Product Description
The AAI543-H53 S1 is a high-density analog output module designed for precise control within the Yokogawa CENTUM VP distributed control system. It provides 16 channels of 4–20 mA current outputs, making it ideal for driving final control elements such as pneumatic valve positioners, actuators, and variable speed drives.
The module supports HART digital communication, allowing bidirectional exchange of diagnostics and device status with smart field instruments. As a Style S1 (hardware version 1) unit, the AAI543-H53 S1 is engineered for long-term stability and high availability in continuous process environments. The H53 configuration indicates HART capability with a pressure-clamp terminal interface, intended for standard, non-hazardous installations.

Large-scale process units with high valve density
Its 16-channel output density minimizes I/O footprint, while HART support enables remote valve diagnostics and improved maintenance efficiency.
Frequently Asked Questions
Does the AAI543-H53 S1 support redundancy?
Yes. When installed on a redundancy-capable Yokogawa I/O baseplate, the module can operate in dual-redundant configurations to maintain loop availability.
What does the H53 suffix indicate?
The H53 designation identifies HART communication support and a pressure-clamp terminal interface, without explosion protection, suitable for standard industrial areas.
