Honeywell 51109701100 Product Description

Model: 51109701100 (Standard Model: 51109701-100)

Brand: Honeywell

Series: TDC 3000 / TPS Control System

Type: Floppy Disk Drive Module 

I. Product Overview

51109701-100 is a dedicated built-in floppy disk drive for Honeywell TDC 3000 distributed control system, mainly used in Universal Station (US), GUS operation stations and engineer stations. It is the core external storage device for loading programs, configuring backups, upgrading software, and exporting/importing data in the system. As the standard data interface for old DCS systems, it ensures offline configuration, fault recovery, and program distribution in a network-free environment. It is the key hardware for TDC 3000 system maintenance and configuration.
