Application and Installation
The 1746-C7 is specifically designed for side-by-side chassis mounting. Because the cable length is fixed at 6 inches, it provides the lowest possible impedance for high-speed data transfer between the CPU chassis and the expansion chassis. For vertical mounting or wider spacing, engineers should consider longer variants like the 1746-C9.
Frequently Asked Questions
-
Does the 1746-C7 require a separate power supply?
No, the cable draws its operating current (110mA @ 5V / 85mA @ 24V) directly from the SLC backplane power supply.
-
Can I hot-swap this cable while the PLC is running?
It is strongly recommended to remove all system power before installing or removing the 1746-C7 to prevent backplane shorts or data corruption.
-
Is the 1746-C7 shielded?
Yes, it features industrial-grade shielding to protect the sensitive backplane bus signals from electromagnetic interference (EMI) typical in factory environments.

Tech & Buying Guide
Choosing the Right Controller: PLC vs. Motion Controller in Industrial Automation
Selecting the optimal control architecture is a foundational decision in industrial automation. Engineers must frequently choose between a Programmable Logic Controller (PLC) and a dedicated Motion Controller. While both systems manage machinery, their underlying design philosophies differ significantly, impacting performance, scalability, and system integration.
Mastering PLC Power Supply Architectures and Operating Voltages
Selecting the correct operating voltage is a critical step in designing reliable industrial automation systems. Whether you are working with a compact PLC or a large-scale DCS, your power architecture dictates the system's longevity. In this guide, we explore the standard voltage ranges and power distribution strategies required to maintain stable factory automation operations.
Optimizing Power Supply Sizing for Industrial Automation Systems
The power supply is the silent heartbeat of any industrial automation system. While engineers often prioritize processors and communication protocols, a stable power architecture remains the most critical factor for long-term reliability. In my 15 years of experience, I have found that neglecting power supply sizing often leads to ghost errors, intermittent field device failures, and costly production downtime.
