Product Description
The AAI841-H00 S2 is a high-performance analog input module for the Yokogawa CENTUM VP Distributed Control System (DCS). Although sometimes misidentified as a motor-related component due to its industrial form factor, this unit is strictly a signal acquisition and processing module used to interface field transmitters with the control system.
The module provides 16 channels of 4–20 mA analog current input, making it well-suited for precise and reliable process variable measurement. Designed for high-availability systems, it offers robust environmental resistance and supports redundant system architectures. Field wiring is accomplished via pressure clamp terminals or dedicated signal cables, depending on the installed baseplate.

Frequently Asked Questions
Q: Is the AAI841-H00 S2 compatible with HART communication?
A: No. This is a standard analog input module. For HART-enabled applications, models such as AAI841-H80 should be selected.
Q: What does the “S2” suffix indicate?
A: The S2 suffix represents a specific hardware revision (Style Code), indicating updated internal components or manufacturing standards while maintaining backward functional compatibility.
