DNR-AI-205 |
 |
| 4-channel, 18-bit, 250 kS/s per channel, simultaneous sampling analog input, data acquisition board for the PowerDNR RACKtangle® |
 |
 |
| |
The DNA/DNR-AI-205 is a powerful and unique analog input data acquisition board, compatible with popular "CUBE"/RACKtangle® chassis respectively. The board offers 4 A/D channels with input ranges up to ±100 volts, 18-bit resolution, 250 kS/s Simultaneous sampling and full channel-to-channel isolation. The board also features a three stage polyphase FIR filter that provides digital filtering capability in real-time. There is nothing like this board available anywhere else at any price. |
