Hardware Specifications

EtherNet/IP and Redundant I/O Infrastructure

Within the 1715 Redundant I/O architecture, the 1715-TAS0F8I functions as the field termination interface for isolated analog output channels. The assembly supports high I/O density deployments by consolidating signal wiring, fuse protection, and isolation functions into a dedicated termination platform. Its design aligns with the deterministic data handling requirements of redundant EtherNet/IP-based control infrastructures while maintaining separation between field circuits and backplane connections.

Frequently Asked Questions

Q: Does the 1715-TAS0F8I provide individual channel protection?
A: Yes. The assembly incorporates a 50 mA fuse for each output channel, providing independent protection against field-side overload conditions.

Q: Can unshielded conductors be used for analog output wiring?
A: The documented wiring specification calls for shielded copper conductors. Shielded wiring assists in reducing noise coupling into low-level analog signal circuits.

Q: Is the 1715-TAS0F8I interchangeable with termination assemblies for other 1715 analog output modules?
A: The assembly is specified for use with the 1715-OF8I isolated analog output module. Compatibility with other modules should be verified against the applicable Rockwell Automation documentation.

Field Installation Guidelines

• Install the termination assembly inside a grounded industrial enclosure suitable for the operating environment.

• Verify that the connected module is a 1715-OF8I before applying field wiring.

• Use shielded copper conductors rated for at least 85 deg C.

• Route analog output cables separately from motor feeders, contactor wiring, and other high-energy conductors.

• Terminate cable shields according to the site grounding philosophy to avoid unintended ground-loop currents.

• Inspect all channel fuses prior to commissioning and replace only with equivalent specified ratings.

• Apply the recommended terminal torque to prevent conductor loosening and terminal damage.

• Confirm field supply voltage remains within the specified 18-32 VDC operating range before energization.
