Allen-Bradley 1746-A10 SLC 500 10-Slot I/O Chassis

Product Overview

The Allen-Bradley 1746-A10 functions as the backbone for SLC 500 modular hardware systems. This 10-slot chassis provides the physical framework and electrical backplane necessary for housing 1747 processors and various 1746 I/O modules. It facilitates high-speed communication and power distribution across the backplane, ensuring seamless data exchange between the CPU and field devices. Despite manufacturer discontinuation, we provide this unit as 100% Brand New and Original, ensuring your legacy systems maintain peak performance without the risks associated with used or refurbished hardware.

Technical Specifications

The 1746-A10 utilizes a robust backplane design to support complex automation architectures:

Engineering Advantages

• High-Density Integration: The 10-slot configuration maximizes cabinet space efficiency by allowing the consolidation of up to ten distinct I/O or specialty modules into a single footprint.

• Rugged Backplane Power: With a 10 A capacity at 5.1 VDC, the backplane drives power-hungry analog and specialized communication modules without voltage drops, maintaining signal integrity across the entire rack.

• Simplified Panel Installation: The integrated mounting tabs allow for direct panel mounting using standard screws. Its dimensions (39.7 cm width) fit standard industrial enclosures, simplifying the transition from smaller 4 or 7-slot racks.

• Legacy System Protection: Using a brand-new 1746-A10 eliminates intermittent bus errors often caused by the degraded connectors or corroded traces found in used equipment, extending the operational life of existing SLC 500 installations.

FAQs

• Q: Does the 1746-A10 include the power supply?

• A: No. You must install a compatible SLC 500 power supply (such as the 1746-P1, P2, or P4) on the left side of the chassis to energize the backplane.

• Q: Can I mix different types of 1746 modules in this rack?

• A: Yes. The chassis supports a mix of digital, analog, and specialty modules. Ensure your total current draw does not exceed the 10 A @ 5.1 VDC or 2.88 A @ 24 VDC limits.

• Q: Is this a "New-in-Box" (NIB) unit or a refurbished rack?

• A: This is 100% Brand New original hardware. We do not sell "pulls" or "refurbished" units, ensuring you receive the full reliability of factory-clean gold-plated backplane connectors.

• Q: What is the proper procedure for mounting the chassis in a high-vibration environment?

• A: Use all mounting holes provided on the chassis flange and ensure the panel is rigid. Additionally, use the module's integrated locking tabs to secure each I/O card firmly into the 10-slot backplane.
