Information About 1746-A4
The 1746-A4 is part of Rockwell Automation’s SLC 500 family and serves as a modular chassis for small and mid-range control systems. It includes four slots for I/O modules and mounts securely onto a back panel using integrated panel-mount tabs. To supply power to the modules, the chassis requires a compatible SLC 500 power supply installed on the left end of the assembly. For expanded applications, up to three chassis—including the 1746-A4—can be interconnected using 1746-C7, 1746-C9, or 1746-C16 cables, allowing a total of 30 slots across multiple racks. With robust backplane current ratings and environmental durability, this chassis supports dependable operation in a wide range of industrial automation environments.
Key Features:
- Compact 4-Slot Design: Provides four module positions for processors, I/O, or specialty modules within small to medium SLC 500 systems.
- Integrated Backplane: Delivers up to 10 A at 5.1 VDC and 2.88 A at 24 VDC to support reliable module power distribution.
- Panel-Mount Construction: Includes mounting tabs for secure back-panel installation in industrial control enclosures.
- Expansion Capability: Supports interconnection of up to three SLC chassis for a combined total of 30 I/O slots.
- Broad Compatibility: Works with all SLC 500 controllers, discrete/analog modules, and specialty communication modules.
- Industrial Durability: Rated for operation from 0–60 °C with up to 95% non-condensing humidity, ensuring reliable performance.
- Standards Compliance: Meets GOST, KC, and Marine classifications for global industrial use.
- Reliable Mechanical Build: Provides a sturdy enclosure for protecting modules and maintaining stable system operation.
The 1746-A4 delivers the reliability and precision required for industrial control systems using the Allen-Bradley SLC 500 platform.
