Schneider 140XCA71709 Backplane Expander Cable

FAQ

Q1: What systems is the 140XCA71709 cable designed to work with?
A1: It is designed specifically for Modicon Quantum systems to extend the backplane connection between racks.

Q2: Can this cable support high-speed backplane data signals?
A2: Yes, the cable is engineered to maintain Quantum backplane signal integrity across its 3-meter length.

Q3: Does the cable require any additional termination hardware?
A3: No, it comes with factory-terminated connectors ready for direct installation.

Q4: Is there a maximum number of racks that can be linked using expander cables?
A4: Yes, Quantum systems have a defined limit on remote expansion segments; this depends on the specific CPU and rack configuration.

Q5: Can the 140XCA71709 be used interchangeably with other Quantum expander cable lengths?
A5: It can be used where a 3-meter length is appropriate, but it must match Schneider’s approved cable part numbers for reliable operation.

Q6: Are there restrictions on bending radius during installation?
A6: Yes, like most industrial cables, it should not be sharply bent; maintaining a gentle radius preserves signal quality and cable life.

Q7: Is shielding included to reduce electrical noise?
A7: The cable incorporates shielding necessary for stable Quantum backplane communication.

Q8: Does the cable support hot-swap of racks during system operation?
A8: Backplane expander cables themselves do not enable hot-swap; whether racks can be removed depends on the system’s configured redundancy and controller behavior.
