Overview
The Yokogawa SAV144-S33 Analog Input Module is engineered for precise voltage signal acquisition in safety-critical and SIL-rated environments. It features 16 individually isolated input channels, capable of handling 1–5 V or 1–10 V signals, with an extended tolerance up to ±30 V. This flexibility makes it ideal for monitoring a wide range of field instruments such as pressure transmitters, flow sensors, and level indicators.
The module offers high input impedance (1 MΩ when powered, 100 kΩ when unpowered), ensuring minimal signal loading and accurate readings. Its robust electrical isolation and resistance to environmental interference make it suitable for deployment in harsh industrial conditions, including oil & gas, chemical processing, and power generation.
The SAV144-S33 integrates seamlessly with Yokogawa’s ProSafe-RS safety system, supporting SIL-rated applications and contributing to overall system integrity and regulatory compliance.

Typical Applications
-
Safety Instrumented Systems (SIS): Monitors analog signals from field devices in emergency shutdown and fire/gas systems.
-
Process Control in Refineries: Tracks pressure, temperature, and flow signals in hazardous zones.
-
Chemical Manufacturing: Ensures accurate analog input for dosing, mixing, and reaction control.
-
Power Generation: Interfaces with sensors for turbine and boiler monitoring.
-
OEM Safety Panels: Integrated into custom-built control cabinets requiring high-integrity analog input.
For example, in a chemical plant’s SIS, the SAV144-S33 can monitor pressure transmitters and trigger alarms or shutdowns if thresholds are exceeded. Therefore, it plays a critical role in operational safety and regulatory compliance.
