Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or functional equivalents for the 51304483-100. Always verify firmware revision, channel count, and HPM slot compatibility before substitution:
- 51304483-150 — Revised hardware revision of the same base module; direct drop-in candidate. Confirm suffix compatibility with your HPM firmware version.
- 51304483-200 — Higher-revision variant; may include HART pass-through enhancement. Verify HPM IOM revision requirements.
- 51309276-175 / 51309276-225 — Analog Output modules from the same TDC 3000 HPM I/O family; cross-reference channel count and signal range before substitution.
- 51401544-175 — Analog Output module used in Honeywell Experion PKS migration kits; suitable for hybrid TDC 3000 / Experion architectures.
- Honeywell Experion C300 AO Module (51309276-xxx series) — For sites migrating from TDC 3000 to Experion PKS; requires migration engineering and I/O termination adapter.
- Third-party HART AO modules (Moore Industries, Pepperl+Fuchs) — Field-mount alternatives for individual loop replacement; not rack-compatible but viable for isolated channel failures.
⚠ Substitution Note: Honeywell HPM modules use firmware-linked hardware revisions. Always match the suffix (-100, -150, -200) to your HPM firmware release. Contact Konmask engineering for cross-reference confirmation.
Why Choose the Original Model
- Zero Configuration Risk: The 51304483-100 is a certified OEM module — no firmware changes, no HPM database modifications, no re-commissioning required for like-for-like replacement.
- Validated Signal Integrity: Factory-calibrated 4–20 mA output with Honeywell-certified accuracy; eliminates field calibration risk during emergency replacement.
- HPM Slot Compatibility Guaranteed: Designed to the exact HPM I/O Link electrical and mechanical specification — no adapter, no rework.
- Regulatory Compliance Continuity: Maintains existing SIL, FM, and CE certifications for safety-instrumented and hazardous-area installations without re-validation.
- Long-Term Spare Parts Strategy: Stocking OEM modules reduces lifecycle risk for TDC 3000 systems with 10–20+ year remaining service life.
Typical Applications
- Refinery crude distillation and hydrocracking unit control loops

- Rack Compatibility: HPM I/O Link racks (standard and extended configurations)
- Firmware Dependency: HPM firmware R500 and above (confirm suffix against your release)
- Termination Assembly: Requires matching Honeywell FTA (Field Termination Assembly) — confirm FTA model against channel count and signal type
- HART Compatibility: HART pass-through supported on applicable revisions (verify with HPM IOM documentation)
- Experion PKS Migration: Compatible with Honeywell Series C migration architecture using appropriate I/O Link bridge modules
Selection Guide
Use the following decision matrix to select the correct module for your application:
- Like-for-like emergency replacement (same HPM firmware): → Order 51304483-100 directly. No engineering review required.
- Replacement with firmware upgrade: → Evaluate 51304483-150 or -200. Confirm HPM firmware release notes for hardware revision compatibility.
- Channel count expansion: → Review HPM I/O Link slot budget and FTA wiring capacity before selecting higher-density AO modules.
- HART integration requirement: → Specify HART-enabled revision; confirm HPM HART multiplexer configuration.
- Migration to Experion PKS: → Engage Honeywell migration engineering or contact Konmask for Series C migration module selection.
- Budget-constrained maintenance: → Tested-used or refurbished 51304483-100 units available; condition certificate provided. Contact Konmask for stock status.
