Product Description
The SDV541-S33-S2 is a high-integrity safety digital output module designed for the Yokogawa ProSafe-RS Safety Instrumented System (SIS). It provides 16 isolated 24 V DC output channels to drive critical final control elements such as solenoid valves, actuators, and audible alarms.
Certified for SIL3 applications, the SDV541-S33-S2 features a safety-first hardware architecture to ensure reliable transition of process equipment to a safe state during emergency events. The S2 revision represents an optimized hardware build with enhanced thermal stability and long-term reliability, ideal for continuous-process industrial applications.
Manufactured in Singapore, the module incorporates advanced diagnostics, including pulse testing to verify output circuit integrity and field wiring fault detection (short circuits or open loops) without disrupting the energized load.

Industrial Application
The SDV541-S33-S2 is commonly used in high-risk industrial sectors, including:
-
Chemical refineries
-
LNG terminals
-
Offshore platforms
It is typically deployed in Emergency Shutdown (ESD) and Fire & Gas (F&G) systems, supporting de-energize-to-trip logic and ensuring reliable fail-safe operation of final control elements.
High-Current Load Handling
Each output channel can supply up to 0.6 A, with a total module supply rating of 3.4 A. This allows simultaneous actuation of multiple high-demand solenoids. For applications exceeding these limits, interposing relays are recommended to protect the module’s safety circuitry.
