Genuine Honeywell MC-TDIY22 (51204160-175) PC Board Digital Input Field Termination | TDC3000 Series – Verified Source
The Honeywell MC-TDIY22 (Part No. 51204160-175) is a critical Digital Input Field Termination Assembly (FTA) designed for use within Honeywell’s TDC 3000 Distributed Control System architecture. As a core interface between field instruments and the DCS controller, this module is essential for reliable discrete signal acquisition in process-critical environments including refining, petrochemical, and power generation facilities. Due to its age, specialized application, and limited production runs, the MC-TDIY22 is increasingly difficult to source — and the market for counterfeit or refurbished-as-new DCS components is well-documented, posing serious risks to plant safety and uptime.
At Konmask, every Honeywell MC-TDIY22 unit we supply is sourced through verified industrial channels and subjected to our in-house quality verification protocol before dispatch. We do not list, sell, or ship any component we cannot authenticate. Our commitment to genuine, verified, and authentic parts is not a marketing claim — it is the operational standard that industrial buyers depend on when sourcing legacy DCS hardware.

Our 4-Step Quality Verification Process
Every MC-TDIY22 unit shipped by Konmask passes through the following verification stages before dispatch:
Step 1 — Visual & Physical Inspection: Full board-level inspection for component integrity, PCB condition, connector pin alignment, label authenticity (part number, revision, date codes), and absence of rework, burn marks, or counterfeit indicators. Reference photos are retained on file.
Step 2 — Functional Bench Test: Where test equipment is available, the module is powered and channel-level signal response is verified. Test results are documented and available as a Test Report upon request.
Step 3 — Documentation Cross-Check: Part number, revision level, and serial/batch codes are cross-referenced against Honeywell’s published documentation and known-good reference units. A Certificate of Conformance (COC) is issued for each shipment.
Step 4 — Packaging & Traceability: Units are packed in anti-static ESD bags, cushioned in foam-lined cartons, and shipped with a full Packing List and Country of Origin (COO) Declaration. All shipment records are archived for post-delivery traceability.
Key Features & Benefits
- Genuine OEM Hardware: Sourced from verified industrial channels — not refurbished, relabeled, or third-party clones.
