ABB S-093R (3BHB009885R5311) – Replacement Control/Power Board for PCS/ACS 6000 Converter Systems

The ABB S-093R, part code 3BHB009885R5311, is a factory-grade board used inside ABB PCS6000 and, in many cases, ACS6000 medium-voltage converter cabinets. From my experience, teams keep this module on the shelf as a fast, drop-in spare to restore availability after a fault or during preventative maintenance windows.

It’s typically associated with low-voltage control/power conditioning and signal handling within the converter’s internal rack, tying into the system backplane and supervised by the higher-level control unit. If you’re maintaining a mixed fleet of ABB MV drives, this one tends to be a straightforward swap when guided by the cabinet documentation.

• Genuine ABB spare (3BHB009885R5311) – Identified by the S-093R designation for use in ABB converter cabinets.

• Plug-in board design – Slots into the designated rack/backplane location inside PCS/ACS 6000 systems for quick field replacement.

• Backplane signal interfacing – Mixed control signals are routed through a proprietary connector; you don’t run external field wiring to the board itself.

• Works with cabinet auxiliary supply – Typically powered by the system’s 24 VDC auxiliary supply (as specified in the cabinet manual).

• Service-friendly indicators – Status LEDs and test points (where present) help speed up on-site diagnostics.

• Industrial-grade build – Robust PCB assembly suitable for enclosed cabinet environments; often conformally coated to resist dust and humidity.

• Lifecycle fit – Matched to ABB’s PCS/ACS 6000 platform so you avoid compatibility headaches and unnecessary engineering.

You might notice that this module shows up across a wide range of ABB medium-voltage installations. Typical usage includes:

• Wind and renewable power converters (PCS6000 platform)

• Medium-voltage drives for pumps, fans, compressors and conveyors (ACS6000)

• Marine propulsion and offshore auxiliary drives in controlled cabinet environments

• Metals, mining, cement and oil & gas facilities where high uptime is critical

Feedback from a wind farm O&M lead: “Swap took less than 20 minutes with the cabinet offline; once reseated and powered, the converter synced without extra tuning.”

• Compatibility confidence – Matched to ABB’s PCS/ACS 6000 design rules, reducing commissioning friction.

• Lower downtime risk – Field-replaceable form factor and familiar connectors speed up restoration.

• Predictable total cost – Keeps your installed base standard; no ad?hoc redesigns or control logic edits in most cases.

• Spares strategy – Easy to stock as a risk-mitigation spare for critical lines or remote assets.

• Supportable – Documentation, parameter maps and test procedures are available within the ABB system manuals.

• Safety first – De-energize and lock out the cabinet. Wait for DC link to discharge per the manual. Use ESD protection when handling boards.

• Environment – Install within the converter cabinet; maintain clearance and ventilation. Avoid condensation and airborne conductive dust.

• Wiring/Seating – Inspect connectors and the backplane edge for wear. Insert evenly until fully latched; never force the board.

• Verification – After power-up, check status LEDs/diagnostics. Confirm the higher-level control recognizes the module.

• Upkeep – Quarterly visual inspection for hot spots, discoloration, or loose hardware. Light, dry air cleaning as needed; no solvents.

• Firmware/Parameters – If the system architecture uses parameterized boards, back up settings beforehand and restore as instructed by the manual.

• Battery/UPS note – Where cabinets include buffer batteries or UPS, periodic capacity checks are advisable (typically annually) per site procedures.

• Manufacturing quality – Produced under ABB quality systems (ISO 9001). Traceability by part and revision code.

• Conformity – When installed as part of the original ABB converter, the complete system conforms to applicable CE/UL directives for that platform.

• Materials compliance – RoHS alignment generally applies to control electronics; exemptions may apply for MV systems and service spares.

• Warranty – Standard 12?month warranty from date of shipment on the module, assuming proper installation and operating conditions.

In many cases, this board operates alongside the cabinet’s auxiliary 24 VDC power supply, the main control unit, and I/O modules on the internal backplane. If you’re refreshing spares, teams typically pair it with:

• Cabinet auxiliary PSU (24 VDC) used by control electronics

• Backplane motherboards or rack hardware for the PCS/ACS 6000 slot

• Control unit and interface cards that manage fieldbus (e.g., PROFIBUS/Modbus via the main controller)

If you need us to double-check fit by converter type, serial, or software level, share a cabinet nameplate photo or the system BOM. One thing I appreciate with ABB MV platforms is the strong revision control—matching the 3BHB009885R5311 code to your cabinet documentation usually gets you the right part the first time.
