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

The Allen-Bradley 1746-A10 is a 10-slot SLC 500 PLC rack with an integrated 1746-P2 power supply, designed to house and power SLC 500 modules in industrial control panels and automated production lines. This panel-mount rack supports a 120/240V AC input and delivers 5V DC at 10A and 24V DC at 2.88A from the built-in supply, with a backplane that follows the SLC 500 backplane bus for reliable module communication. Key specifications include a 10-slot chassis, panel mounting, IP20 protection, operating temperature 0°C to 60°C, and storage from -40°C to +85°C, along with UL, CSA, and CE compliance. The unit is commonly used by maintenance teams, OEMs, and system integrators for system expansion, retrofit projects, and replacement of legacy PLC racks and power supplies in manufacturing lines, packaging machines, material handling, and process control applications where stable power distribution and backplane communication are essential. Common replacements include the Allen-Bradley 1746-A13 rack with 1746-P2 power supply, the 1746-A7 rack with 1746-P1 power supply, and Siemens S7-300 rack with PS307 power supply.
