Honeywell 4DP7APXDH111 | Data Hiway Interface Module
Product Description
The Honeywell 4DP7APXDH111 is a Data Hiway Interface (DHI) module designed for TDC 3000 distributed control systems. It functions as a communication bridge between Honeywell Multifunction Controllers (MCs), Process Interface Units (PIUs), and the Data Hiway network. This module converts parallel TTL signals from controllers into serial data, enabling efficient transmission over 75-ohm coaxial cable.
Built with redundant circuitry and dual coaxial connectors, the 4DP7APXDH111 supports Hiway A and B redundancy, ensuring uninterrupted data communication. It uses Direct Memory Access (DMA) for fast data transfer and responds only to properly addressed command and data words, maintaining system integrity in industrial environments.
