Product Details
Product Overview
The Allen Bradley 1746-A13 provides the structural and electrical foundation for large-scale SLC 500 control systems. This 13-slot chassis houses the processor, power supply, and up to 12 additional I/O or communication modules. It facilitates high-speed data exchange across the backplane while ensuring rigid mechanical alignment for all system components. We supply this unit as 100% Brand New original factory stock, guaranteeing the structural integrity and electrical conductivity required for long-term industrial deployments.

Engineering Advantages
-
High-Density Slot Allocation: The 1746-A13 offers the maximum slot count available in the SLC 500 family. By providing 13 slots, this chassis allows engineers to centralize complex I/O configurations into a single rack, reducing the need for expansion cables and secondary power supplies in large-scale applications.
-
Robust Backplane Current Capacity: The chassis supports a massive 10 Amps at 5.1V DC. This high current rating accommodates power-hungry specialty modules, such as high-speed counters or network scanners, without risking voltage drops or backplane instability.
-
Vertical Chassis Interconnectivity: For systems exceeding 13 slots, the 1746-A13 supports vertical connections with other 1746 chassis using the 1746-C9 expansion cable. This modular approach allows for system growth while maintaining a compact vertical footprint within the control cabinet.
-
Enhanced Thermal Stability: The open-style panel mount design promotes natural convection cooling. With an operating range up to 60 °C, the chassis maintains electrical timing and signal integrity even when fully populated with high-load I/O modules in warm industrial environments.
FAQs
-
Can I mount the 1746-A13 in a standard 19-inch server rack?
The 1746-A13 utilizes a panel-mount design with 8 mounting tabs intended for direct installation onto a sub-panel. To install it in a 19-inch rack, you must use a specialized rack-mount adapter bracket.
-
How do I calculate the power supply requirements for this 13-slot rack?
Sum the backplane current draw of the processor and every I/O module you intend to install. Ensure the total does not exceed the 10A (5.1V) or 2.88A (24V) limit of the chassis, and select an SLC 500 power supply (e.g., 1746-P1, P2, P3, or P4) that meets these requirements.
-
What is the maximum distance allowed between two 1746-A13 chassis?
When interconnecting chassis vertically via a 1746-C9 cable, you must maintain a maximum of 6 inches of space between the racks. This ensures signal timing across the expanded backplane remains within factory tolerances.
-
