Compatible Replacement & Equivalent Models
The following models are commonly evaluated as functional replacements or equivalents for the MU-TDOR22. Always verify electrical and firmware compatibility before substitution:
- Honeywell 51304427-150 — Revised revision of the same TDOR22 series; direct drop-in candidate
- Honeywell MU-TDOR12 (51304426-100) — 16-channel DO variant; suitable when lower channel density is acceptable
- Honeywell 51309276-175 — Digital Output module for Experion HS; verify backplane compatibility
- Honeywell CC-TDOB01 (51308385-175) — C300 series DO module; requires C300 controller infrastructure
- Third-party compatible: Consult Konmask engineering team for validated cross-reference options
Note: Replacement modules must match output type, channel count, voltage rating, and firmware revision. Contact us for a compatibility assessment.

Replacement & Compatibility FAQ
Q: Can the MU-TDOR22 replace the MU-TDOR12?
A: Not directly — the TDOR12 is a 16-channel module while the TDOR22 is 32-channel. Physical slot and wiring termination differences must be evaluated.
Q: Is a refurbished 51304427-100 reliable for production use?
A: Yes, when sourced from a reputable supplier with documented testing. Konmask provides functional test reports on all refurbished units.
Q: What is the lead time for new stock?
A: Typically 3–10 business days for in-stock units; 4–8 weeks for factory-new orders. Contact us for current availability.
Q: Do you provide a certificate of conformance?
A: Yes. CoC and test documentation are available upon request for all orders.
Q: Can this module be used in SIL-rated safety systems?
A: The MU-TDOR22 is not rated for SIL applications. For safety-critical loops, use Honeywell Safety Manager I/O modules.
