Technical Overview

The AAV141-S00 (S2) is a high-density analog input module designed for the Yokogawa Electric Corporation CENTUM VP Distributed Control System (DCS).

Operating within the FIO (Field I/O) subsystem, this module interfaces directly with voltage-output field instruments. It provides 16 input channels, isolated in groups, ensuring accurate and stable acquisition of critical process variables.

Optimized for high-speed processing and strong noise immunity, the AAV141-S00 is well-suited for electrically demanding industrial environments where signal integrity and system protection are essential.

Detailed Technical Specifications

Industrial Applications

Pressure & Level Monitoring
Interfaces with voltage-output transmitters installed across local or remote I/O nodes.

Environmental & Safety Monitoring
Acquires multi-point voltage signals from temperature, gas concentration, or environmental sensors.

Turbine & Machinery Control
Captures high-speed voltage-based vibration or position signals for rotating equipment monitoring and protection systems.

Technical FAQ

What does the S2 suffix indicate?
The S2 suffix denotes a specific hardware revision or style code, ensuring compatibility with newer CENTUM VP cabinet designs and terminal boards while maintaining core module functionality.

How is signal isolation implemented?
The module incorporates galvanic isolation between the field wiring and the internal system bus, preventing ground loops and protecting the controller from field-originated voltage surges.

Can this module process 4–20 mA current signals?
The AAV141-S00 is a voltage input module. To accept 4–20 mA signals, a precision 250 Ω shunt resistor must be installed at the terminal block to convert the current signal into a 1–5 V DC input.
