Product Description
The AAV141 is a 16-channel voltage input module designed for Yokogawa’s FIO (Field network I/O) system, compatible with CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). It is engineered for high-fidelity measurement of DC voltage signals (typically -10 V to +10 V), providing fast and precise data acquisition for critical process control.
The module delivers robust electrical isolation between field signals and system logic, protecting against ground loops and external surges. Its high-density, 16-channel design allows efficient use of cabinet space, while support for dual-redundant configurations ensures maximum system availability for mission-critical operations.

Industrial Applications
The AAV141 is widely used in:
-
Power generation and distribution
-
Water and wastewater treatment plants
-
Manufacturing facilities requiring voltage-based monitoring
Typical applications include analyzers, vibration sensors, position feedback devices, or any equipment providing voltage outputs instead of 4–20 mA loops.
Frequently Asked Questions
Can the AAV141 measure current signals?
-
Not directly. To measure 4–20 mA signals, an external 250 Ω shunt resistor is required at the terminal board to convert the current into a voltage (1–5 V) for the module.
Why is the 40 ms update cycle important?
-
This fast data refresh rate allows the DCS to respond quickly to dynamic process changes, maintaining process stability and safety in critical control loops.
