Yokogawa AAI135-S00 8-Channel Isolated 4-20 mA Analog Input Module for CENTUM VP

Accurate analog signal acquisition is the foundation of reliable industrial process control. In modern DCS applications, stable input signals from transmitters directly influence process monitoring, control accuracy, and plant safety. The Yokogawa AAI135-S00 is an 8-channel isolated 4–20 mA Analog Input Module designed for CENTUM VP, CENTUM CS 3000, and FIO (Field Control I/O) systems. Individual channel isolation helps reduce electrical interference between field devices, improving measurement stability and supporting continuous operation in demanding industrial environments.

The AAI135-S00 is commonly used in continuous process industries where accurate analog signal acquisition is essential for stable plant operation. Its primary function is to receive 4–20 mA signals from field transmitters while isolating each input channel to reduce electrical interference. This design helps improve measurement reliability, maintain control accuracy, and support long-term operation of Yokogawa DCS systems.
