Compatible Replacement & Equivalent Models
When the 900C75S-0560 is unavailable or end-of-life, the following models may serve as functional replacements or upgrades depending on your system configuration. Always verify firmware compatibility and rack slot requirements before substitution.
- 900C75-0560 — Non-redundant C75 CPU; same processing core, no hot-standby support. Suitable for non-critical loops.
- 900C75R-0560 — Alternate redundant variant; verify suffix compatibility with your HC900 firmware revision.
- 900C30S-0560 — C30 Redundant CPU; lower I/O capacity, suitable for smaller process cells.
- 900C50S-0560 — C50 Redundant CPU; mid-range capacity, direct upgrade path from C30.
- Honeywell 900C75-0001 — Earlier C75 revision; confirm firmware and rack compatibility.
- Third-party compatible CPUs — Contact Konmask for vetted cross-reference options for legacy HC900 racks.

Selection Guide
Use the table below to select the correct HC900 CPU for your application:
- Small systems (<300 I/O, non-critical): 900C30-0560 (C30, non-redundant)
- Small systems (<300 I/O, redundant): 900C30S-0560 (C30 redundant)
- Mid-range systems (300–1000 I/O, non-critical): 900C50-0560 (C50, non-redundant)
- Mid-range systems (300–1000 I/O, redundant): 900C50S-0560 (C50 redundant)
- Large systems (>1000 I/O, non-critical): 900C75-0560 (C75, non-redundant)
- Large systems (>1000 I/O, redundant) ← THIS MODEL: 900C75S-0560 (C75 redundant) ✓
Suffix “S” denotes redundancy support. Always match CPU suffix to your rack and firmware revision.

Replacement & Compatibility FAQ
Q: Can I replace a 900C75-0560 (non-redundant) with a 900C75S-0560 (redundant)?
A: Yes, the redundant CPU is backward compatible in a non-redundant configuration. You gain the option to add a second CPU for redundancy later without hardware changes.
Q: Is the 900C75S-0560 compatible with older HC900 racks?
A: Generally yes, but verify the rack backplane revision. Some very early HC900 racks may require a backplane firmware update. Contact Konmask for compatibility confirmation.
Q: What cable is required for the redundancy link?
A: A standard Cat5e or Cat6 Ethernet crossover or straight-through cable (depending on firmware version) connects the two CPUs via their dedicated redundancy Ethernet port.
Q: Can I use a 900C50S-0560 as a drop-in replacement for the 900C75S-0560?
A: No — the C50 has lower processing capacity and fewer supported I/O points. It is a downgrade and may not support your existing program without modification.
Q: Do you provide a certificate of conformance?
A: Yes. Request it at the time of order via email.
