ABB 128057-204 & 086345-504 – Termination/Interface Assembly for INFI 90 / NET90 Control Cabinets

The part numbers 128057-204 and 086345-504 from ABB are commonly supplied as interface/termination hardware within Bailey INFI 90 / NET90 installations. From my experience, this pair is used to bridge field wiring to the system I/O or backplane using labeled terminal points and robust connectors. If you’re maintaining a legacy ABB DCS, this set typically helps reduce rewiring time during replacements and keeps your cabinet layout clean and traceable.

One thing I appreciate is the passive, straightforward design—there’s no extra power required and no new firmware to worry about. You might notice that crews value these parts because they drop into existing cabinets with minimal disruption, which is frequently the difference between a quick turnaround and a drawn-out shutdown.

Order Placement Process & Guarantees

• Lead time: in-stock items typically ship within 1 week; for backorders, no more than 1 month at the latest.
• Warranty: 365 days coverage from delivery, parts and workmanship.
• Payment: 50% advance payment; full balance required before delivery.
• Logistics: FedEx, UPS, or DHL express—tracking shared upon dispatch.
• Verification: we confirm part numbers and revision codes against your installed base before shipping to avoid mismatches.

Key Features

• Purpose-built termination – Provides a reliable interface between field wiring and ABB controller I/O in INFI 90 / NET90 cabinets.
• Passive design – No external power or firmware; reduces points of failure and simplifies replacement.
• Service-friendly labeling – Marked terminal points typically match ABB wiring diagrams, helping maintenance teams trace signals faster.
• Robust cabinet mounting – Suitable for standard control cabinet installation; supports tidy wiring and strain relief practices.
• Field-proven in brownfield upgrades – In many cases, enables module swaps without rewiring harnesses, cutting downtime.
• Consistent grounding practices – Supports standard ABB shielding/grounding methods for low-noise signal integrity.

Technical Specifications

Related & Supporting Products

• ABB INFI 90 I/O Modules (e.g., IMASI23 Analog Input, IMDSI14 Digital Input) – often wired through termination assemblies like this for clean field connections.
• ABB Controllers (e.g., BRC410) – controller-side hardware that these terminations typically serve.
• Network Interfaces (e.g., INICT03A, INNIS01) – for plant network connectivity; not directly required by the termination boards but commonly present in the same cabinet.
• Power Supplies (e.g., INPxx series) – cabinet DC power; the 128057-204 / 086345-504 themselves are passive and do not draw power.

If you’re replacing an older terminal block revision, we’ll cross-check your drawing and photos. A maintenance lead recently told us the swap on a turbine control panel took under two hours because the terminal spacing and labeling lined up with the existing harness—exactly what you want during a short outage window.

Installation & Maintenance

• Cabinet environment: Install in a clean, dry control cabinet meeting IEC/UL enclosure standards; allow space for wiring bend radius and ventilation.
• Wiring: Follow ABB terminal numbering; use ferrules on stranded conductors; torque terminals per spec; segregate analog and digital wiring to minimize noise.
• Grounding/shielding: Terminate shields at designated points only; avoid ground loops; maintain continuity to cabinet earth.
• Safety: Isolate power, verify zero energy, and tag-out before work; confirm signal isolation for live process lines.
• Routine checks: Inspect terminal tightness every shutdown cycle; check for discoloration, cracked insulation, or loosened strain relief; clean dust with dry air.
• Documentation: Update loop sheets and cabinet layout drawings after any channel move; label changes reduce troubleshooting time later.

Quality & Certifications

• CE / UL conformity typically applies at the system or assembly level for ABB cabinet components.
• RoHS status can vary by vintage; we can quote compliant stock or refurbished options depending on your site requirements.
• Warranty: 365 days from delivery. New or refurbished status, revision, and test reports are disclosed prior to shipment.
