Product Description
The AAI835-H00-S2 is a hybrid analog I/O module designed for the Yokogawa CENTUM VP distributed control system. This Style S2 (hardware revision) module integrates four analog input channels and four analog output channels, all operating on 4–20 mA current signals, making it ideal for compact control applications where sensing and actuation are closely coupled.
The module supports HART digital communication, enabling transparent pass-through of diagnostics and multivariable data from smart field instruments to the control system. Full channel-to-channel and channel-to-system isolation protects system logic from surges, noise, and common-mode interference, ensuring stable operation in demanding industrial environments.

Application
The AAI835-H00-S2 is commonly used in space-constrained and modular control systems, including:
-
Chemical dosing and blending skids
-
Small-scale turbine and auxiliary systems
-
Oil & gas separator and package units
By combining transmitter inputs and final control outputs on a single module, it reduces rack usage and simplifies spare parts management.
Frequently Asked Questions
What is the advantage of the S2 designation?
The S2 (Style 2) indicates a hardware lifecycle update with improved internal components and thermal performance, while remaining fully compatible with standard CENTUM VP I/O baseplates.
Does the AAI835-H00-S2 support redundancy?
Yes. When installed on a redundant-capable baseplate, the module can be deployed in redundant pairs to support high-availability control loops.
