Information About 1746-A4
The 1746-A4 is part of the Allen-Bradley SLC 500 family from Rockwell Automation, developed as a modular chassis for small to medium control applications. It features four slots for I/O modules and mounts directly on a back panel using integrated mounting tabs. The chassis requires a power supply installed on the left end panel and can be used alone or interconnected with up to two additional chassis using chassis interconnect cables (1746-C7, 1746-C9, or 1746-C16). With these connections, a maximum of 30 I/O slots can be configured. Built with a maximum backplane current of 5.1 VDC at 10 A and 24 VDC at 2.88 A, the unit ensures proper power distribution to installed modules. Designed for industrial environments, the 1746-A4 supports operation in temperatures from 0 to 60 °C (32 to 140 °F) with 5–95% relative humidity, making it a durable and reliable component in automation systems.
Key Features:
- Design: Modular 4-slot chassis with compact dimensions for flexible installation.
- Connectivity: Supports Allen-Bradley 1746 I/O modules with integrated backplane connections.
- Power Distribution: Provides up to 10 A at 5.1 VDC and 2.88 A at 24 VDC for modules.
- Compatibility: Works with SLC 500 processors, I/O, and specialty modules.
- Mounting Style: Panel-mounted with integrated tabs for secure installation.
- Expansion: Allows interconnection of up to three chassis, supporting a total of 30 slots.
- Durability: Operates in 0–60 °C with up to 95% non-condensing humidity for industrial reliability.
- Application Range: Suitable for PLC-based machine control and automation systems.
The 1746-A4 delivers the reliability and precision required for industrial automation and control applications.
