The Yokogawa AA1141-S00/S2 is an analog input/output (I/O) module designed for industrial process control applications within Yokogawa’s CENTUM VP systems.

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

Here’s a breakdown of its functionalities:

• Analog Input/Output:
  • Input: Takes analog signals (typically 4-20 mA DC current loop) from up to 8 field devices like pressure transmitters, temperature sensors, or flow meters. It converts these signals into digital signals for the control system to understand.
  • 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.
