Allen-Bradley 1746-A13 Printed Circuit Board Assembly

Allen-Bradley 1746-A13 is a 13-slot SLC 500 modular system chassis backplane that serves as the expansion backbone for Rockwell Automation’s SLC 500 family. This Series 1 chassis provides 13 plug-in slots and is designed for back-panel mounting in a compact enclosure. Its dimensions are 6.73 inches wide, 19.78 inches deep, and 5.71 inches high, with a shipping weight of approximately 4.2 pounds (1.9 kilograms). Cataloged as 1746-A13, the backplane is built to accommodate a range of 1746-series I/O modules within a modular SLC 500 system, enabling scalable expansion of discrete and analog I/O when paired with the appropriate power supply and processor in a complete installation. The 1746-A13 backplane relies on standard SLC 500 hardware specifications, ensuring compatibility with the familiar plug-in module ecosystem and straightforward integration into existing Rockwell Automation control architectures. This backplane is suitable for installations where a back-panel mounted 13-slot chassis is required to consolidate controllers and I/O cards in a single enclosure.
