System Architecture & Signal Flow
Within the TDC 3000 / TPS architecture, the 51304901-100 HWD C I/O Module resides in the I/O Link subsystem, interfacing field transmitters and actuators to the High-Performance Process Manager (HPM) or Process Manager (PM) controller via the Local Control Network (LCN) or Universal Control Network (UCN) backplane.
Signal Flow: Field Device → Field Termination Assembly (FTA) → 51304901-100 HWD C I/O Module → HPM/PM Controller → LCN/UCN Data Highway → Operator Console (US/GUS/TPS Console)
This module handles signal conditioning, A/D or D/A conversion, and data formatting before passing process values to the controller for PID loop execution and alarm management.

Technical FAQ
Q: Is the Honeywell 51304901-100 compatible with Experion PKS?
A: The 51304901-100 is native to TDC 3000 / TPS architecture. Experion PKS uses a different I/O subsystem (CIOM-A, LLMUX, etc.). Migration adapters may be required – consult your Honeywell system integrator.
Q: Can this module be used as a direct replacement for a failed unit in an HPM rack?
A: Yes, in most cases the 51304901-100 is a direct slot-for-slot replacement within compatible HPM I/O link configurations. Verify rack slot assignment and FTA wiring before installation.
Q: What is the lead time for this part?
A: Standard lead time is 3–7 business days for in-stock units. Contact us for current availability.
Q: Do you provide a test report?
A: Yes. A functional test report is available upon request at time of order.
Q: What certifications does this module carry?
A: The module is certified as part of the Honeywell TDC 3000 system, which carries CE, UL, and CSA system-level approvals. Individual module markings may vary by revision.
