Product Introduction – Yokogawa AIP502
The Yokogawa AIP502 is a high-performance Analog Input Module designed for integration within the Yokogawa CENTUM VP Distributed Control System (DCS). Developed to deliver accurate, stable, and reliable analog signal acquisition, the AIP502 supports multiple input signal types and offers robust isolation features, making it ideal for use in critical process control environments such as oil and gas, petrochemical, power generation, and pharmaceutical industries.
This module is engineered with high-density channel configuration, enhanced diagnostics, and plug-and-play compatibility with Yokogawa’s Vnet/IP architecture. It plays a pivotal role in converting field analog signals (such as 4-20 mA) into digital data for use within process control strategies.
