ABB Bailey · INFI 90

IMDSO04 INFI 90 16-Channel 24 VDC Digital Slave Output Module

Sixteen 24 VDC discrete outputs for a correctly documented INFI 90 installation.

Product Summary

ABB Bailey IMDSO04 is an INFI 90 digital slave output module providing 16 discrete 24 VDC output channels in a correctly engineered control-system arrangement. It is used to command field devices through the appropriate termination and power interface and is documented for use with the FC83 configuration. The module may be sourced for planned shutdowns, repair spares or migration assessment where the original output wiring and logic must be verified. Before ordering, confirm the complete module label, field supply, output load characteristics, termination hardware, wiring polarity, controller configuration and any system-specific interlocking or diagnostic requirements.

Key Product Information

Output and Replacement Planning

• Provides 16 digital output channels for a documented 24 VDC INFI 90 arrangement.
• Confirm the FC83 and termination configuration used in the installed system.
• Verify field-load current, supply source, polarity and protection before energizing the module.
• When an IMDSO04 is considered in place of IMDSM05, output wire polarity must be reversed.
• IMDSO04 does not support DLS when considered for an IMDSM05 application; engineering review is required.
• Migration mappings do not mean that another output module is a direct replacement.

Applications

• Discrete actuator and relay command outputs in installed INFI 90 systems.
• Planned replacement of a documented 24 VDC output slave module.
• Shutdown maintenance of legacy digital-output assemblies.
• Migration surveys requiring verification of FC83, termination and field wiring.

Compatibility and Revision Notice

Confirm the exact output-circuit design before replacement. Special attention is required if the existing installation uses IMDSM05 because polarity changes and loss of DLS support may affect suitability.

• Verify the complete part number and suffix against the original nameplate.
• Confirm system generation, applicable voltage, field interface and termination arrangement.
• Confirm hardware revision and any firmware or software dependencies.
• Compare installation dimensions, target device requirements and existing wiring.
• Send clear photographs of the original equipment label and connector area.
