Description
Allen-Bradley 1756-A13 is a 13-slot backplane chassis engineered for the ControlLogix and GuardLogix automation platforms. It provides the physical housing, high-speed communication bus, and power distribution paths necessary to link ControlLogix processors, I/O modules, and specialized network communication cards. Bottom line — it forms the structural foundation of your control rack.

Field Deployment & Global Logistics Insights
On a recent project involving a multi-axis manufacturing line upgrade, utilizing a 13-slot layout provided exactly enough room for split-network communication cards without requiring a secondary expansion rack. Well, technically this chassis accepts any combination of modules in any slot, but only if your total current draw across all voltage rails matches the ratings of your 1756-PA72 or PB75 power supply — though your mileage may vary depending on the thermal dissipation inside the enclosure. Check the mounting screws on the far right grounding tab during assembly to verify a low-impedance connection to your main enclosure backplate.
Shipping rigid structural backplanes internationally requires careful oversight of dimensional weight metrics. Because the 1756-A13 has a wider physical profile than standard 4- or 7-slot variants, it is packed in reinforced, vibration-resistant cartons to prevent flexing of the printed circuit backplane during multi-destination transit. We export these components under Incoterms 2020 frameworks, standardizing on FCA or CPT options, which enables procurement agents to retain direct control over international freight routing and incoming import declarations. Global trade done right creates competitive advantage.
Procurement FAQ
Can the 1756-A13 chassis house Series A, B, and C modules simultaneously?
Yes, the ControlLogix backplane architecture maintains backward compatibility across module series, provided the mechanical latching style aligns cleanly with the alignment guides.
Does this chassis ship with a power supply attached?
No, the 1756-A13 constitutes the standalone metal chassis and integrated backplane circuit board. Power supplies (such as the 1756-PA75 or 1756-PB75) must be purchased as separate line items.
What documents accompany the chassis for global border clearance?
Every international shipment includes a verified commercial invoice, a packing list detailing specific weights and HS codes, and a Certificate of Origin to facilitate border processing.
