Yokogawa SDV144-S13 Style S4 Digital Input Module

Description:

The Yokogawa SDV144-S13 (Style S4) Digital Input Module is used a 16-channel input module used in Yokogawa CENTUM VP and ProSafe-RS systems. It receives discrete (ON/OFF) signals from field devices such as switches, relays, and sensors, converting them into digital data for the control system. The module is designed with channel isolation and supports high-reliability industrial operation, including redundant configurations.

Applications:

The Yokogawa SDV144-S13 is used in industrial automation systems to monitor digital signals from field equipment. It is commonly deployed in oil & gas, LNG plants, chemical processing, and power generation. The module enables real-time monitoring of equipment status such as valve positions, alarms, limit switches, and interlocks, ensuring safe and stable process operation.
