Allen-Bradley 1746-A10 SLC 500 Modular Chassis

The Allen-Bradley 1746-A10 is a 10-slot modular chassis for the SLC 500 PLC family, providing a backplane-based frame to house processors, I/O adapters, and expansion modules in a scalable control system. Measuring about 6.73 x 15.34 x 5.71 inches and weighing roughly 3.3 lb (1.5 kg), the chassis is designed for back-panel mounting in a control cabinet. The backplane supports 5.1 VDC at up to 10 A and 24 VDC at up to 2.88 A to power installed modules, helping ensure stable operation for CPUs and I/O cards. As part of the SLC 500 modular hardware style, the 1746-A10 accepts a range of processors and I/O modules in a single 10-slot rack, enabling configurations that mix control, communication, and I/O tasks within a compact footprint. Common applications include small-to-medium automation projects requiring a modular, upgradeable PLC chassis for baseline SLC 500 systems, machine control, and process automation where reliable, Allen-Bradley-branded hardware is preferred.
