Yokogawa AAR181-S50 S2 RTD Iuput Module

Product Introduction

The Yokogawa AAR181-S50 S2 RTD Input Module is a high-precision input module designed for Yokogawa’s distributed control systems (DCS). It is engineered to measure resistance temperature detectors (RTDs) and convert these resistance values into standardized digital signals for accurate process monitoring and control.

The module supports a variety of RTD sensor types, including Pt100 and Pt1000, and provides reliable temperature measurement in industrial environments. Its advanced signal conditioning, high linearity, and noise immunity make it ideal for processes where precise temperature monitoring is critical. The AAR181-S50 S2 is optimized for seamless integration into Yokogawa control systems, ensuring real-time data acquisition, diagnostics, and fault detection.
