Why Engineers Specify This Model
- HART Pass-Through: Enables asset management and diagnostics via ABB Asset Vision or third-party HART tools without additional hardware.
- Hot-Swap Capability: Modules can be replaced under power without shutting down the controller or adjacent channels — critical for continuous process plants.
- Redundancy Support: Compatible with redundant S800 I/O bus configurations for SIL-rated safety loops.
- Compact Footprint: 8 channels in a single slim module reduces cabinet space and wiring costs versus discrete I/O solutions.
- Proven Platform: S800 I/O has over 20 years of installed base in global process industries, ensuring long-term spare parts availability.
- Seamless AC 800M Integration: Native Modulebus communication eliminates gateway hardware and simplifies engineering in ABB 800xA / Symphony Plus environments.

Application-Specific FAQ
Q: Is the IMFAI01 compatible with the AC 800M PM864A controller?
A: Yes. The IMFAI01 is fully compatible with all AC 800M controller variants including PM851, PM856, PM860, PM861, PM864, PM864A, PM866, and PM866A via the S800 I/O Modulebus.
Q: Can I use IMFAI01 in a SIL 2 safety loop?
A: The S800 I/O platform supports SIL 2 configurations when used with appropriate redundancy and certified safety logic in ABB 800xA. Consult your functional safety engineer and the ABB SIL certificate documentation for your specific loop design.
Q: Does IMFAI01 support HART pass-through to the DCS?
A: Yes. HART communication is passed through to the AC 800M controller, enabling device diagnostics and parameterization via ABB Asset Vision or compatible HART masters.
Q: What MTU (termination unit) do I need?
A: The IMFAI01 requires a compatible S800 MTU. Common options are TU810V1 (non-isolated) and TU812V1 (isolated). Selection depends on your field wiring and isolation requirements.
Q: Can I hot-swap the IMFAI01 without process interruption?
A: Yes, the S800 I/O system supports hot-swap replacement. The controller will detect the new module and resume I/O scanning automatically, minimizing process downtime.
Q: Do you supply the MTU and bus coupler as well?
A: Yes. Contact us with your full requirements and we will provide a consolidated quote for all S800 I/O components.
