Allen-Bradley 1746-A10 is a 10-slot modular CPU chassis for the SLC 500 family, designed to host processors, I/O and communications modules on a single backplane to support scalable control systems. This package includes the 1746-P2 system power supply, providing backplane power for the rack and attached modules. The backplane is rated for about 3.0 A at 5 VDC, and the chassis dimensions are approximately 17.5 in wide by 4.5 in high by 4 in deep, reflecting its compact 10-slot footprint. In the SLC 500 modular chassis lineup, 1746-A10 is the 10-slot option alongside other 1746-Ax models for mid-sized automation projects.
