The Yokogawa SAV144-S63 is a 16-channel isolated analog input module designed for Yokogawa ProSafe-RS Safety Instrumented Systems (SIS) and related DCS safety architectures.
It is used to acquire high-precision voltage signals (1–5 V / 1–10 V) from field instruments such as transmitters, pressure sensors, and monitoring devices. The module provides strong electrical isolation and fast signal processing, making it suitable for critical safety applications including ESD, F&G, BMS, and HIPPS systems.
The “-S63” suffix typically indicates a configuration with signal cable interface adapter support and ISA G3 environmental compliance (-20°C to +70°C), making it suitable for harsh industrial environments.
