Honeywell DC-TAIX61 DC-TAIX51 DC-TAOX51 DC-TAOX61 Analog I/O Module – TDC Series

Technical Dossier

Product Details And Specifications

The Honeywell TDC series analog I/O modules — DC-TAIX61, DC-TAIX51, DC-TAOX51, and DC-TAOX61 — are core field interface components in Honeywell's TotalPlant Solution (TPS) and TDC 3000 distributed control systems. These modules are widely deployed in oil & gas, petrochemical refining, pulp & paper, and power generation facilities worldwide. As Honeywell progressively migrates its installed base toward Experion PKS, these TDC-series modules have entered a phase of constrained availability — making procurement timing and source verification critical decisions for plant maintenance teams.

Procurement Specifications

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Avoiding Counterfeit Risk: The TDC module market has a documented counterfeit problem. Procurement teams sourcing from unverified marketplaces risk receiving modules with falsified firmware, degraded capacitors, or non-original PCB assemblies. DriveKNMS applies a multi-point inspection protocol including visual verification, functional bench testing, and serial number cross-referencing before dispatch review.

• Condition review: Available condition, photos, test records and documentation are checked before quotation according to the requested model.
• Export Documentation: Full commercial invoice, packing list, certificate of origin, and export license (where applicable) provided for all international shipments. Compliant with CN customs export regulations and destination country import requirements.
• Multi-Currency Payment: USD, EUR, HKD, CNY accepted. T/T (wire transfer), PayPal, and LC (Letter of Credit) for orders above USD $10,000.
• Global Logistics: DHL Express, FedEx International Priority, and UPS available. Typical transit times: 3–5 days to Europe/North America, 2–4 days to Southeast Asia and Middle East. Air freight tracking provided for all shipments.
• Packaging: ESD-safe anti-static packaging with foam cushioning. Original OEM packaging preserved where available.

Part Number Verification & Cross-Reference: Our technical team cross-references customer-provided part numbers against Honeywell's official documentation to prevent ordering errors. If your engineering team has identified a compatible substitute (e.g., DC-TAIX61 replacing DC-TAIX51 in certain configurations), we will confirm compatibility before processing your order.

Q: How are commercial terms confirmed?
A: Commercial terms are confirmed during RFQ review based on model, quantity, destination, documentation and sourcing route.

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.

Q: Can you source modules that are listed as discontinued by Honeywell?
A: Yes. Our specialty is legacy and end-of-life industrial components. We source from surplus inventory, decommissioned plant equipment (fully tested), and our global distributor network. Availability is confirmed before any order is accepted.
