Contec AO-1604LI-PE - Isolated 16-bit Analog Output Board for PCI Express

4 16-Bit Analog Isolated Outputs, 8 Digital I/O Channels & 1 Counter


Contec's AO-1604LI-PE is a PCI Express bus-compliant interface board used to provide an analog signal output function on a PC. It features bus isolated 16-bit analog output 4 channels. Equipped with digital I/O and counter, this product is multifunction and bus isolated type that provides isolation between PC and external analog I/O circuit. This product carries buffer memory for 1K of data, allowing sampling to be performed in a variety of trigger / clock conditions. Windows/Linux driver and full-fledged data logger software [C-LOGGER] is bundled with this product.


  • This product has analog output (10uSec, 16-bit, 4 channels), analog output control signal (TTL level 3 channels), digital I/O (each 4 channels for TTL level), counter (32-bit, TTL level 1 channel).
  • 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.
  • Isolation between PC and external analog output circuit by a digital isolator improves noise performance.
  • You can select from software, comparison of conversion data or an external trigger to control the start of sampling. You can select from completion of sampling for a specified number of sessions, comparison of conversion data, an external trigger or software to control the end of sampling. The sampling cycle can be selected from the internal clock or an external clock..
  • To prevent the unstable voltage and the connected device of D/A converter from fault and malfunctions when the power supply is turned on, the circuit is designed to adjusts output voltage of the analog output to 0V.
