CW-323

D/A CONVERTER

We have expanded our CW-300 series for test bench technology with the CW-323, a module designed to output 16 analog voltages. It is possible to freely select these voltages between 0-5 VDC with a high 12 bit resolution. The voltage outputs are controlled via the CAN bus. If required, it is possible to synchronize all 16 voltages.

The maximum switching speed of individual voltages is independent of the bus system. Customer-specific modifications are possible, which when implemented it is possible to output any stored waveforms with switching speeds of up to 100 kHz.

Consequently, the CW-323 is particularly suited for performing component tests and simulations on HiL test benches. In addition, there are practical reasons to deploy this model in all situations where it is envisaged generating voltages close to the test specimen, e.g., to avoid costly cabling or to apply the voltages as noise-free as possible to the test specimen.

PERFORMANCE CHARACTERISTICS

  • 16 user programmable output voltages between 0 VDC and 5 VDC
  • 12 bit resolution per channel
  • Control via CAN bus
  • Selective control of a single channel or simultaneous control of several channels possible
  • All outputs protected against overvoltage, polarity reversal and short circuiting
  • Quick and easy to install, suitable for top-hat rail (45 mm to DIN)
  • Easy to extend and scale channels
