PMC730: PMC Multifunction I/O Module

PMC730 mezzanine modules provide a variety of I/O functions on a single plug-in card. These high-density PMC modules perform both high-speed and high-resolution A/D and D/A conversion and also handle digital I/O and counter/timer functions.

Now you can conserve your precious PMC slots and still get all the I/O functionality you need. The PMC730 is designed for extreme versatility with many deluxe features to meet most applications. However, the PMC730 is still very budget-friendly. A conduction-cooled version is also available.
