Allen-Bradley 1746-A13 is a 13-slot backplane chassis for the SLC 500 modular I/O family, serving as the backbone that mounts and interconnects 1746 I/O modules in a single back-panel enclosure. The backplane is rated to carry up to 13 A at 5.1 VDC and 3.71 A at 24 VDC, enabling the distributed power and signaling required by SLC 500 I/O modules. Its physical dimensions are 6.73 inches high, 19.78 inches wide, and 5.71 inches deep (171 x 502 x 145 mm) and it weighs about 4.2 pounds (1.9 kg), with back-panel mounting for straightforward installation in control cabinets. The 1746-A13 is designed to host a 13-slot SLC 500 rack, supporting SLC 500 I/O modules, including digital and analog types, in industrial automation applications.
