Allen-Bradley 1746-C9 SLC 500 Rack Interconnect Cable

The Allen-Bradley 1746-C9 SLC 500 Rack Interconnect Cable is a 36-inch (914.4 mm) rack interconnect designed to join multiple SLC 500 chassis in a single PLC system. Catalog number 1746-C9, this cable is intended for interconnecting SLC 500 racks such as 1746-A4, 1746-A7, 1746-A10, or 1746-A13, enabling a processor in one rack to communicate with modules in neighboring racks in a vertical stacking arrangement. At 36 inches long, it provides a direct rack-to-rack connection that supports expansion of I/O capacity within a multi-chassis configuration. Typical applications include plant automation setups that require additional racks to house more I/O or distribution hardware while maintaining a compact backplane arrangement, making it a straightforward solution for extending SLC 500 systems without adapters or custom cabling. This interconnect cable is specifically associated with the SLC 500 system and should be used in configurations that require direct rack-to-rack interconnection rather than standalone backplane connections.
