The current measurement interface provides 8 channels with which it is possible to measure currents from -5.8 A to +5.8 A. The measured data can be output both via CAN bus and by means of an analog voltage signal. The maximum output transfer rate via CAN bus is 2 ms. Setting options, such as cycle time, CAN message ID and baud rate can be set via the CAN protocol.

The CW-328 is particularly suited for performing component tests and simulations on HiL test benches. Furthermore, it is practical to deploy this module in all other situations in which currents are to be measured in close proximity to the test specimen. This reduces costs for cabling as well as susceptibility to EMI noise.

In conjunction with the bus technology modules CW-101 and CW-102 it is possible to transfer measurement data via USB or Ethernet to a PC on the one hand, and to alter the configuration of the module on the other. A software API written in C/C++ and C# facilitates incorporating the module in proprietary programs.
