Description

Product Overview

The ABB IMCIS02 is a Control I/O Slave module for the Bailey INFI 90 Process Management System. Unlike a dedicated analog or digital I/O card, it combines multiple process signal types in one module, providing four analog inputs, three digital inputs, four digital outputs, and two analog outputs. The module interfaces field signals with the INFI 90 control architecture, while master modules handle the primary control functions. ABB documentation identifies the module as a single-slot assembly installed in an INFI 90 Module Mounting Unit, with field wiring routed through a termination unit or termination module.

For legacy DCS maintenance, the IMCIS02 is a practical spare where existing control stations and mixed-signal field interfaces remain in service. ABB has also identified the newer IMCIS22 as a functional replacement path for the older CIS02 in certain lifecycle applications.

Technical Specifications — IMCIS02

The signal allocation and module architecture are documented in the original ABB Bailey instruction manual.

Key Features and Benefits — IMCIS02

• Mixed analog and digital process I/O in a single INFI 90 slave module.
• Provides both input and output capability for process monitoring and control.
• Occupies one MMU slot, simplifying module-level replacement in existing racks.
• Uses termination units or termination modules for field wiring.
• Suitable for legacy DCS spare inventory and lifecycle support.
• Maximum load characteristics vary by connected circuit; ABB documentation lists 600 Ω for the IMCIS02 in a relevant I/O application.

Personally, I would verify the termination unit, field wiring, jumper settings, and installed module revision before replacement. With older INFI 90 systems, the module number alone is not enough to establish a drop-in interchange.

Installation and Maintenance — IMCIS02

Installation should follow the applicable ABB Bailey INFI 90 procedure and be carried out by qualified DCS personnel. Before replacement, isolate the relevant equipment as required and apply suitable ESD precautions. Confirm the module slot, termination unit or termination module, field cable arrangement, jumpers, and analog-output configuration. The original documentation notes that analog outputs are configured by DIP switches, while digital inputs use jumpers; analog inputs are configured at the associated termination hardware.

After installation, check the front-panel status indication, verify I/O point operation, and confirm that the connected master module sees the slave correctly. For warehouse control, retain revision information, serial data, test records, and equipment compatibility details.

Product Warranty — IMCIS02

Warranty coverage depends on the supplier and the unit’s condition. Before purchase, confirm whether the module is new, unused surplus, refurbished, or previously installed. Functional testing, visual inspection, identification labels, and agreed warranty terms should be documented before shipment.
