Yokogawa Electric Corporation SDV521-S63-S3 Digital Output Module

The Yokogawa SDV521-S63-S3 is a 16-channel digital output module for Yokogawa CENTUM VP and ProSafe-RS systems that delivers discrete ON/OFF control signals from the controller to field devices. Each channel features a 24 VDC transistor/contact output with about 0.2 A per channel, powered from an external 24 VDC supply (+20%/−10%), and the module provides isolation between channels and the system bus with a typical response time of 30–40 ms. Designed for high-reliability industrial environments and safety-critical applications, it supports isolated channels and redundant configurations, and it is commonly used to control valves, relays, solenoids, alarms, motors, and interlock systems in oil and gas, LNG plants, chemical processing, and power generation; interface is a signal cable interface with suffix '6', and operating temperature ranges from -20 to 70 °C.
