Compatible Replacement & Equivalent Models
If the 51205995-501 is on extended lead time or discontinued, the following alternatives are commonly used in equivalent DCS configurations:
| Model | Brand | Notes |
|---|---|---|
| 51205995-502 | Honeywell | Revised revision, functionally equivalent |
| 51204160-175 | Honeywell | Used in similar analog I/O termination assemblies |
| Generic 250Ω Shunt Kit | Third-party | Must verify tolerance ±0.1% and power rating |
Always verify compatibility with your specific I/O module and termination assembly before substitution. Contact support@konmask.com for engineering confirmation.
Why Choose the Original Model
- Factory-calibrated precision — Honeywell-spec resistance tolerance ensures signal accuracy across the full 4–20 mA range.
- Plug-and-play compatibility — Designed specifically for TDC3000 and Experion termination panels; no field modification required.
- Regulatory traceability — Original part numbers support SIL-rated loop documentation and audit trails.
- Long service life — Industrial-grade materials rated for continuous operation in process plant environments.
Typical Applications
- Analog input signal conditioning in TDC3000 High-Performance Process Manager (HPM)
- 4–20 mA loop termination in Experion PKS C200/C300 controller cabinets
- Field device interface panels in refinery, petrochemical, and power generation plants
- Retrofit and spare parts inventory for legacy Honeywell DCS installations
System Compatibility
- Honeywell TDC3000 (HPM, LCN, UCN architectures)
- Honeywell Experion PKS (R400–R520)
- Honeywell PlantScape (legacy)
- Third-party marshalling panels wired to Honeywell I/O termination assemblies
Selection Guide
Use the following criteria to confirm the correct shunt resistor kit for your application:
- Identify your I/O module — Check the termination assembly part number on the cabinet label.
- Verify resistance value — Standard 4–20 mA loops use 250 Ω; confirm with your loop drawing.
- Check revision level — Suffix -501 vs -502 may indicate hardware revision; consult Honeywell release notes.
- Confirm quantity per kit — The 51205995-501 kit typically includes multiple resistors; verify against your BOM.
- Assess condition requirement — New OEM stock recommended for SIL loops; refurbished acceptable for non-critical monitoring.
Quality Assurance & Sourcing
- All units sourced from authorized industrial distributors or verified surplus channels.
- Each kit undergoes visual inspection and resistance verification before dispatch.
- Certificate of conformance (CoC) available upon request for regulated applications.
- Packaging preserved in original or equivalent ESD-safe materials.

Replacement & Compatibility FAQ
Q: Can I use a generic 250 Ω resistor instead of 51205995-501?
A: Technically possible for non-critical loops, but not recommended for SIL-rated or certified loops. The OEM kit ensures correct physical form factor and termination method.
Q: Is 51205995-502 a direct drop-in replacement?
A: In most cases yes, but verify with your Honeywell system integrator or check the Honeywell product change notice (PCN) for your specific revision.
Q: Do you provide a warranty?
A: New OEM units carry the standard Honeywell warranty. Refurbished units carry a 90-day Konmask functional warranty.
Q: Can you supply a full termination assembly instead?
A: Yes — contact us with your cabinet model and we can quote the complete assembly.
