Product Description

The AAI835-S00 S2 is a hybrid analog I/O module designed for the Yokogawa CENTUM VP and CS 3000 distributed control systems. It integrates four analog input channels and four analog output channels in a single compact module, all operating on 4–20 mA current signals with full channel-to-channel and channel-to-system isolation.

As a Style S2 hardware revision, this module incorporates updated internal components to improve thermal performance and long-term reliability while remaining fully compatible with existing system infrastructure. The AAI835-S00 S2 is optimized for accurate signal acquisition and precise control of final elements such as control valves, VFDs, and actuators.

Technical Specifications

Application

The AAI835-S00 S2 is well suited for space-constrained control environments, including:

• Skid-mounted process units

• Remote or localized I/O stations

• Compact reactor and pressure-control systems

By combining input and output functions on a single card, it reduces rack usage while maintaining reliable closed-loop control.

Frequently Asked Questions

Does the AAI835-S00 S2 support HART communication?
No. The S00 variant is a standard analog type without HART support. For HART-enabled applications, the H50 series should be selected.

What is the difference between S2 and earlier S1 versions?
The S2 style denotes a hardware update focused on improved component durability and thermal stability, while remaining fully backward compatible with existing baseplates and system configurations.
