features and benefits
Introduction The A-726 card is new generation product is designed as completely compatible with the A-626. The A-626, A-628 and A-726 are 12-bit AO boards with 16 DI channels and 16 DO channels.
The A-626 and A-726 supports 6 AO channels while the A-628 supports 8 AO channels.
They are supports both current and voltage output range .The each D/A channel can be individually jumper selectable for different voltage range +/-10 V, +/-5 V, 0 ~ 5 V, 0 ~ 10 V and 4 ~ 20 mA (sink) current.
On board reference chip BB Ref-01 is used for solving the thermo-drifting problem of the reference voltage. These cards support various OS versions, such as Linux, DOS, Windows 98/NT/2000 and 32-bit Windows XP/Vista/7.
DLL and Active X control together with various language sample programs based on Turbo C++, Borland C++, Microsoft C++, Visual C++, Borland Delphi, Borland C++ Builder, Visual Basic and LabVIEW are provided in order to help users quickly and easily develop their own applications.
