Product Description
Overview
The Yokogawa AAI135-H53 is a high-precision analog I/O module designed for integration with ESB bus node units (ANB10S, ANB10D), optical ESB bus units (ANB11S, ANB11D), and field control units (AFV30S, AFV30D, AFV40S, AFV40D, AFV10S, AFV10D). This module converts field analog signals into digital data for field control stations (FCS) and translates FCS data into analog signals for output devices, ensuring seamless process control.
