Allen-Bradley 1771-OB Digital Output Module – PLC-5 Series

Technical Dossier

Product Details And Specifications

DriveKNMS reviews sourcing options for this model through RFQ handling before quotation.

Procurement Specifications

Spare Part Turnover Rate: For plants still running PLC-5 systems, the 1771-OB typically has a moderate-to-high turnover rate due to output transistor degradation over time. Procurement teams should maintain a minimum buffer of 1–2 units per active chassis to avoid reactive sourcing at inflated spot prices.

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

• Shipping carriers: DHL Express, FedEx International Priority — typical transit 2–5 business days globally
• Payment methods: T/T (bank wire), PayPal, Western Union, L/C for large orders
• Multi-currency support: USD, EUR, GBP, HKD, CNY
• Export compliance: All shipments comply with applicable export control regulations (EAR/ECCN classification available on request)

We are not a catalog distributor. DriveKNMS operates as an industrial component sourcing specialist — which means when your internal channels come up empty, we activate a network of 200+ verified suppliers across North America, Europe, and Asia to locate your part.

• Part number cross-reference: We identify compatible alternatives (e.g., 1771-OBD, 1771-OBN) when the exact revision is unavailable, with full technical comparison provided before you commit.
• Selection error correction: Our technical team reviews your application requirements before confirming compatibility — reducing the risk of ordering the wrong revision or voltage range.
• Repeat order management: Clients with ongoing PLC-5 maintenance programs can establish a standing RFQ arrangement for priority sourcing and price lock agreements.

Q: Can you source specific firmware revisions or hardware series?
A: We will specify the revision available at time of quote. If a specific revision is required for your application, please state this in your RFQ and we will confirm availability before invoicing.
