The Yokogawa AAV144-S00 is a specialized 16-channel analog input module designed for use in Yokogawa Distributed Control Systems (DCS). It efficiently interfaces with field instruments, such as pressure transmitters, temperature sensors, and flow meters, to acquire and convert analog signals into a digital format for processing by the control system. The module features isolated channels and is ideal for applications requiring high-accuracy signal conversion with fast data update capabilities.
