March 16, 2016 - Data Translation announces DT9857E USB data acquisition module that has eight or 16 analog inputs (24-bit), two 32-bit analog outputs, digital I/O lines, tachometer input and counters.
The analog inputs can be configured to suit specific requirements, an IEPE/ICP sensor current source is individually programmable. The flexible supply voltage range from 4.75 to 28 VDC makes this module suitable for vehicle-based test and measurement applications.
Each analog input channel is provided with a 24-bit A/D converter and integrated anti-aliasing filters, the maximum sampling rate per channel is 105.4 kHz. For each input, a separate 4 mA IEPE/ICP sensor current source can be programmed, and a user can select between AC and DC coupling and input ranges of ±10 V or ±1 V. In addition to the analog inputs, the USB data acquisition module features two analog outputs (32-bit, 216 kHz), one 32-bit tachometer input (±30 V), various counters as well as eight digital inputs and outputs. Multiple hardware trigger functions are conveniently configurable by software.
Both the analog inputs and the analog outputs of two or more modules can be synchronized easily using sync cables. This way, it is possible to implement measurement systems with 32 or more analog inputs and a corresponding variety of analog outputs and digital I/O functions without great effort.
The DT9857E module is available both as a robust BNC-boxed version and a board version for integration into OEM devices. The module comes with 32/64-bit drivers for common Windows operating systems, many useful programming tools and interfaces as well as the proprietary QuickDAQ data logger application, which can be upgraded with FFT-options for spectral analysis.
