Honeywell 51306673-200 – High-Density I/O Card | TDC 3000 DCS Platform
Engineering Background
The Honeywell 51306673-200 is a field-proven I/O card designed for the TDC 3000 Distributed Control System — one of the most widely deployed DCS platforms in refining, petrochemical, and power generation industries. This module serves as the critical interface layer between field instrumentation and the process control network, enabling reliable signal acquisition and command output across demanding industrial environments.
Product Positioning
Engineered for procurement engineers and maintenance teams requiring a direct OEM-compatible replacement or expansion module for existing TDC 3000 infrastructure. The 51306673-200 eliminates costly system migrations by extending the operational life of installed Honeywell DCS assets with a verified, specification-matched component.

System Architecture & Signal Flow
Within the TDC 3000 architecture, the 51306673-200 I/O card resides in the field interface tier, mounted in a standard TDC 3000 card cage. Field signals from transmitters, actuators, and switches are conditioned and routed through this module to the Highway Interface Module (HIM) and subsequently to the Universal Control Network (UCN) or Local Control Network (LCN). The card handles signal marshalling, isolation, and conversion, ensuring clean data presentation to the process controller.

Technical FAQ
Q: Is the 51306673-200 compatible with all TDC 3000 card cage variants?
A: The module is designed for standard TDC 3000 card cages. Confirm your cage model and backplane revision with your system documentation before ordering. Contact us if you need compatibility verification support.
Q: What is the difference between -200 and other suffix variants (e.g., -100, -300)?
A: Honeywell uses suffix codes to denote hardware revision levels or regional configuration variants. The -200 suffix indicates a specific board revision. Substitution between suffixes should only be performed after consulting Honeywell’s compatibility matrix or your system integrator.
Q: Can you provide a Certificate of Conformance (CoC)?
A: Yes. A CoC and inspection report are available upon request for MRO procurement and regulated-industry purchasing requirements.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Contact us for current inventory status and expedited shipping options.
Q: Do you accept purchase orders from EPC contractors and plant operators?
A: Yes. We work with EPCs, OEMs, and end-user plant procurement teams. Net payment terms available for qualified accounts.
