Replacement & Compatibility FAQ
Q: Can the 51202306-010 be used as a direct drop-in replacement for 51202306-025?
A: In most cases yes, as both are within the same TPS analog input module family. However, verify the revision suffix and backplane slot assignment in your system’s I/O database before swapping.
Q: Is this module compatible with Experion PKS?
A: The 51202306-010 is native to TPS/TDC 3000 architecture. Migration to Experion PKS requires Honeywell’s Series C I/O or FIM migration adapters. Contact us for migration support.
Q: Do you supply tested or untested units?
A: Konmask.com supplies tested units only. Each module passes power-on self-test and analog channel validation before dispatch.
Q: Can I get a certificate of conformance?
