Compatible Replacement & Equivalent Models
The following modules are commonly evaluated as replacements or equivalents for the 140CRP93200. Always verify firmware, backplane, and network compatibility before substitution.
- 140CRP93100 – Single-channel S908 RIO Head; suitable when redundancy is not required
- 140CRP93200C – Conformal-coated variant for harsh environments
- 140NOE77100 / 140NOE77101 – Ethernet-based I/O head for migration to Modbus TCP architecture
- BMXCRA31200 / BMXCRA31210 – M340 RIO adapter (requires architecture redesign; not a drop-in replacement)
- Third-party S908-compatible RIO heads – Consult Konmask for validated alternatives
Note: Drop-in replacement requires identical slot position, firmware version compatibility, and S908 bus topology validation.

Replacement & Compatibility FAQ
Q: Can 140CRP93200 replace 140CRP93100 directly?
A: Yes, the 140CRP93200 is a superset of the 93100 — it adds a second channel. It is backward compatible in single-channel mode.
Q: Is 140CRP93200 compatible with all Quantum CPUs?
A: It is compatible with all Quantum CPUs that support S908 RIO. Verify your CPU’s RIO head slot count and firmware version in Unity Pro / Control Expert.
Q: Can I use this module with M340 or M580 platforms?
A: No. The 140CRP93200 is exclusive to the Quantum backplane. M340 uses BMXCRA adapters; M580 uses BMENOC Ethernet I/O heads.
Q: What cable type does S908 RIO use?
A: S908 uses RG-6 (up to 1,500 m) or RG-11 (up to 3,000 m) 75-ohm coaxial cable with BNC connectors.
Q: Does Konmask provide installation support?
A: Yes. Our technical team can assist with configuration guidance, Unity Pro setup, and compatibility verification. Contact us before purchase if needed.
