USB DAQ Simultaneous Data Acquisition Card 8 channel 16bit Analog Input AD 2DA isolated 8DI / 8DO PWM Counter module | Компьютеры и

USB Data acquisition card V5.1 (previous V5.0) is with 8 channels single-ended 16bit High-precision synchronous analog signal acquisition ( the highest stable sampling rate  48KSPS,48X8K Characters per second ) ,2 channel 12Bit analog outputs ,8 channel Digital signal isolation input/ 8 channel digital signal isolation ,1 channel PWM Input, 1channel counter and 2 channel PWM Output.

Mainly for high- precision analog acquisition ,Synchronous acquisition , interference resistance, each module isolation and other industrial occasions , particularly suitable for use in the field of power electronics. 

1. Features:

1. 8 Road 16Bit synchronous acquisition.   only 1mV error In -10V -+ 10V Input gain range; ;
2. Input impedance greater than 1M Ohm , the signal can directly access for most measurements , do not need to pre- impedance conversion circuit , input channel-16-16VClamp protection , while providing7KVOfESDProtection ;
3. Onboard flexible digital first order sinc Filter , may be provided by a flexible digital filtering different oversampling ratio at low sampling rate , the decrease in the signal noise;
4. USB Isolation communication , capture cards and computer use of isolationUSBNo electrical connection between the communication , capture card and a computer , there is no common ground issues that can withstand between the capture card and a computer5KVInstantaneous voltage , even if the external high voltage burn capture card also ensures security of the computer ;
5. Digital IO Opto-isolated inputs and outputs are used , such as to avoid interference relay system to capture card , but also play a role in security isolation .
6. work in linux, Win2000 / XP / WIN7 other popular operating systems , and provides DLL for VB.net, dynamic link library VC, C ++ Builder, Dephi, LabVIEW, Matlab, QT and other common programming language, programming functions interface is simple to use, easy to write applications.
