Data Capture Card
- ADC1,5PCI
Application
Data capture with further writing it on the disc or
with further processing in real time mode. Multichannel digital
registers and analyzers building (forming). It can be well used
instead of analog self-writers and recorders.
Special characteristics
- 12 bit ADC; conversion time: 2 ms
- 32 single-ended channels (16 differential)
- input impedance: more than 100 MOhm
- ADC input voltage ranges (program switching): ± 10V, ± 5V,
± 2,5V, ± 1V, ± 0,5V, ± 0,25V, ± 0,1V, ± 0,05V (for each channel)
- effective bits number: 11,2 (input signal frequency 5 KHz)
- Bus-Master mode data transfer; a capacity of generating an
interruption in any data cell of the buffer
- FIFO type buffer memory: 2048 Words
- high-stabil chrystal generator (50 MHz) and a programmable
frequency devisor: from 5 upto 31 for a timer provides a wide
range of sampling rates
- 16 digital lines: 8 - input and 8 - output
- three16-bit counters
- input DHS-26 for digital lines and DHS-44 for analog
Application
- multichannel data capture
- automated systems of technological processes control
- digital oscilloscope
- selt-recorder
