Product Description
The AAI543-H50 S1 / ATK4A-00 S1 is a high-density, isolated analog output module for Yokogawa CENTUM VP and FIO systems. It provides 16 fully isolated channels to drive 4–20 mA signals for field devices like control valves, actuators, and variable frequency drives. Integrated HART communication enables real-time smart device diagnostics.
The S1 bundle includes the factory-mounted ATK4A-00 adapter, providing a KS Cable Interface for rapid, plug-and-play connection to AEA4D terminal boards, greatly simplifying cabinet wiring.

Application Scenarios
The AAI543-H50 S1 is used in mission-critical industrial control loops, including:
-
Refineries and chemical plants for valve modulation
-
Power generation plants for motor speed control
-
Any high-density actuator control where electrical isolation and reliability are mandatory
Its isolated channels ensure that a fault in one loop does not propagate, supporting continuous, high-reliability operation.
Technical FAQ
Q: Is this an input or output module?
A: The AAI543 is strictly an Analog Output module. (For input, use the corresponding AAI143 series.)
Q: What is the benefit of the ATK4A-00 S1 bundle?
A: It comes pre-assembled with the module, allowing a single KS cable to connect all 16 channels to a terminal board, drastically reducing installation time and wiring errors.
Q: Can this module be used in a redundant setup?
A: Yes, it supports dual-redundant configurations with standard switch-over response to maintain continuous process control during module replacement or failure.
