Yokogawa AAI143-H53/K4A00 Analog Input Module

Product Description

AAI143-H53/K4A00 is a 16-channel isolated analog input module of Yokogawa FIO series for CENTUM VP / CENTUM CS DCS system, supporting HART protocol. Suffix H means HART communication enabled; 5 stands for non-explosion-proof; 3 indicates ISA G3 anti-corrosion grade and operating temperature range -20~70℃. /K4A00 includes KS cable interface adapter ATK4A-00 for connecting AEA4D terminal board. Each channel is individually isolated to acquire 4-20mA field signals and read diagnostic data from HART smart transmitters. It features strong noise immunity for DCS applications in chemical, power and other industrial plants.
