ABB PPC902AE101 (3BHE010751R0101) – Processor Board for High‑Reliability Control Systems

• OEM ABB module (3BHE010751R0101): Genuine processor board for the PPC900 series, ensuring firmware and hardware alignment.

• Backplane-powered: Draws DC power from the system rack; no external PSU cabling, which typically speeds up swap‑outs.

• Drop‑in replacement: Designed for fast changeover in maintenance windows—helps minimize stop time in critical lines.

• System bus integration: Communicates via the ABB backplane; I/O is handled by dedicated modules, so no field rewiring needed.

• Service-friendly design: Front-edge access for service/diagnostics on most installations, depending on the rack and revision.

• Stable lifecycle support: Widely deployed in ABB DCS and drive control cabinets, so spares logistics are usually straightforward.

In many cases this board sits at the heart of ABB DCS nodes or drive control cabinets. Commonly seen in:

• Metals & rolling mills – coordinated drives and line control

• Pulp & paper – machine direction control and web handling

• Oil & gas – compressor/utility systems and package skids

• Power generation & utilities – balance-of-plant subsystems

• Chemicals & pharmaceuticals – continuous process control

• Reliability: Stabilized hardware platform that field techs trust—spare-on-shelf strategy usually pays off during unplanned stops.

• Compatibility: Works within the PPC900 ecosystem, helping retain existing logic, I/O structure, and cabinet wiring.

• Cost & downtime: Drop‑in replacement approach can cut changeover time, which in many plants is more valuable than the part cost itself.

• Supportability: Clear traceability via 3BHE010751R0101; makes firmware and revision alignment simpler for maintenance teams.

• Cabinet environment: Use a clean, ventilated, and grounded cabinet; comply with ABB’s rack and clearance rules.

• ESD safety: Handle the board with ESD protection; isolate power and discharge the cabinet before removal/insert.

• Wiring & seating: No field wiring to the CPU; ensure the board is fully seated in the backplane and retaining screws are secured.

• Firmware alignment: Match firmware/loader revisions to the running system; back up application/programs prior to changeover.

• Routine care: Periodic dust cleaning with dry air; check connector condition; review event logs; consider scheduled firmware updates after validation.

• CE compliance for industrial control environments

• RoHS conformity by production batch (where applicable)

• Manufactured under ISO 9001 quality systems (ABB)

• Warranty: 12 months from delivery (365 days)
