PMC230A: 16-Bit D/A Analog Output

PMC230A: 16-Bit D/A Analog Output Description

PMC230A modules have eight 16-bit D/A converter (DACs) to provide highly-accurate analog voltage outputs. A unique two-piece board design brings the proven reliability of Acromag’s IndustryPack^® (IP) A/D modules to a PMC format. An IP230A module is embedded on a PMC interface card that maintains maximum performance and transparent communication to the host.

Jumper-selectable output ranges give you the choice of unipolar or bipolar voltage output. And for greater flexibility, the PMC230A module accepts conversion start triggers from software commands, or from external sources for synchronization to specific events.

The PMC230A is a drop-in replacement for the PMC230, please see the known differences document below for more information.
