Products Description
The Honeywell TC-FTEB01 (part number 51309512-125) is a fault-tolerant Ethernet (FTE) bridge module designed specifically for industrial control applications. Its core function is to provide highly reliable connections between nodes in the Honeywell Experion PKS distributed control system (DCS) and the FTE network. As a key component of the FTE network architecture, it ensures uninterrupted real-time data exchange between the control layer and field devices through redundant communication path design, while also being compatible with the Experion LS I/O module series and third-party Ethernet devices. The module features a compact, industrial-grade design, enabling stable operation in harsh environments such as extreme temperatures and high electromagnetic interference. It is suitable for building networks for new DCS systems and can also serve as an upgrade spare part for existing systems, providing critical network support for continuous production in process industries.
