Allen-Bradley 1746-A10 10-Slot SLC Rack Chassis

The Allen-Bradley 1746-A10 is a 10-slot SLC 500 modular rack chassis for the Rockwell Automation SLC System, providing a back-plane that accepts up to ten 1746 I/O modules in a single enclosure. It is designed for back-panel mounting in control cabinets and measures about 171 mm high, 397 mm wide, and 145 mm deep (6.73 in x 15.64 in x 5.71 in), with a weight of roughly 1.5 kg (3.3 lb). This chassis exemplifies the SLC System’s 10-slot modular hardware style, enabling compact, organized expansion of legacy I/O without redesigning the rack. Common applications include machine control and process monitoring setups that rely on a Rockwell Automation SLC 500 controller paired with 1746 I/O modules in a single enclosure, helping keep wiring neat and modules serviceable in the same rack.
