Overview
The Yokogawa AST143-S00 is a TC/mV input module designed for precise thermal monitoring and millivolt signal acquisition in demanding industrial environments. It supports up to 16 isolated input channels, each capable of handling thermocouple (TC) or millivolt (mV) signals, making it ideal for applications requiring high signal integrity and fast response times.
Built for safe operation in hazardous areas such as Zone 2/Division 2, the module offers 1500 V AC isolation, ensuring protection against electrical interference and transient faults. Its compact form factor and compatibility with Yokogawa’s DCS systems allow for easy integration into existing control architectures. Additionally, the AST143-S00 offers low signal drift and high-speed data updates, making it ideal for real-time process control.
This module is widely used in industries like chemical processing, power generation, oil & gas, and pharmaceuticals, where precise temperature and voltage measurements are essential for operational safety and efficiency.
