Contec AI-1664LA-LPE - 64 Channel 16-bit Analog Input Board for Low Profile PCI Express

64 16-Bit Analog Inputs, 8 Digital I/O Channels, 100 KSPS


Contec's AI-1664LA-LPE is a Low Profile, PCI Express bus-compliant interface board used to provide an analog signal input function on a PC. This product is multi-channels and multifunction type with 16-bit analog input 64 channels (single-ended input 64 channels or differential input 32 channels), digital I/O and counter function. This product carries buffer memory for 1K of data, allowing sampling to be performed in a variety of trigger / clock conditions. The board has a full driver library (API-PAC(W32)), which supports Visual C# .Net, Visual Basic .Net, Visual C++. Also, the product supports no-programing data collection with a data logger soft (C-LOGGER), and supports MATLAB and LabVIEW with plug in of an exclusive library (free download).


  • This product has analog input (10uSec / channel, 16-bit, 64 channels), analog input control signal (LVTTL level 3 channels), digital I/O (each 4 channels for LVTTL level) and counter (32-bit, LVTTL level 1 channel). Capable of setting the analog input at single-ended input 64 channels and differential input 32 channels.
  • The functions same with PCI compatible board DAI16-4(LPCI)L are provided. In addition, as there is compatibility in terms of connector shape and pin assignments, it is easy to migrate from the existing system.
  • The analog input / output block contains buffer memory (1K data) that can be used in the FIFO or RING format. This allows for background analog I/O that does not depend on the operation status of the software or PC.
  • You can select from software, an external trigger to control the start of sampling. You can select from completion of sampling for a specified number of sessions, an external trigger or software to control forcibly the end of sampling. The sampling cycle can be selected from the internal clock or an external clock..
  • The functions same with PCI compatible board AD16-64(LPCI)LA are provided. In addition, as there is compatibility in terms of connector shape and pin assignments, it is easy to migrate from the existing system.
