Allen-Bradley 1794-OF4IXT Analog Output Module – FLEX I/O

Technical Dossier

Product Details And Specifications

DriveKNMS maintains a dedicated inventory of discontinued Rockwell Automation FLEX I/O modules. Inquiries are handled by engineers with direct sourcing experience in legacy automation hardware — not by a general sales desk.

Procurement Specifications

Every 1794-OF4IXT unit shipped by DriveKNMS passes a documented inspection process before dispatch. Our quality assurance protocol covers the following checkpoints:

• Electrolytic capacitor assessment: Aging capacitors are the primary failure mode in stored analog output modules. Each unit is inspected for capacitor bulge, leakage, and ESR deviation.
• Firmware version verification: Where applicable, firmware revision is confirmed and documented to ensure compatibility with the target control system.
• Pin and connector inspection: Backplane connector pins are examined under magnification for oxidation, mechanical deformation, and contamination.
• Functional output test: Analog output channels are exercised across the configured range to confirm signal accuracy.
• Packaging and ESD protection: Units are shipped in anti-static packaging with desiccant, suitable for long-term storage if the unit is held as a spare.

Export documentation — including commercial invoice, packing list, and certificate of origin — is provided as standard. We support payment in USD, EUR, CNY, and HKD. Shipment is via DHL Express or FedEx International Priority, with tracking provided at time of dispatch.

Sourcing discontinued Rockwell Automation hardware through standard distribution is not possible — the part is no longer manufactured. The open market for legacy FLEX I/O modules is fragmented, with significant variation in unit condition, documentation quality, and seller accountability. DriveKNMS addresses each of these procurement risks directly.

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

How do I confirm the unit condition before purchase?
Condition — new surplus or refurbished — is specified in the quotation. For refurbished units, the inspection report is available on request. We do not ship units described as "as-is" or "untested."

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.
