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.
