Allen-Bradley 1746-A10 SLC 500 Programmable Logic Controller

Allen-Bradley 1746-A10 is a 10-slot modular chassis for the SLC 500 family, serving as the backplane rack that accommodates a processor module, communications adapters, and discrete or analog I/O modules to build a complete PLC control cabinet. Part of the Series 1 SLC-500 hardware family, this 10-slot chassis provides a scalable platform for assembling control configurations by inserting compatible 1746 modules such as the 1746-OB8 8-channel DC output, the 1746-IV16 16-channel 24 V DC input, and the 1746-OA16 16-channel 240 V AC triac output, among others. The chassis is specified for 0 to 60 C operation with storage temperatures from -40 to 85 C and up to 95% relative humidity, reflecting its suitability for industrial environments where ambient conditions may vary. Designed to work with a range of 1746-series processors and I/O modules, the 1746-A10 enables flexible, modular automation solutions—from straightforward machine control to more complex logic applications—while preserving familiar Rockwell Automation tooling and installation practices.
