We have expanded our CW-300 series for test bench technology with the CW-324, a module with 16 sink mode outputs. It is possible to set each current sink between 0 and 20 mA with a high 12 bit resolution. Furthermore, the amperage can be redefined 100 000 times per second and all 16 channels synchronized.

The maximum switching speed of individual voltages depends on 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-324 is particularly suited for performing component tests and simulations on HiL test benches. Furthermore, it is practical to deploy this model in all situations in which a certain current is to be applied to the test specimen.


  • 16 current sinks, freely selectable between 0 and 20 mA
  • Control via CAN bus
  • 12 bit resolution per channel
  • Switching speeds up to 100 kHz
  • All outputs can be synchronized
  • Quick and easy to install, suitable for top-hat rail (45 mm to DIN)
  • Easy to extend and scale channels
