Allen-Bradley 1746-A10 Slot Rack And Power Supply Kit

The Allen-Bradley 1746-A10 Slot Rack and Power Supply Kit is a complete SLC 500 modular chassis solution built around a 10-slot backplane and a compatible power supply, designed to house and power a bank of 1746-series I/O modules in a single enclosure. The 1746-A10 is a standard 10-slot chassis in the SLC 500 modular hardware family, intended for use with 1746 I/O modules and expansion racks. This kit typically includes the 1746-A10 rack together with a 1746-P2 system power supply, which accepts 120/240 VAC input to feed the backplane and support the installed modules. In 1746 configurations, the power supply attaches in the leftmost attachment slot of the chassis, a common arrangement that simplifies wiring and power distribution across the 10 slots. Official documentation places the 1746-A10 and the 1746-P2 as part of the SLC 500 rack family, underscoring their role as a matched rack-and-power combination for organizing and powering I/O modules in a single enclosure. This setup is widely referenced in catalog and service literature as a practical solution for consolidating a 1746-based I/O footprint, making it a straightforward option when maintaining or upgrading legacy control systems that rely on SLC 500 modular hardware.
