Honeywell 51400700-100 | DHI Module for LCN Network Integration

Product Description / Overview

The Honeywell 51400700-100 DHI is a Data Hiway Interface (DHI) card designed for Honeywell TDC 3000 and Experion PKS distributed control systems.
It enables seamless communication between the Local Control Network (LCN) and the Data Hiway, converting signals, buffering data, and sequencing messages efficiently.
Moreover, this module supports high-speed, deterministic communication, ensuring reliable data exchange across controllers, operator stations, and gateways.
In addition, its industrial-grade PCB design provides robust performance under continuous operation in demanding process environments.
The 51400700-100 is essential for linking high-speed LCN modules with widely dispersed, slower Data Hiway devices.
