Overview

The Yokogawa AAI543-S03/A4S00 is a 16-channel isolated current output module designed for industrial applications. It features a standard switch-over response in a redundant configuration without explosion protection, with options including ISA Standard G3 and a temperature range of -20 to 70 °C. It is compatible with the KS Cable Interface Adapter for connecting the AEA4D Terminal Board.
