Product Description
The SAI533-H33 S1 is a precision analog output module for the Yokogawa CENTUM VP. It converts digital control signals into 4–20 mA DC outputs, enabling accurate control of actuators, valves, positioners, and variable frequency drives.
With 16-bit D/A conversion and galvanic isolation, the module ensures stable, high-fidelity outputs, minimizing loop variance and signal drift in critical process control loops.

FAQ
Can it be used for voltage-based control?
No. The module is designed for current-loop (4–20 mA) applications. Voltage-only devices require an external converter or proper shunt resistor.
Is the S1 revision compatible with standard terminal boards?
Yes. It supports plug-and-play installation with CENTUM VP terminal boards for easy integration and maintenance.
