ABB 3BSE042243R1 – S800 I/O module spare for 800xA system expansion and upkeep

The ABB 3BSE042243R1 is supplied as a factory-equivalent module within the ABB S800 I/O family, used widely across 800xA and Symphony Plus installations. From my experience, part numbers in the 3BSE0422xx range are typically tied to S800 I/O hardware variants and like-for-like spares. That makes this unit a practical choice for minimizing downtime during brownfield replacements, adding I/O capacity on existing TU8xx/TU9xx bases, or holding critical shelf stock in continuous-process plants.

You might notice that S800 I/O’s compact form factor and backplane power scheme keep wiring clean and service windows short. In many cases, technicians can swap a slice in minutes, verify the channel status in 800xA, and bring the loop back online without disrupting neighboring modules.

Order Placement Process and Guarantees

• Warranty: 365 days from shipment (standard test-and-replace policy)
• Lead time: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• Native fit for ABB S800 I/O – Designed for TU8xx/TU9xx terminal bases used in 800xA/Symphony Plus systems.
• Backplane-powered – Typically receives 24 VDC via the S800 backplane; no extra field PSU in most cabinets.
• Hot-swappable practice – In many cases, modules can be replaced under power following ABB procedures to reduce downtime.
• Compact form factor – Narrow-width slice helps keep cabinet footprints small and wiring accessible.
• Industrial temperature range – Suited for typical process environments and MCC/DCS rooms.
• Lifecycle-friendly – Commonly used as a drop-in spare to keep legacy I/O islands supported without re-engineering.

Technical Specifications

Quick note from a recent retrofit: a refinery client swapped a failed S800 analog slice during a planned 30-minute window. With a like-numbered 3BSE spare, channel mapping stayed intact and loop checks were done in under 10 minutes. That’s the kind of low-friction maintenance this family is known for.

Installation & Maintenance

• Cabinet & ventilation – Mount on DIN rail with TU8xx/TU9xx bases; maintain clearance for airflow. Typical control-room conditions or conditioned panels are recommended.
• Wiring – Land field wiring on the terminal base; keep analog and digital returns separated as per ABB wiring practices. Shield and ground per channel type, especially for low-level analog.
• Power – Verify 24 VDC backplane supply and redundancy (if used) before insertion. Check load budget when adding slices.
• Hot swap – Follow ABB’s hot-insert/hot-remove procedure; confirm channel states in the 800xA faceplates after replacement.
• Routine upkeep – Inspect terminals for loosened screws, clean dust with dry air, and review diagnostics in 800xA. Firmware/parameter consistency should match controller project backups.

Quality & Certifications

• CE compliant; RoHS conformity typical for S800 I/O modules
• UL/cUL listing commonly available for S800 I/O hardware
• Manufacturer’s warranty: typically 12 months; supplied here with a 365-day coverage
• Each unit function-tested prior to dispatch; batch traceability retained

If you can share the exact installed base list or the function label on your current slice, I can confirm the precise I/O variant that maps to 3BSE042243R1 and match it one-to-one with your cabinet layout.
