        Overview Manuals Specifications Application Performance & Efficiency Compatibility

        Features:

        • Supports 16-channel analog input modules, digital I/O, and control modules for flexible configuration
        • Features redundant Multi-Function Processors (MFPs) with 15 ms failover for high availability
        • Upgrades to Symphony Harmony, Symphony Plus, or System 800xA retain existing cabinets, cables, and control strategies
        The INFI90 INFI 90 system is built on a modular architecture that supports a wide range of I/O modules, including analog input modules with 16 channels per unit . These modules interface with field sensors and actuators, providing the foundation for process control. The I/O modules are powered by 125V DC supplies and communicate over the system's redundant data highway . This modular design allows for flexible system configuration and easy expansion, making the INFI90 INFI 90 suitable for applications ranging from small skid controls to large power plants.

        A defining characteristic of the INFI90 INFI 90 system is its redundant Multi-Function Processor (MFP) design . Two processors operate in an active/standby configuration . If the active processor fails, the standby unit takes over control in as little as 15 milliseconds, ensuring bumpless transfer without process interruption . This high availability is critical for continuous processes such as power generation, where an unplanned shutdown can have severe economic and safety consequences.

        The INFI90 INFI 90 system's long lifespan is largely due to its backward compatibility . Plants that invested in INFI90 INFI 90 in the 1990s can upgrade their control system without replacing the entire installation . ABB's "evolution without obsolescence" policy allows INFI90 INFI 90 cabinets, field wiring, and I/O modules to be reused with newer controllers (e.g., BRC 400/410) and HMIs . This approach significantly reduces upgrade costs and minimizes plant downtime.

        The INFI90 INFI 90 ABB Distributed Control System may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        General

        • Manufacturer ABB
        • Model INFI90 INFI 90
        • Condition New Original ready stock
        • Product Family CMA112 3DDE300013,DAI04
        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Power Generation: This is the most dominant sector for INFI 90. It is heavily utilized in thermal, nuclear, gas turbine, and hydroelectric power plants for comprehensive boiler control, burner management systems (BMS), turbine regulation, and Balance of Plant (BOP) sequencing.
        • Oil, Gas, and Petrochemicals: Deployed in upstream production platforms, refining blocks, and massive pipeline storage systems to manage continuous distillation columns, safety interlocks, and emergency shutdown (ESD) paths.
        • Chemical and Pharmaceutical Processing: Governs delicate multi-stage reactor controls, continuous batch processing, and ingredient blending lines where precision dosing is strict.
        • Pulp and Paper Mills: Regulates fast-moving wet-end and dry-end paper machines, chemical recovery boilers, and multi-zone lime kilns.
        • Deterministic Control Loops: Features rigid hardware separation where dedicated processing modules (such as the IMFPC or BRC series) execute complex PID loops and sequence logic independently of peripheral communications, guaranteeing sub-millisecond execution loops without CPU choking.
        • INFI-Net Communication Topology: Implements a robust, token-ring redundant network loop running over coaxial or fiber optic media. This architecture handles high-density, real-time factory data with a 0% message collision rate, preserving complete signal integrity under heavy plant alarm bursts.
        • High Industrial Immunity: The physical boards, termination units (e.g., NTDI0-A), and chassis racks are heavily isolated against harsh factory electromagnetic interference (EMI), line voltage surges, and extreme temperature variations.
        • Stepwise Migration Paths: ABB’s "Evolution without Obsolescence" strategy ensures that legacy INFI 90 hardware remains compatible with modern frameworks. For instance, a 1980s INFI 90 cabinet can be updated to ABB’s modern Symphony Plus (S+) or System 800xA architecture by replacing just the central processing card, while leaving the field wiring and termination units completely intact.
        • Cross-Generational Bus Communication: Older Network 90 (Net 90) modules communicate natively with INFI 90 cards on the same backplane or network loop, allowing factories to expand their legacy footprints incrementally without discarding earlier investments.
        • Open Protocol Connectivity: Interfaces smoothly with modern third-party subsystems (like PLCs, variable frequency drives, and smart instruments) via dedicated bridge modules supporting Modbus RTU, Modbus TCP, Profibus-DP, and OPC Server bridging.
        Description
        The INFI90 INFI 90 system was introduced by Bailey Controls in 1988 as an evolution of the Network 90 platform. It became a widely adopted DCS in power generation, water treatment, and process industries . The INFI90 INFI 90 system features a robust, fault-tolerant architecture with redundant Multi-Function Processors (MFPs) and a plant-wide data highway.

        A key advantage of the INFI90 INFI 90 system is its backward compatibility with newer generations like Symphony Harmony and Symphony Plus . This "evolution without obsolescence" policy allows plants to upgrade controllers while retaining existing INFI90 INFI 90 cabinets, cables, and I/O modules.

        The INFI90 INFI 90 system supports various I/O modules, including analog input modules (16 channels), digital input/output modules, and power supply units . It uses MODBUS (via IMPCC01) for integration with other systems . The INFI90 INFI 90 also features a redundant data highway for reliable communication between process control units (PCUs) and operator consoles.

        For modernizing legacy INFI90 INFI 90 installations, ABB offers upgrade paths to System 800xA, enabling integration with advanced HMI and asset optimization tools . The INFI90 INFI 90 system's modular architecture has allowed it to remain a reliable platform for decades.
