Allen-Bradley 1756-PA72/B Power Supply – ControlLogix Series

Technical Dossier

Product Details And Specifications

The Allen-Bradley 1756-PA72/B is a 85–265V AC input power supply module for the ControlLogix 1756 chassis platform — one of the most widely deployed PLC architectures in discrete manufacturing, oil & gas, and utilities infrastructure worldwide. As Rockwell Automation continues its lifecycle management cycle, sourcing verified 1756-PA72/B units requires a supplier with both physical inventory access and the compliance infrastructure to support cross-border procurement.

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.

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.

Every 1756-PA72/B unit shipped by DriveKNMS undergoes a pre-shipment inspection protocol covering physical integrity, label authenticity, and where applicable, functional verification. We do not source from unverified secondary markets.

• Part Number Verification: We cross-reference revision codes (e.g., /B vs /A) to ensure you receive the exact firmware and hardware revision your system requires — not a substitute that creates compatibility issues
• RFQ Response Time: Formal quotations issued within 4 business hours for standard inquiries; emergency sourcing responses within 1 hour during business hours
• Financial Compliance: All transactions issued with formal commercial invoices suitable for corporate accounts payable, VAT reclaim, and audit trails
• Multi-Line Sourcing: Submit a full BOM (Bill of Materials) for your ControlLogix spares list — we handle cross-referencing, availability checking, and consolidated shipment to reduce your freight cost and administrative burden
• No Substitution Without Approval: We will never ship an alternative part number without explicit written approval from your team

Q: Can you source other 1756-series modules?
A: Yes. DriveKNMS maintains sourcing capability across the full Allen-Bradley 1756 ControlLogix product family, including I/O modules, communication cards, chassis, and processors. Submit a full spare parts list for a consolidated quote.

Q: How do I verify the authenticity of the unit I receive?
A: All units are shipped with original manufacturer labels intact. We provide high-resolution photos of the physical unit prior to shipment upon request, and our inspection report is available for units that have undergone functional testing.
