Product Description
Product Overview
The Yokogawa AAR145-S50 S1 is an RTD/POT Input Module designed for precise signal acquisition in industrial control systems. Part of the TC/RTD Input Modules series, this 16-channel module accepts signals from resistance temperature detectors (RTD) and potentiometers (POT), with isolation between the field and system as well as between each channel. Suitable for dual-redundant configurations, it offers robust performance for temperature and position monitoring applications.
