Product Description
The Yokogawa SAI143-H33/PRP is a high-performance 16-channel analog input module designed for the CENTUM VP distributed control system. It is optimized for precise acquisition of 4–20 mA current loop signals from field transmitters, forming a reliable data interface between process instrumentation and control logic.
The module incorporates individual channel isolation and built-in diagnostics to maintain signal accuracy and system availability in electrically noisy industrial environments. Although sometimes referenced alongside power-related terminology, the SAI143-H33/PRP is not a power supply module; it draws operating power from the system backplane and is dedicated exclusively to analog signal acquisition.

It is commonly used for monitoring pressure, flow, and level transmitters that rely on standard 4–20 mA signaling within CENTUM VP architectures.
FAQ
Q: Does the SAI143-H33/PRP support HART communication?
The SAI143 series is designed for standard analog input. Certain “H” variants (such as H33) are used in installations involving digital signal overlays, but HART capability depends on firmware and system configuration and should be verified against Yokogawa documentation.
Q: Can the SAI143-H33/PRP be hot-swapped during operation?
Yes. When installed in a redundant N-IO or FIO node, the module can be replaced without interrupting active control loops.
