Compatible Replacement & Equivalent Models
When the 51402089-100 EPDG2 is unavailable or end-of-life, the following models may serve as functional replacements depending on your system revision and firmware version. Always verify compatibility with your system integrator before substitution.
- 51402089-150 — Revised hardware revision of the same EPDG2 series; direct drop-in for most TDC 3000 cabinets
- 51401642-100 — Earlier EPDG generation; compatible in legacy TDC 3000 R500+ environments
- 51402089-200 — Enhanced variant with extended diagnostics; check firmware compatibility
- 51304754-150 (HPMM) — High-Performance Multifunction Module; applicable in hybrid migration scenarios
- Third-party equivalents: Select certified aftermarket suppliers offer functionally equivalent cards tested to Honeywell OEM specifications — contact Konmask for vetted options
Why Choose the Original Model
- OEM Firmware Compatibility: The 51402089-100 is validated against Honeywell TDC 3000 firmware revisions R400–R640, ensuring zero integration risk
- Proven Field Reliability: Widely deployed in refining, petrochemical, and power generation plants globally
- Honeywell Support Ecosystem: Eligible for Honeywell lifecycle support, spare parts programs, and certified repair services
- Regulatory Compliance: Meets IEC 61511 functional safety requirements for SIL-rated process control loops
Typical Applications
- Oil & Gas upstream/downstream process control
- Petrochemical and chemical plant DCS networks
- Power generation (coal, gas, nuclear auxiliary systems)
- Pulp & paper and water treatment automation
- Pharmaceutical batch process control
System Compatibility
- Honeywell TDC 3000 (R400 and above)
- Honeywell PlantScape (legacy integration mode)
- Honeywell Experion PKS (via legacy card cage adapter)
- LCN / UCN Network Architecture — requires matching network interface configuration
- Not compatible with Experion LS or C300 controller series without hardware adaptation
Selection Guide
Use the following criteria to confirm the 51402089-100 is the correct module for your application:
- Step 1 — Identify your DCS revision: Confirm TDC 3000 firmware is R400–R640; check the system console or engineering workstation
- Step 2 — Verify slot type: EPDG2 occupies a standard LCN card slot; confirm physical slot dimensions and backplane connector type
- Step 3 — Check network topology: Confirm LCN or UCN bus is in use; EPDG2 is not compatible with FTE (Fault Tolerant Ethernet) architectures
- Step 4 — Review revision suffix: Suffix -100 denotes the base hardware revision; if your system requires -150 or -200, contact us for cross-reference
- Step 5 — Confirm quantity and lead time: For critical spares, we recommend holding 1–2 units on-site; Konmask maintains stock for rapid dispatch

Replacement & Compatibility FAQ
Q: Can the 51402089-150 replace the 51402089-100 directly?
A: In most TDC 3000 installations, yes. The -150 revision is a hardware update with the same functional footprint. Verify with your Honeywell system engineer for safety-critical loops.
Q: Is this card compatible with Experion PKS R500?
A: The EPDG2 is a TDC 3000 legacy card. Integration into Experion PKS requires a legacy card cage and appropriate software bridge — consult Honeywell or Konmask for migration support.
Q: Do you supply tested/refurbished units?
A: Yes. All refurbished units are bench-tested and carry a 90-day replacement warranty. New surplus units are also available subject to stock.
Q: What is the lead time for out-of-stock units?
A: Typical sourcing lead time is 2–4 weeks for hard-to-find revisions. Contact us early to avoid production downtime.
Q: Can you provide a certificate of conformance?
A: Yes, CoC and test reports are available upon request for all units.
