The Yokogawa SDV541-S23 is a 16-channel digital output module used in Yokogawa ProSafe-RS Safety Instrumented Systems (SIS) and compatible CENTUM CS / CENTUM VP DCS systems.
It provides 24 V DC ON/OFF control signals to field devices such as solenoid valves, relays, alarms, and actuators. The module is designed for high-reliability safety applications including ESD, F&G, BMS, and HIPPS systems, where stable output switching is critical.
The suffix “-S23” defines a configuration variant typically indicating:
- S = Standard type
- 2 = MIL cable / pressure clamp terminal option
- 3 = ISA G3 environmental rating (-20°C to +70°C)
