ABB 81EU01E-E (GJR2391500R1210 / GJR2391511R42) – INFI 90 System Module for Bailey DCS Racks
The ABB 81EU01E-E is a Bailey INFI 90 series plug-in system module, commonly used as a matched spare for installed NET 90 / INFI 90 cabinets. One thing I appreciate is its straightforward drop-in behavior—most sites can swap this card into existing module mounting units without touching the field wiring. You might notice the two ABB order codes (GJR2391500R1210 and GJR2391511R42); in many cases these denote different revisions or logistics variants of the same functional module, and we treat them as cross-compatible replacements after bench testing.
From my experience, plants standardizing on Bailey DCS keep a few of these on hand to shorten turnaround during outages. Whether you’re doing a like-for-like replacement or building a contingency stock, this module fits the typical INFI 90 backplane workflow and avoids re-engineering work.

Key Features
- INFI 90 rack compatibility – Designed for Bailey NET 90 / INFI 90 module mounting units, easing direct replacement.
- Backplane interfacing – Communicates over the INFI 90 backplane; no changes to field termination units in typical use.
- Revision alternatives – GJR2391500R1210 and GJR2391511R42 are commonly used interchangeably; we verify backplane behavior during testing.
- Service-friendly design – Front extraction handle and guided edge-connector make maintenance quicker during planned stops.
- Industrial operating range – Built for control cabinets running continuously; most sites operate these comfortably within 0–55°C.

Application Fields
The 81EU01E-E is typically selected for maintenance spares and brownfield replacements in Bailey DCS cabinets. You’ll see it in:
- Oil & gas process units (FCC, hydrotreaters, gas compression)
- Petrochemical and chemical batch/continuous plants
- Power generation balance-of-plant and boiler controls
- Pulp & paper machine sections and recovery areas
- Metals and mining utilities and process skids
A maintenance lead from a refinery told us, “We slotted the 81EU01E-E into our spare rack and it synced with our existing backplane straight away—no wiring shifts, which saved us a shift’s worth of downtime.”
Advantages & Value
- Reliability – Stable in long-run cabinet conditions; each unit is function-tested before shipment.
- Compatibility – Matches legacy Bailey INFI 90 infrastructure, avoiding requalification of field terminations.
- Cost & Lead Time – Faster availability than factory-new alternatives in many cases; predictable outage planning.
- Technical Support – Assistance with part number matching (81EU01E-E vs. GJR2391500R1210 / GJR2391511R42) and cabinet fit checks.
Installation & Maintenance
- Cabinet environment – Keep within typical 0–55°C, dry and dust-controlled. Provide ventilation as per INFI 90 cabinet design.
- ESD and handling – Use grounded wrist straps; handle by the front handle and edges. Inspect the edge connector for debris.
- Wiring – No field wiring changes expected; the module interfaces via the backplane. Verify seating and locking hardware.
- Commissioning – Power down per site procedure, insert, then power up and verify status LEDs/diagnostics on the DCS. Align revisions where your site standard requires it.
- Routine care – Periodic cabinet cleaning with dry, oil‑free air; check connector tension and record module serial/revision in the maintenance log.
Quality & Certifications
- Manufacturer quality aligned with ABB Bailey INFI 90 standards
- Typical compliance encountered in installed bases: CE; UL recognition at the system level
- 365‑day warranty from shipment date
- Test report available upon request
Note: The exact functional role of 81EU01E-E can vary by cabinet configuration. If you share your existing part label photos or DCS material list, we’ll double-check interchangeability between GJR2391500R1210 and GJR2391511R42 for your rack.
