Description
Overview
The Yokogawa AAI835-H50/K4A00 is a 4-channel analog input/output module designed for use in CENTUM VP and CS 3000 distributed control systems. It supports 4–20 mA current signals for both input and output. Each channel is isolated to ensure high accuracy and noise immunity. The H50 suffix adds HART communication support, while the K4A00 option includes a KS cable interface adapter for simplified connection to terminal boards like AEA4D.
