The mPCIe-AIO16-16F is an ideal solution for adding high-speed analog I/O capabilities to any computer with an mPCIe slot.

The mPCIe-AIO16-16F is a 16-bit resolution A/D & D/A board with two simultaneous 1MHz A/D converters, providing 8 single-ended (pseudo-differential) or 4 differential analog inputs, per ADC. Each channel can be independently software configured to accept any input ranges.

Two digital I/O bits, each individually software programmable for use as an input or an output. These bits feature software-selectable alternate functions including use as ADC trigger, DAC trigger, and more.

Four analog outputs with uni- and bipolar 5 and 10 volt ranges and a ±2.5V range round out the feature set.

This tiny analog I/O board provides the user with everything needed to start acquiring and controlling signals in a variety of applications. The mPCIe-AIO16-16F data acquisition board can be used in many current real-world applications such as embedded equipment monitoring, precision PC-based and portable environmental measurements, and mobile data acquisition. The board is designed to be used in rugged industrial environments and is double sided, mPCIe F1 sized.

Applications: Optical Networking, Instrumentation, Multichannel Data Acquisition and system monitoring, Automatic Test Equipment, Process Control and Industrial Automation, Power line monitoring.

Special Order
