Product Description
The AAI543-H50/A4S00 is a high-density 16-channel analog output module designed for Yokogawa CENTUM VP and CENTUM CS 3000 control systems. It delivers precise 4–20 mA DC output signals to field devices such as control valve positioners and actuators. The module supports HART digital communication, enabling remote diagnostics, configuration, and asset management of smart field instruments without disrupting the analog control signal.
This configuration includes the /A4S00 factory option, which provides a pre-installed ATA4S-00 pressure clamp terminal block. This allows direct field wiring at the module face and eliminates the need for external cabling adapters. Built for high-availability control systems, the AAI543-H50/A4S00 supports dual-redundant installation with standard switch-over performance to maintain stable process operation during module transitions.

Frequently Asked Questions
Q: Is the AAI543-H50/A4S00 suitable for hazardous (Class 1 Div 2) environments?
A: No. The H50 variant does not provide explosion protection. For hazardous area installations, an Ex-certified model must be specified.
Q: Can the ATA4S-00 pressure clamp terminal block be replaced?
A: Yes. The ATA4S-00 terminal block is modular and can be replaced independently without removing or replacing the entire AAI543 module.
