Product Description
The AAI543 is a 16-channel high-density analog output module for Yokogawa CENTUM VP and CS 3000 DCS systems. It converts digital control commands into isolated 4–20 mA signals to drive valve positioners, actuators, variable speed drives, and other current-driven devices.
Designed for high availability, each channel features galvanic isolation, protecting system logic from field-side interference and preventing ground loops. The module is available in multiple configurations, including HART-enabled versions for smart device integration and G3-rated versions for corrosive environments.

Application Use Cases
The AAI543 is widely deployed in:
-
Oil and gas refining
-
Chemical manufacturing
-
Power generation
Its 16-channel density optimizes rack space, while isolated channels ensure that a fault on one actuator does not affect the others, supporting mission-critical process control.
FAQ
Can the AAI543 be used as an input module?
-
No. This is strictly an Analog Output module. For inputs, use the AAI141 or AAI143 series.
Which terminal blocks are compatible?
-
Pressure Clamp Terminals: Direct wiring (e.g., A4S00, A4D00).
-
KS Cable Interface: For remote terminal board connection (e.g., K4A00 with ATK4A-00 adapter).
