Description
Product Introduction
ABB HC800 (HPC800) is the central control processor in ABB’s Symphony Plus S+SD DCS, designed for high-speed loop execution and complex logic in continuous process industries such as power, oil and gas, and chemicals.colletplc+1
This module delivers up to 3× the application performance of earlier SD controllers, supports hot-swapping for minimal downtime, and maintains backward compatibility with existing HN800 I/O and legacy S+SD configurations when firmware levels are matched.colletplc+1
Frequently Asked Questions
Q: Does the HC800 support hot-swapping?
A: Yes. The HC800 is designed for hot-swap replacement on the MB810 base, allowing you to pull and insert the controller without shutting down the plant network—provided redundant power and communication paths are intact
Q: Is the HC800 obsolete? Are there direct replacements?
A: The HC800 is effectively obsolete in ABB’s current catalog, but it remains the direct controller for S+SD systems. Replacement units are sourced as New Surplus. For new builds, ABB typically migrates to newer Symphony platforms, but HC800 still serves as a like-for-like swap in existing S+SD racks.library.e.abb+1
Q: Will I lose my program when replacing the HC800?
A: No, if you follow procedure. The control strategy resides in engineering station backups and is downloaded to the controller. Before swapping, record the exact firmware version and virtual/physical dipswitch settings (SW1–SW5), then restore the same configuration on the replacement unit to avoid communication mismatches.
Q: Are these units factory-new or refurbished?
A: We supply HC800 modules as New Surplus (original packaging, never installed) or verified stock with full inbound traceability. They are not ABB-certified remanufactured units unless explicitly stated. Always request packing lists and serial trace for audit.new.abb+1
Q: What warranty and lead time should I expect?
A: Standard surplus suppliers offer 12 months warranty against defects; ABB’s own factory warranty on new units is 24 months, but that rarely applies to HC800 today. Lead times vary: “in stock” units ship in 1–3 days, but customs and export paperwork can add 5–8 working days depending on origin.
