls IMMPI01 infi 90
Brand Overview
-
Brand: ABB / Bailey Controls
-
About the Brand: Bailey Controls was a premier manufacturer of industrial control systems before being integrated into ABB. The combined legacy lives on through the INFI 90 and Symphony Plus platforms, which are widely recognized globally for delivering rock-solid distributed control system (DCS) architectures designed for complex, high-risk industrial processes.

Product Identification
-
Model Number: IMMPI01
-
Product Type: Multi-Function Processor Interface Module
-
Product Family: INFI 90 / Symphony Series Distributed Control System (DCS)
Technical Specifications
-
Core Functionality: Functions as a dedicated processing interface card. Its primary role is to establish a high-speed communication path between Bailey Multi-Function Processors (MFP) and external auxiliary computing hardware, offloading serial signal processing and high-volume data packet routing to optimize overall control loop speeds.
-
Core Architecture: Driven by an integrated 16-bit CMOS microprocessor designed for deterministic data execution and real-time data translation.
-
Onboard Storage: Equipped with 256 KB of battery-backed static volatile RAM (NVRAM), securing operational variables, system registers, and user configuration tables against unexpected panel blackouts.
-
Power Requirements: Runs on an internal logic supply rail of +5 VDC ($\pm$5% regulation tolerance).
-
Power Consumption: Consumes approximately 2.1 Watts (Typical current draw of 415 mA).
-
Communication Interfaces:
-
Two independent asynchronous RS-232-C serial channels for interfacing with local computers, terminals, or serial networks.
-
One high-speed parallel local bus interface (SCSI type configuration) to link with close-proximity peripheral subsystems.
-
-
Diagnostics: Features localized front-panel status LEDs indicating system power health, transmit/receive activity, and active hardware error states.
-
Form Factor & Mounting: Standard plug-in circuit card layout engineered to slide directly into an assigned slot within a Bailey Module Mounting Unit (MMU) cabinet assembly. Net weight is approximately 0.26 kg.
Target Industries
The IMMPI01 module is anchored within heavy continuous-process sectors that mandate zero system-level down-times:
-
Power Generation & Utilities: Deployed heavily in coal-fired, gas, nuclear, and hydroelectric utilities for generator, boiler, and burner management system architectures.
-
Pulp & Paper Processing: Found inside large processing mills to coordinate continuous digester towers, bleaching, and paper machine driving lines.
-
Chemical & Refining Plants: Utilized across fractional distillation, catalytic cracking, and complex batch-reactor process loops.
-
Cement & Mineral Processing: Integrated into the telemetry backbones of large-scale rotary kilns, bulk blending plants, and crushers.
Applications and Use Cases
-
DCS-to-Computer Bridging: Acts as the primary physical gateway to stream real-time operational data from INFI 90 multi-function control blocks to higher-level supervisory host computers, engineering workstations, or legacy Human Machine Interfaces (HMIs).
-
Network Bottleneck Mitigation: Manages high-density serial traffic data streams independently, preventing the master processing units from suffering communication lag during high plant activity.
-
Deterministic Synchronizing: Provides precise timing alignment across auxiliary equipment, safeguarding data packet validation with integrated hardware-based parity and checksum routines to reject corrupted signal profiles.
-
Control Infrastructure Longevity: Used by asset engineers as a direct drop-in replacement part to maintain, expand, or repair legacy Bailey Net 90 / INFI 90 cabinet rows, eliminating the need for a total control system rewrite.
