ABB INTKM01 – INFI 90 termination/interface module for reliable DCS cabinet wiring

The ABB INTKM01 is part of the ABB Bailey INFI 90 family, typically used as a termination/interface module that bridges field wiring to the control system backplane. From my experience, plants keep INTKM01 units as strategic spares when they’re consolidating older cabinets or adding marshalling points without reworking the whole I/O stack. It seems to be a straightforward, low‑risk way to maintain wiring integrity, especially during phased upgrades or when you just need a drop‑in replacement for a legacy slot.

Key Features

• Purpose-built termination for INFI 90 – Routes field signals cleanly to the system bus/backplane, reducing wiring errors.
• Drop-in replacement behavior – In most cases, no software changes; swap the module, verify wiring, and you’re back online fast.
• Passive or minimal power draw – Typically does not require external power; when applicable, it draws low voltage from the backplane.
• Cabinet-friendly form factor – Fits standard ABB Bailey racks and marshalling arrangements commonly used in legacy DCS cabinets.
• Stable in brownfield upgrades – Useful when modernizing one section at a time, keeping field terminations intact.
• Serviceable connections – Hardware-level terminations you can visually inspect and torque, which maintenance teams usually prefer for fault tracing.

Related or Supporting Products

• ABB INBTM01 – Basic termination module often used for general field wiring; a practical alternative in simpler marshalling layouts.
• ABB INNIS01 – INFI-NET network interface module; pairs with termination modules when adding or re-segmenting INFI-NET.
• ABB INICT01 – Interface/communication module within the INFI 90 family; useful when extending network connectivity.
• ABB IMASI23 / IMDSI14 – Representative analog/digital I/O modules commonly wired through termination hardware in Bailey systems.

One thing I appreciate is how these parts mix-and-match in brownfield plants. A maintenance lead at a power station told us they swapped an INTKM01 during a night shift and kept the loop checks for morning—no surprises on startup, which is usually the goal.

Installation & Maintenance

• Cabinet & rack – Install in ABB-approved INFI 90 racks or termination panels; ensure adequate ventilation and maintain free airflow around modules.
• Wiring – Use labeled, shielded cable where specified; keep field wiring segregated from power cables to minimize noise.
• Grounding – Bond shields at the cabinet end per site grounding policy; avoid ground loops by following single-point grounding practices.
• Safety – De-energize the rack segment if required; follow lockout/tagout. Verify slot and connector orientation before insertion.
• Routine checks – Periodically re-torque terminal screws, inspect for oxidation, and verify continuity on critical loops after outages.
• Documentation – Note any module replacements with serial/slot info; this typically speeds up future troubleshooting and audits.

Quality & Certifications

• Manufactured to ABB quality standards; facilities are commonly ISO 9001 certified
• CE compliance where applicable for control cabinet use
• RoHS status depends on production vintage; many legacy modules pre-date RoHS—spares are supplied for maintenance of existing equipment
• Warranty: 12 months from delivery
