Description

The Allen-Bradley 1746-C16 is a specialized ribbon cable designed for multi-chassis configurations within the SLC 500 modular control system. Measuring 1.22 meters (4 feet / 50 inches), this cable provides the necessary reach to connect a primary processor chassis to expansion chassis within the same industrial enclosure. It ensures reliable backplane communication, allowing the SLC 500 processor to manage I/O modules located in secondary racks.

Features

  • System Compatibility: Specifically designed for Allen-Bradley SLC 500 modular chassis systems.
  • Extended Reach: Longest available interconnect cable for the SLC 500 platform at 1.22 meters.
  • Robust Construction: Rigid ribbon cable design featuring integrated strain relief for industrial durability.
  • Keyed Connectors: Engineered with physical keys to ensure correct orientation and prevent improper backplane connection.

Applications

This cable is essential for expanding SLC 500 systems beyond a single rack. It is typically used in control cabinets where I/O requirements exceed the capacity of a single chassis, allowing for vertical or side-by-side expansion of the PLC architecture.

Installation Guidelines

  • Power Status: Always ensure the system power supply is disconnected before installing or removing the interconnect cable.
  • Orientation: The connector with the key on the top must be inserted into the right-hand socket of the exit chassis. The connector with the key on the inside must be inserted into the left-hand socket of the expansion chassis.
  • Clearance: Ensure a minimum bend radius clearance of 101.6 mm (4 inches) to prevent cable damage and signal interference.
  • Sequence: It is recommended to route and connect the cable before installing power supplies to ensure sufficient physical space and clearance.

FAQ

Is the 1746-C16 compatible with all SLC 500 chassis?

Yes, the 1746-C16 is designed for use with standard SLC 500 modular chassis to facilitate multi-rack communication.

Can I use this cable to connect more than three chassis?

No, the SLC 500 system architecture typically supports a maximum of three total chassis (one primary and two expansion) when using these interconnect cables.
