Description
The PIO-DA series are multi-channel D/A boards for the PCI bus for PC. The PIO-DA16/8/4/16U offer 16/8/4 channels double-buffered analog output. The output range may be configured in range: ±10V voltage output or 0~20mA current loop sink. The innovative designed 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.
The PIO-DA16U Universal PCI card supports both 5V and 3.3V, while the PIO-DA16/DA8/DA4 PCI card supports 5V PCI bus only. The PIO-DA16U (Universal PCI Version) is fully compatible with the PIO-DA16 (PCI Version), and also has an improvement in D/I pull-high/low design. The PIO-DA16U cards are designed as direct replacements to the PIO-DA16 cards for RoHS reason.
Note: This card needs a +12V power supply, which can be found in most regular PC's or Industrial PC's.
