Product Description
The Yokogawa SDV531-S13 is a high-reliability, 8-channel digital output module for the ProSafe-RS Safety Instrumented System (SIS). Operating as a 24 V DC current-sourcing output, it is designed to drive field devices such as solenoid valves, relays, and industrial indicators in safety-critical applications.
With robust module isolation and high current handling capability, the SDV531-S13 protects system logic from external electrical disturbances while ensuring deterministic output behavior during safety demands. Supporting a total module output capacity of 4.8 A and fast response times, it is well suited for Emergency Shutdown (ESD) and Fire & Gas (F&G) systems in harsh industrial environments.

Technical FAQ
Q: What does the -S13 suffix indicate?
A: The -S13 suffix defines a specific functional safety hardware revision, fully compatible with standard ProSafe-RS FIO safety nests.
Q: Does the SDV531-S13 support load monitoring?
A: Yes. The module includes internal diagnostics to supervise output circuit health and confirm load controllability during safety demands.
Q: Is this module suitable for high-speed switching applications?
A: No. With a 30 ms response time, it is optimized for safety shutdown and actuation, not for high-frequency or PWM switching.
