Honeywell 51108899100 Product Description

Model: 51108899100 (Standard Model: 51108899-100)

Brand: Honeywell

Series: TDC 3000 / TPS / Experion PKS Control System

Type: I/O Interface Adapter Board (Paddle Board) 

I. Product Overview

51108899-100 is an advanced I/O signal conversion and interface management module of Honeywell TDC 3000 distributed control system. As the core physical interface hub between the controller (K2LCN, HPK2) and the field I/O rack and signal cables, it is responsible for high-speed signal conversion, electrical isolation, port mapping, fault diagnosis, communication protocol conversion, and realizes reliable signal interconnection between the control system and field instruments and actuators. It is the key transfer unit of the I/O link in the DCS system.
