PCI-20098C Overview

These PC data acquisition boards were designed with flexibility in mind. All of the most popular analog/digital I/O features are already on board, plus you can expand the on-board I/O capabilities by adding up to two plug-in option modules. Using the option modules, you can increase the number of analog input and digital I/O channels and counters, or add analog outputs, simultaneous sample/hold, or analog triggering functions.
