The Yokogawa AAI835-H50 is an analog input/output (I/O) module designed for industrial process control applications.

It acts as a bridge between field devices and a control system, handling both analog input and output signals.

• Functionality:

  • Analog Input: Takes analog signals (typically 4-20 mA DC current loop) from up to 4 field devices like pressure transmitters, temperature sensors, or flow meters. It converts these signals into digital signals for the control system to understand.
  • Analog Output: Conversely, it can also receive digital signals from the control system and convert them back into analog signals (typically 4-20 mA DC current loop) to control field devices like valves, actuators, or variable speed drives.
