Yokogawa SDV144-S13 Style S1 Digital Input Module

Description:

The Yokogawa SDV144-S13 (Style S1) Digital Input Module is used a 16-channel discrete input module used in Yokogawa CENTUM VP and ProSafe-RS systems. It receives no-voltage (dry contact) signals from field devices such as switches, relays, and sensors, converting them into digital signals for the control system. The module is designed for high-reliability industrial environments and supports system redundancy.

Applications:

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