Overview

The Yokogawa AAI543-S00/A4S00 is a robust 16-channel isolated current output module designed for industrial automation systems. It features a standard switch-over response in redundant configuration without explosion protection, along with the ISA Standard G3 option and a KS Cable Interface Adapter (For connecting AEA4D Terminal Board). This module provides a reliable solution for applications requiring accurate 4 to 20 mA output signals in harsh environments.
