Product Description

The AAI141-S00/A4S00 is a 16-channel high-density analog input module designed for Yokogawa CENTUM VP and CS 3000 DCS environments. It converts standard field signals, such as 4–20 mA current or 1–5 V voltage, into digital data for precise process monitoring. The S00 designation indicates a standard hardware build, while the /A4S00 option provides a factory-installed ATA4S-00 Pressure Clamp Terminal Block, enabling direct and secure field wiring.

Unlike the AAI143 series, which provides loop power to 2-wire transmitters, the AAI141-S00/A4S00 is typically used with externally powered transmitters or for voltage signal acquisition. With a 100 Hz sampling rate and a high-speed 10 ms scan cycle, it delivers accurate, real-time process data for demanding industrial applications.

Technical Specifications

Module Application and Reliability

• Deployment: Centralized control rooms or localized I/O cabinets.

• Applications: High-speed acquisition of pressure, temperature, and flow signals.

• Integration: Compatible with FIO nodes for new installations or system expansions.

• Design: Rack-mounted, optimized for high-fidelity signal acquisition in industrial environments.

Frequently Asked Questions

Q: Are the channels isolated?
A: No. Channels are non-isolated. For per-channel galvanic isolation, consider the AAI143 or AAI135 series.

Q: Can this module be used in redundant configurations?
A: Yes. It supports dual-redundancy when installed on a compatible FIO baseplate, ensuring continuous signal processing if one module fails.
