Product Description
Product Overview
The Yokogawa AAI141-S50/A4S00 is an Analog Input Module designed to handle 16 non-isolated inputs, primarily for 4 to 20 mA DC signals from 2-wire or 4-wire transmitters. It supports dual-redundant configuration and includes a pressure clamp terminal block, making it a reliable choice for industrial control systems.
