Honeywell 51108088100 Product Description

Model: 51108088100 (Standard Model: 51108088-100)

Brand: Honeywell

Series: TDC 3000 / Experion PKS System

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

I. Product Overview

51108088-100 is the core I/O signal transfer and interface management module of Honeywell TDC 3000 distributed control system. As the physical interface hub between the controller (CPU) and the field I/O rack and signal cables, it is responsible for signal transfer, electrical isolation, port mapping, and fault diagnosis, achieving 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.
