The Allen-Bradley 1746-C9 is a 36-inch (3-foot) ribbon-style interconnect cable engineered for the SLC 500 modular control system. This cable facilitates reliable communication between the primary processor chassis and secondary or tertiary expansion chassis within an industrial enclosure. It is a critical component for systems requiring distributed I/O across multiple racks, ensuring seamless data transfer between the SLC 5/01, 5/02, 5/03, 5/04, or 5/05 processors and remote I/O modules.
Features
System Expansion: Enables multi-chassis configurations, supporting up to 3 chassis in a single local system.
Compatibility: Fully compatible with all modular 1746 chassis, including 1746-A4, 1746-A7, 1746-A10, and 1746-A13.
Flexible Routing: Designed for chassis spacing between 6 and 36 inches, allowing for versatile panel layout and installation.
Robust Design: Ribbon-style construction optimized for industrial environments with a defined bend radius for durability.

Installation Guidelines
Power Down: Always disconnect power from the SLC 500 system before connecting or disconnecting the chassis interconnect cable to prevent electrical damage.
Bend Radius: Ensure the cable is not bent tighter than the 101.6 mm (4-inch) minimum radius to avoid damaging the internal ribbon conductors.
Routing: Route the cable away from high-voltage AC lines and heavy electromagnetic interference (EMI) sources to maintain signal integrity.
Seating: Ensure the connectors are fully seated and locked into the chassis ports. Avoid applying excessive tension or pulling force on the cable ends.
FAQ
Can the 1746-C9 be used to connect more than three chassis?
No, the SLC 500 system architecture typically supports a maximum of three chassis (one local and two expansion) in a single local system configuration.
Is this cable compatible with all SLC 500 chassis?
Yes, the 1746-C9 is designed for use with all modular 1746 chassis, including the 4, 7, 10, and 13-slot versions.
