Product Description
The AAI135 S3 is a high-precision 8-channel analog input module designed for Yokogawa Centum VP and CS 3000 Distributed Control Systems (DCS). It is optimized for capturing 4 to 20 mA signals from field transmitters while maintaining full channel isolation to protect against common-mode noise and ensure maximum signal integrity.
The S3 Style Code denotes a hardware revision with updated internal components, improved thermal performance, and enhanced reliability, while remaining backward compatible with earlier AAI135 modules. Its compact FIO form factor enables high-density installation in control cabinets, making it ideal for space-constrained applications.

Frequently Asked Questions
Q: Can the AAI135 S3 be used in a redundant configuration?
A: Yes. It supports dual-redundancy when installed on a compatible FIO baseplate, allowing hot-swappable maintenance without interrupting the process.
Q: Is this module compatible with HART-capable transmitters?
A: The module can process the 4–20 mA analog signal from a HART transmitter but does not support digital HART communication. For HART transparency, the AAI135-H variant should be used.
