The Yokogawa SDV541 is a 16-channel digital output module designed for Yokogawa ProSafe-RS Safety Instrumented Systems (SIS) and compatible CENTUM CS / CENTUM VP architectures.
It is used to transmit 24 V DC ON/OFF control signals to field devices such as relays, solenoid valves, alarms, and actuators. Compared to the smaller SDV531 (8-channel), the SDV541 provides higher channel density (16 outputs), making it ideal for large-scale safety and control systems.
Engineered for mission-critical environments, the SDV541 ensures high reliability, strong electrical isolation, and stable operation under harsh industrial conditions.
