Card ISA 8 kênh cách ly AO ICP DAS ISO-DA8 CR

The ISO-DA8 is bus-type isolated 14-bit D/A card for PC/AT compatible computers. The optical isolation of the ISO-DA8 can operate with up to 2500 VDC of common-mode voltage. The ISO-DA8 offers 8-channel double-buffered AO. The output range may be configured from these ranges : +/-10 V, +/-5 V, 0~10 V, 0~ 5 V voltages output or 4 ~ 20 mA or 0 ~ 20 mA current loops sink. The board*s innovative design improve several drawbacks of the conventional isolated D/A card . For example : 1. Jumperless,Trimless 2. The power-on value of AO can be pre-defined by the user and stored in the on board EEPROM 3. High channel count output can be designed implemented in half size. 4. The calibration is performed under software control, thus eliminating manual trimpot adjustments. The calibration data is stored in EEPROM. Easy recalibration ensures the accuracy of the board.
  • Programmable voltage source
  • Programmable current sink
  • Harsh environment operation
