The Allen-Bradley 1746-A10 is a 10-slot modular chassis designed for the SLC 500 programmable logic controller system. This chassis provides the physical mounting and electrical backplane communication required to support up to ten SLC 500 I/O or specialty modules. It serves as the backbone for the controller rack, facilitating power distribution and data exchange between the processor and the connected I/O modules.
Features
10-slot capacity for flexible I/O configuration.
Designed specifically for the Allen-Bradley SLC 500 system architecture.
Robust mechanical design for secure module seating and vibration resistance.
Integrates directly with the SLC 500 power supply and processor modules.
Applications
This chassis is used in industrial automation environments requiring a scalable and reliable I/O rack system. It is commonly utilized in manufacturing, process control, and machine automation where multiple I/O modules need to be managed by a single SLC 500 processor.

Installation Guidelines
Ensure the chassis is mounted on a flat, clean, and vibration-dampened surface within an appropriate industrial enclosure.
Verify that the power supply is disconnected before installing or removing any I/O modules from the chassis backplane.
Ensure proper grounding of the chassis to the enclosure backplane to minimize electromagnetic interference (EMI).
Maintain adequate clearance around the chassis to allow for proper airflow and cooling, preventing heat buildup within the rack.
When inserting modules, ensure they are properly aligned with the backplane connector and fully seated before tightening the retaining screws.
FAQ
What is the primary function of the 1746-A10?
The 1746-A10 is a 10-slot chassis that provides the electrical backplane and mechanical housing for SLC 500 processor and I/O modules.
Is this chassis compatible with all SLC 500 modules?
Yes, the 1746-A10 is designed to support standard 1746-series I/O modules used within the SLC 500 platform.
Does this unit include a power supply?
No, the 1746-A10 is a chassis only. The power supply must be ordered separately and is typically mounted to the side of the chassis.
