Honeywell 51401477-100 / 51402455-100 / MP-DNCF02-201 – DCS Backplane Chassis Assembly | TDC-3000 & PlantScape Platform
The Honeywell 51401477-100 (also cross-referenced as 51402455-100 and MP-DNCF02-201) is a multi-slot backplane chassis assembly engineered for Honeywell’s TDC-3000 and PlantScape Distributed Control System platforms. Designed for continuous-process industries where unplanned downtime is measured in six-figure losses per hour, this chassis provides the structural backbone and high-integrity signal bus for I/O, controller, and communication modules.
Konmask.com sources this assembly through verified industrial channels, performs incoming inspection against OEM mechanical and electrical specifications, and ships with full traceability documentation — giving procurement engineers the confidence to close POs without site-visit delays.

- Multi-SKU Cross-Reference: Three interchangeable part numbers (51401477-100, 51402455-100, MP-DNCF02-201) simplify BOM consolidation across legacy and upgraded plant documentation.
System Architecture & Signal Flow
In a TDC-3000 / PlantScape architecture, this chassis assembly serves as the physical and electrical hub of an I/O rack. Field wiring terminates at I/O modules seated in the chassis slots; the backplane bus routes analog and digital signals to the controller module (e.g., HPM or PM) via the Local Control Network (LCN) or Universal Control Network (UCN). Power distribution rails within the chassis supply regulated DC to each seated module, while the chassis frame provides a common ground reference and EMI shielding path.
Sourcing & Quality Verification
- Source: Decommissioned plant surplus and authorized industrial distributors — no gray-market or counterfeit channels.

Technical FAQ
Q: Are 51401477-100, 51402455-100, and MP-DNCF02-201 fully interchangeable?
A: Yes. These three part numbers reference the same physical assembly at different points in Honeywell’s revision and cross-reference history. They share identical mechanical dimensions, backplane pinout, and electrical ratings.
Q: Is this chassis compatible with Experion PKS?
A: This chassis is designed for TDC-3000 and PlantScape I/O racks. Experion PKS uses a different backplane architecture (Series C / EHPM). Confirm your rack generation before ordering — our engineers can assist.
Q: Can I order a tested/powered unit?
A: Powered functional testing requires module population. Contact us to discuss test requirements for critical spares programs.
Q: What is the typical lead time?
A: In-stock units ship within 2 business days of PO confirmation. Out-of-stock lead time is 2–4 weeks depending on sourcing.
Q: Do you provide MSDS or RoHS documentation?
A: RoHS compliance documentation is available upon request. MSDS is not applicable to this assembly type.
