Product Description
The AAV544-S50 is a high-density analog output module for Yokogawa Electric Corporation’s FIO (Field network I/O) system, widely used in CENTUM VP and ProSafe-RS control systems. It provides 16 isolated voltage output channels for precise control of actuators, signal conditioners, and motor controllers.
The "S50" suffix indicates standard conformal coating for ISA G3 environmental protection, offering resistance to corrosive gases and harsh plant conditions common in chemical, paper, and wastewater treatment facilities.

Industrial Applications
The AAV544-S50 is ideal for multi-point voltage control loops where isolation is critical to prevent cross-channel interference. It is commonly applied in:
-
HVAC and environmental control systems
-
Laboratory automation setups
-
Specialized chemical dosing and process control systems
Its isolated channel architecture protects the control system from field-side electrical noise and ensures safe operation in complex industrial environments.
Professional FAQ
Can the AAV544-S50 provide 4–20 mA outputs?
No. This module is voltage-only. For current output applications, the AAI543 series should be used. A 250 Ω resistor can be used with this module to emulate a 1–5 V loop signal.
Does it support dual-redundant operation?
Yes. Two modules can be installed in a redundant I/O slot configuration for critical control loops, maintaining output if one module fails.
Why is channel-to-channel isolation important?
Isolation prevents ground loops and ensures that a fault on one field device does not affect other channels or the system backplane, enhancing reliability and safety.
