The Yokogawa SAV144 is a 16-channel isolated analog input module used in Yokogawa ProSafe-RS Safety Instrumented Systems (SIS) and related CENTUM / safety node architectures.
It is designed to acquire voltage-based process signals (1–5 V / 1–10 V) from field instruments such as transmitters, pressure sensors, and monitoring devices. The module ensures high-precision signal conversion with strong electrical isolation, making it suitable for safety-critical and high-integrity automation systems.
SAV144 is widely deployed in ESD, F&G, BMS, and HIPPS applications, where stable analog signal acquisition is essential for plant safety and control reliability.
