PCI-BUS 4 / 8 / 16-ChannelAnalog Output Card

The PIO-DA16, PIO-DA8 and PIO-DA4 are multi-channel D/A boards for the PCI bus for IBM or compatible PC.
The PIO-DA16/8/4 offer 16/8/4 channels double-buffered analog output. The output range may be configured in different ranges: ±10V, ±5V, 0~10V, 0~5V voltage output or 4~20mA, 0~20mA current loop sink.
The innovative design improves several drawbacks of the conventional D/A boards. For examples: 1. Jumperless and without trim-pot. 2. The calibration is performed under software control eliminating manual trim-pot adjustments. The calibration data is stored in EEPROM. 3. Each channel can be selected as voltage or current output. 4. High channel count output can be implemented in half size.

Note: This card need +12V power supply. It can be found in regular 
           PC or Industrial PC.
