Product Overview
The TK-FTEB01 (Part Numbers: 51309512-175 / 51403483-100) is a specialized Fault Tolerant Ethernet (FTE) bridge module designed for Honeywell Experion LS and PKS platforms. It serves as a critical communication link between the controller chassis and the FTE network, providing redundant, high-speed data paths for I/O modules and controllers. Unlike standard Ethernet cards, this module is engineered for industrial resilience, ensuring uninterrupted communication even in the event of a single cable or switch failure.

Built for high-density industrial environments, the TK-FTEB01 facilitates deterministic data exchange and provides network diagnostics via the Experion software. Its compact form factor allows easy integration into Series-A chassis, supporting the stringent reliability requirements of Distributed Control Systems (DCS) in chemical, pharmaceutical, and energy industries.

Frequently Asked Questions (FAQ)

Q: What is the significance of “Fault Tolerant” in this module?
A: The TK-FTEB01 provides multiple communication paths using Honeywell’s FTE technology. If one network cable fails, the module instantly reroutes data through the alternate path without losing control or visibility.

Q: Does this module support standard RJ45 connectors?
A: Yes, it uses standard industrial Ethernet cabling and RJ45 connectors, but full redundancy requires an FTE-compliant network architecture.
