Product Details
Product Overview
The Yokogawa AAR181-S00 S2 is a high-density 16-point RTD Input Module engineered for the Field Integrated Operation (FIO) platform. It provides precision temperature data acquisition by interfacing directly with Resistance Temperature Detectors (RTDs), including the industry-standard Pt100. This module integrates seamlessly into CENTUM VP and CENTUM CS 3000 distributed control systems, offering robust signal isolation and built-in HART communication capabilities. Its primary role involves converting analog resistance values into digital data for critical process monitoring in power generation, chemical refining, and large-scale manufacturing.

Engineering Advantages
-
Superior Signal Integrity: Full channel-to-channel isolation eliminates ground loops and prevents electrical noise from one sensor affecting the readings of the other 15 channels. This ensures laboratory-grade accuracy in high-EMI industrial environments.
-
HART Digital Integration: The module supports the HART protocol, allowing engineers to perform remote configuration and retrieve device-specific diagnostics without visiting the field instrument. This feature significantly reduces maintenance hours and improves asset management.
-
High-Density Installation: Packing 16 isolated channels into a compact 300g module maximizes rack space efficiency. This high-density design allows for extensive temperature monitoring grids within a small hardware footprint.
-
Extreme Environment Resilience: Yokogawa coats the internal circuitry to resist corrosion and humidity. The ruggedized S2 style hardware maintains calibration stability even when subjected to the thermal cycling found in heavy industrial cabinets.
-
Flexible Wiring Support: The AAR181-S00 S2 accommodates multiple RTD wiring schemes, providing the flexibility to use existing field cabling while maintaining precise lead-wire resistance compensation.
FAQs
Q1: Can the AAR181-S00 S2 handle both Pt100 and Ni100 sensors simultaneously?
A1: Yes. The module supports multiple standard RTD types. You configure each channel via the CENTUM software to match the specific sensor type installed in the field.
Q2: Does this module require an external power supply for the RTDs?
A2: No. The AAR181-S00 S2 provides the necessary excitation current for the RTD sensors directly from the FIO bus, simplifying your cabinet power distribution.
Q3: Is the style "S2" compatible with older AAR181-S00 racks?
A3: Yes. The "S2" style code represents a hardware refinement that remains backward compatible with the standard AAR181-S00 footprint and software environment.
Q4: Is this a brand new unit or a refurbished spare?
A4: We supply the AAR181-S00 S2 as a 100% brand new, original Yokogawa factory part in its original packaging, complete with a full 12-month industrial warranty.
