Product Introduction
Redundant control loops cannot afford ambiguous spare parts. The ABB SA168 3BSE003389R1 is a redundancy adapter used in AC 800M controller systems, intended to support synchronized operation between redundant CPUs. It is typically deployed where continuous process availability matters—turbines, boilers, critical pumps, and safety-linked sequences.
This module helps reduce risk during a CPU fault by maintaining the communication path required for redundancy handover. Keeping a verified 3BSE003389R1 unit in stock avoids waiting on long OEM lead times and limits plant exposure during unplanned controller maintenance.

Key Selling Points & Differentiators
- OEM-identifiable part number for clean procurement approval.
- Direct replacement for AC 800M redundant controller positions.
- Factory-sealed surplus reduces commissioning uncertainty.
- ESD-safe packaging protects sensitive controller interfaces.
- Suitable for plants standardizing spares across redundant AC 800M racks.
- Not recommended for non-redundant AC 800M CPUs, S800 I/O, or non-ABB controllers.
Quality Transparency SOP
- Visual inspection: Check housing, connectors, labels, and part number 3BSE003389R1.
- ESD handling: Anti-static bag, grounded work surface, sealed until installation.
- Connector verification: Confirm pin integrity and mechanical alignment before rack insertion.
- Continuity check: Perform basic continuity checks on external interfaces where applicable.
- Documentation review: Match part number, revision, lot/serial traceability, and packing condition.
Technical Risk Avoidance
- ❗ Confirm your AC 800M system is configured for redundancy before installing this module.
- ❗ Verify firmware and hardware compatibility with your existing redundant CPU pair.
- ❗ Follow proper controller shutdown and rack safety procedures before replacement.
- ❗ Do not force connectors or mounting hardware. Misalignment may indicate wrong slot, wrong revision, or backplane damage.
Buyer’s FAQ
- Is this a genuine ABB part?
Yes. It is supplied as ABB SA168 with part number 3BSE003389R1. Traceability is verified through labeling and packaging. - Is it new or refurbished?
Listed as New Original / New Surplus, factory sealed. It is not a repaired or refurbished module. - Will it fit my AC 800M controller?
It is designed for AC 800M redundant controller systems. Confirm your CPU type, redundancy option, and rack configuration before ordering. - Can it be used in a non-redundant CPU rack?
No. It is intended for redundant CPU applications. Using it in an unsupported configuration may cause faults or unused hardware. - What warranty and lead time apply?
Standard 12-month warranty from shipment. In-stock units can ship quickly; exact lead time depends on current inventory.
