Product Description
The AAI543-H00/K4A00 is a high-density 16-channel isolated analog output module designed for Yokogawa CENTUM VP and CENTUM CS 3000 distributed control systems (DCS). It delivers precise 4–20 mA signals to drive field actuators while supporting HART digital communication for remote device diagnostics and configuration.
The /K4A00 KS cable interface facilitates fast, organized cabinet assembly and seamless connection to terminal boards.

Application Scenarios
The AAI543-H00/K4A00 is ideal for control valve positioners, motor speed controllers, and other current-driven actuators in process industries.
Its 16 isolated channels and support for dual-redundant operation make it a reliable solution for critical control loops where maintaining process continuity is essential.
Technical FAQ
Q: Does this module support digital communication with field devices?
A: Yes. The module supports HART communication, enabling transmission of secondary variables and device diagnostics alongside the 4–20 mA analog signal.
Q: What happens if a field wire is disconnected?
A: The module features circuit-open detection. If loop current drops below 0.65 mA, the system flags a potential wiring fault, allowing for quick troubleshooting and maintenance.
