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.
-

Tech & Buying Guide
Selecting the Right Cables for Industrial Automation: A Comprehensive Guide
Selecting the appropriate cabling infrastructure is critical for the success of any industrial automation project. Improper cable selection often leads to signal degradation, system instability, and costly downtime. As an automation engineer, I frequently see projects compromised by poor cabling choices in harsh industrial environments. This guide simplifies the complex landscape of cabling to help you make informed decisions for your PLC, DCS, and control systems.
Preventing Spurious Trips in Emergency Stop Systems: A Technical Guide
In industrial automation, the Emergency Stop (E-Stop) pushbutton is the ultimate safety line. However, relying on a single Normally-Closed (NC) contact can sometimes lead to unexpected spurious trips. As a control systems engineer, I have seen these nuisance trips halt entire production lines, causing significant downtime. Understanding why these components fail and how to implement robust architecture is essential for any reliable DCS or PLC-based safety system.
Sequencing Induction Motor Control with PLC Logic: Best Practices
In modern industrial automation, controlling a group of induction motors requires precision and safety. Uncontrolled simultaneous startup of multiple large motors often causes significant voltage dips, potentially triggering protective trips. Therefore, implementing a sequential startup and shutdown strategy is essential. This approach minimizes inrush current and ensures the system operates within established power constraints. A robust PLC program serves as the ideal engine for orchestrating these sequences.
