Analog output card DNx-AO-318 series

8-channelvoltagecurrent

The DNx-AO-318 are fully isolated, high-precision, 8-channel analog voltage output boards, compatible with UEI's popular Cube, RACKtangle and FLATRACK I/O chassis respectively. The boards offer full 16-bit resolution and guarantee monotonicity over the entire operating temperature range. Each DNx-AO-318 channel provides an output range of ±10 V and is capable of driving ±10 mA. For applications requiring higher output current or voltage, please refer to the DNx-AO-308-35x series boards. The DNx-AO-318 provides extensive built-in-test diagnostics. An onboard A/D converter on each channel allows the user to monitor both output voltage and current. A solid state relay on each output allows the D/A channel to be disconnected from the field I/O so that a complete board self-test can be completed without driving the circuitry connected to the outputs. This relay in combination with the output current and voltage sensing can also be set to disconnect the D/A output in the event of an external fault condition such as a short to ground or a DC power supply. All 8 channels may be configured to update simultaneously, or they may be updated one at a time as data is written. A 1024 sample FIFO allows each D/A to be updated at 10 kHz without data loss. Double buffering the outputs combined with the use of low glitch D/As make the DNx- AO-318 an ideal solution for generating low frequency waveforms or providing highly accurate switched stimulus.
