Product Details
Product Description
The AAI143-H50 / K4A00 analog input module from Yokogawa is designed for distributed control systems requiring precise current signal acquisition. This model provides 16 isolated input channels for 4–20 mA DC signals, ensuring reliable measurement and integration with smart field devices. The H50 suffix indicates HART communication support, no explosion protection, and basic hardware type. The K4A00 option adds compatibility with the KS cable interface adapter (Model: ATK4A-00), enabling connection to the AEA4D terminal board.
