Yokogawa AAR181-S50 TC/RTD Input | 100% Original Japan

Yokogawa AAR181-S50 TC/RTD Input | 100% Original JapanProduct Overview The Yokogawa AAR181 S50 (Style S2) functions as a high density, 16 channel isolated temperature input module for the CENTUM VP and ProSafe RS Distributed Control Systems. This module captures precise low level signals from Resistance Temperature Detectors (RTDs) and Thermocouples (TC), converting them into high fidelity digital data. As a critical component of the Field I O (FIO) family, the AAR181 S50 provides the robust isolation

By utilizing a high-density shielded design

By providing a secure galvanic barrier between field-side voltage (up to 250V AC/DC) and the sensitive control logic of the C300 controller

The 4 analog outputs are powerful enough to drive standard Woodward proportional actuators directly

This design ensures that a single component failure on one board does not cause a turbine trip

System Architecture: Triple Modular Redundant (TMR)

What does "Sourcing" mean for this module

meeting the rigorous demands of offshore oil platforms and chemical refineries

It is famously associated with systems that operated unmanned for over 25 years in harsh industrial environments

55 W maximum Number of Outputs 16 channels Output Type Sourcing (PNP) Operating Voltage Range 20

Thermal Management: Maintain at least 50 mm of clearance above and below the power supply module to facilitate natural convection cooling

high-speed communication with the plant’s supervisory network

it can trigger automated protective actions to shut down the compressor if pressure limits exceed safety thresholds
