Product Description

The AAV141-S00 is a 16-channel 1–5 V DC analog input module designed for Yokogawa’s FIO (Field network I/O) architecture, compatible with CENTUM VP and CENTUM CS 3000 systems. As a Basic Type module, it is optimized for high-speed data acquisition in non-isolated applications, offering a cost-effective solution for high-density voltage signal monitoring where channel-to-channel isolation is not required.

With a 40 ms data update cycle, the module provides real-time digital conversion of field signals for process control. Its high-precision design (±0.1% accuracy) and thermal stability make it suitable for applications where field devices are already isolated or share a common grounding scheme.

Technical Specifications

Industrial Applications

The AAV141-S00 is commonly used in:

• Chemical and pharmaceutical plants

• Water treatment facilities

• Analytical instrument and secondary transmitter monitoring

It is ideal for non-critical auxiliary systems where high-density voltage signal monitoring is needed without the extra cost or space for isolation.

Frequently Asked Questions

How does the non-isolated design affect installation?

• All 16 channels share a common negative ground internally. Ensure that connected field devices are either already isolated or share the same ground potential to avoid measurement errors.

Can the module measure 4–20 mA signals?

• Yes, by using 250 Ω precision shunt resistors at the terminal board to convert 4–20 mA currents into a 1–5 V signal compatible with this module.
