Product Overview

The Yokogawa AAR181-S00-S2 is a high-precision RTD input module designed to provide accurate temperature monitoring in critical industrial applications. Integrated within the Yokogawa Field Integrated Operation (FIO) system, this module efficiently handles Resistance Temperature Detector (RTD) signals, particularly Pt100 (3-wire) sensors, ensuring the integrity of your temperature measurements.

The AAR181-S00-S2 module is designed with channel-to-channel and channel-to-system isolation, minimizing noise and improving signal fidelity. With its low measurement current of 1 mA, it minimizes self-heating errors in RTD sensors, providing accurate readings for demanding process control applications. Furthermore, the compact design allows for easy integration into CENTUM VP and CENTUM CS systems, ensuring optimal performance in a wide range of industrial environments.
