ABB Bailey IMCIS22 INFI 90 Control I/O Slave Module

The ABB Bailey IMCIS22, also cataloged as the IMCIS22 Control I/O Slave Module, provides field signal interfacing within ABB Bailey INFI 90 and Net 90 distributed control systems. It supports control I/O functions for process signal acquisition and output handling, with system power supplied through the backplane. Signal compatibility and channel configuration must be verified against the installed system documentation.

Hardware Specifications

Backplane Interface and Signal Compatibility

The IMCIS22 operates as a Control I/O Slave Module in the ABB Bailey INFI 90 and Net 90 architecture. Its field signal handling depends on the installed I/O configuration and associated system hardware.

The reported 24 VDC supply is derived from the system backplane. This value describes the stated supply arrangement, not the module's confirmed current consumption or total power dissipation.

Digital and analog signal types must be checked against the applicable module documentation, termination hardware, and system configuration. The listed signal levels should not be interpreted as universal input ratings for every channel.

Frequently Asked Questions

Q: Can the IMCIS22 be connected directly to 24 VDC, 48 VDC, 125 VDC, and 120 VAC field signals?

A: These levels are listed as examples of supported industrial signal types, but the allowable voltage depends on the specific channel and module configuration. Confirm the applicable electrical ratings and termination arrangement before wiring field signals.

Q: Does the IMCIS22 require an independent 24 VDC power connection?

A: The supplied information identifies 24 VDC power derived from the system backplane. An independent power connection should not be assumed. Verify the installed rack and backplane requirements before installation.

Q: Are SPCIS22, PIMCIS22, and YIMCIS22 direct replacements for the IMCIS22?

A: These part numbers are listed as alternatives or successors, but direct interchangeability is not established by the supplied data. Verify hardware revision, system compatibility, signal configuration, and installation requirements before substitution.

Field Installation Guidelines

1. Confirm the module identification and compatibility with the installed ABB Bailey INFI 90 or Net 90 system.
2. Inspect the rack, backplane connector, and module contacts for physical damage before installation.
3. Isolate the relevant equipment and follow site electrical safety procedures before inserting or removing the module.
4. Verify field signal voltage, signal type, polarity, and termination assignments against the applicable hardware documentation.
5. Route analog signal wiring separately from high-current and switching conductors where practical to reduce electrical interference.
6. Apply shield grounding according to the system wiring specification and site grounding scheme. Avoid introducing unintended ground loops.
7. Confirm backplane power availability and system configuration before commissioning.
8. Check channel status, controller diagnostics, and field signal response after installation. Do not assume hot-swap capability without explicit confirmation in the manufacturer's documentation.
