Allen-Bradley 1746-A10 SLC 500 10-Slot Rack Assembly

Allen-Bradley 1746-A10 SLC 500 10-Slot Rack Assembly is a ten-slot backplane chassis for the SLC‑500 modular PLC family, designed to house a processor, I/O modules, and optional communications cards in a single expansion rack. The 10-slot chassis (catalog 1746-A10) enables scalable control configurations within a compact footprint and is intended for use with standard SLC‑500 modules. When paired with the included 1746-P2 power supply, the rack provides backplane power with 120/240 VAC input and delivers 5 A at 5 V DC to the backplane and 0.96 A at 24 V DC for control circuits. This combination supports the full range of 1746-series I/O and processor modules, allowing configurations from simple to moderately complex automation tasks. Typical applications include small to mid-size machine control, packaging lines, conveyors, and other discrete automation projects where a modular, serviceable PLC solution is advantageous. The assembly simplifies wiring and maintenance by using a plug-in, backplane-based architecture that accommodates mixed module types across the ten slots in accordance with SLC‑500 module compatibility.
