Product Description
The AAR181-S50 S2 is a high-precision 16-channel analog input module designed for the Yokogawa CENTUM VP and ProSafe-RS systems. It supports both thermocouples (TC) and resistance temperature detectors (RTD), providing accurate temperature data directly to the control logic.
This module integrates cold junction compensation and linearized temperature conversion, eliminating the need for external signal converters. The S2 hardware revision enhances circuit stability and reduces power consumption, while the module’s isolated input design protects the system from field-side electrical noise. Manufactured in Japan, it fits seamlessly into Yokogawa I/O units for modular deployment.
