Product Description
Product Details: Yokogawa AAT145-S50 S1 - TC/RTD Input Module (16-channel, Isolated Channels)
The Yokogawa AAT145-S50 S1 TC/RTD Input Module is a high-performance solution designed for industrial automation systems. It supports a variety of input signal types, including thermocouple (TC), resistance temperature detectors (RTD), millivolt (mV), and potentiometer (POT) signals. This module features 16 isolated channels, providing high signal isolation between the field and the system, as well as between each channel. It is designed for use in dual-redundant configurations to ensure continuous operation in critical systems.
