Description
The Allen-Bradley 1746-C9 is a specialized 36-inch (0.91-meter) ribbon interconnect cable engineered for the SLC 500 modular control system. This component facilitates reliable communication and power distribution between multiple chassis within an industrial control cabinet, enabling the expansion of I/O capacity across secondary or tertiary rack configurations.
Features
-
System Expansion: Supports the daisy-chaining of SLC 500 modular chassis (1746-A4, A7, A10, A13) to extend system I/O beyond a single rack.
-
Optimal Length: Provides a 3-foot reach, ideal for cabinets where chassis are mounted in stacked or adjacent configurations.
-
Compatibility: Fully compatible with SLC 5/01, 5/02, 5/03, 5/04, and 5/05 processor-based systems.
-
Robust Design: Ribbon-style construction ensures secure signal integrity between backplanes while maintaining flexibility for routing within tight enclosure spaces.
Applications
This cable is intended for use in Allen-Bradley SLC 500 installations requiring multi-chassis expansion. It is commonly deployed in manufacturing environments where I/O requirements necessitate additional rack space beyond the primary processor chassis.

Installation Guidelines
- Ensure the PLC system power is disconnected before installing or removing the interconnect cable.
- Align the ribbon cable connectors carefully with the backplane ports on both chassis to prevent pin damage.
- Maintain the minimum bend radius of 101.6 mm to avoid stress on the internal ribbon conductors.
- Route the cable away from high-voltage wiring, AC power lines, and sources of significant electromagnetic interference (EMI).
- Verify that all chassis are properly grounded to the enclosure backplane to ensure signal stability.
FAQ
What is the maximum distance supported by the 1746-C9?
The cable is designed for a maximum reach of 36 inches, allowing for flexible mounting of chassis within an enclosure while maintaining required signal integrity.
Can I use this cable with any SLC 500 chassis?
Yes, the 1746-C9 is compatible with all modular 1746 chassis, including the 4-slot (A4), 7-slot (A7), 10-slot (A10), and 13-slot (A13) versions.
