产品描述The OME-PIO-DA16U, OME-PIODA8U and OME-PIO-DA4U are multi-channel D/A boards for the PCI bus for IBM or compatible PC. The OME-PIO-DA16U/8U/4U offer 16/8/4 channels of double-buffered analog output. The outputs may be configured in different ranges: ±10 V, ±5 V, 0 to 10 V, 0 to 5 V voltage output or 4 to 20 mA, 0 to 20 mA current loop sink. The innovative design improves several drawbacks of conventional D/A boards. For example: 1. No jumper or trim-pots on the board. 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 a half size card.
