Product Overview
The Yokogawa AAI543-S50/A4S10 is a 16-channel isolated analog output module designed for precise 4–20 mA current signal transmission in industrial control systems. It supports standard switch-over in redundant configurations, ensuring continuous operation and minimal process disturbance during module switchover. Equipped with HART communication capability, it allows both analog signal output and digital parameter exchange with smart field devices. Its high isolation rating between output and system ensures safety and signal integrity in demanding environments.
