Introduction

The Yokogawa SAV144-S33 Analog Input Module is a high-reliability 16-channel voltage input module designed for ProSafe-RS safety instrumented systems (SIS) and CENTUM VP distributed control architectures. It is engineered to acquire precise analog voltage signals from field instruments and convert them into stable digital data for real-time process monitoring and safety logic execution.

With strong electrical isolation and SIL-oriented design principles, the SAV144-S33 is widely used in mission-critical industrial environments where measurement accuracy and system integrity directly impact plant safety and uptime.
