1715-C2 | Allen-Bradley | Backplane Extender Cable

Configured for backplane communication extension in I/O system platforms, the Allen-Bradley 1715-C2 (1715-C2 Backplane Extender Cable) provides direct physical execution of data and power bridging between chassis segments.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The 1715-C2 cable maintains the signal integrity required for deterministic backplane bus communication velocity across expanded I/O racks. By ensuring consistent impedance across the 2 m length, the extender cable supports the I/O density scaling necessary for complex control architectures. The cable assembly is engineered to minimize signal attenuation and crosstalk, which is required to prevent communication errors in systems where firmware flash compatibility relies on robust data transmission between the primary controller and remote chassis segments.

Frequently Asked Questions

Q: Does this cable require specific shielding or grounding considerations?

A: The 1715-C2 is designed to carry signals between chassis backplanes. Ensure that the associated chassis are effectively bonded to a common ground reference to prevent ground loop currents from flowing through the cable shield.

Q: Is it permissible to exceed the 2 m length by daisy-chaining multiple 1715-C2 cables?

A: No, daisy-chaining is not supported. Exceeding the specified cable length will introduce significant signal propagation delay and impedance mismatch, leading to backplane bus timeouts and system-wide communication failures.

Field Installation Guidelines

1. De-energize the entire I/O system prior to connecting or disconnecting the cable from the backplane ports.
2. Align the connectors carefully to avoid bending the interface pins; ensure the latching mechanism is fully secured.
3. Route the cable through dedicated, non-metallic wireways to prevent physical damage and minimize electromagnetic coupling with high-voltage AC cabling.
4. Apply a torque of 0.5 N m to the terminal screws using a 0.4 mm x 2.0 mm screwdriver to ensure secure electrical contact without damaging the connector housing.
5. Inspect the cable sheath for any signs of abrasion or environmental degradation before commissioning the expanded chassis.
