ABB IMFEC11 – Communication Interface Module for Symphony/INFI 90 DCS Expansion
The ABB IMFEC11 is a communication interface module used in Symphony / INFI 90-based control systems to expand network connectivity and coordinate traffic between controllers and remote I/O. From my experience, teams adopt the IMFEC11 when they need stable, rack-based communications without adding extra conversion hardware. You might notice that many sites deploy it as part of a redundant pair to keep the process online during maintenance.

Key Features
- Symphony/INFI 90 rack integration – Plugs directly into the standard ABB rack, using the backplane for power and system communications.
- Communication expansion – Typically used to extend control network connectivity to remote I/O or segment traffic for larger nodes.
- Redundancy-ready design – In many cases deployed in redundant pairs to achieve high availability during switchover or maintenance.
- Diagnostics and status – Front-panel indicators make it easy to verify module health and communication status at a glance.
- No direct field I/O – Functions as a network/system interface module, keeping process signals on dedicated I/O cards.
- Service-friendly – Module-level replacement is straightforward; with redundancy in place, many sites perform online swaps.

A customer note we hear often: “Once we introduced a redundant pair of IMFEC11 modules, scheduled maintenance became much simpler—we could keep the process up while swapping a single card.” That seems to be the typical experience in larger continuous processes.
Installation & Maintenance
- Cabinet and rack – Install in a compliant Symphony/INFI 90 rack within an enclosed cabinet. Allow space for airflow; avoid heat sources.
- Wiring and grounding – Maintain proper rack grounding and shield terminations. Keep communication cabling separated from high-voltage runs.
- Redundancy – If using paired IMFEC11 modules, verify matching firmware and configuration before switchover tests.
- ESD handling – Handle modules with ESD protection. De-energize the slot unless your redundant architecture explicitly supports online replacement.
- Routine care – Inspect connectors and edge contacts yearly; clean dust with dry air; back up configuration; apply firmware updates approved for your DCS revision.
- Environment – Typical operation 0–60 °C and 5–95% RH non-condensing. Keep the cabinet closed to prevent contaminants from reaching the card.
