The bus and signal multiplexer module is a further product belonging to the CW-300 series for test bench technology and test bench automation. Utilizing the CW-325 it is possible to control the signal paths of bus systems such as CAN bus and FlexRay™ or any desired signal.

The signal paths are connected, disconnected or diverted by means of commands via a control CAN. It is possible to activate terminating resistors for termination purposes for bus systems or to divert the buses to a diagnostics gateway. 17 signal relays are available for these functions.

The open design in the top-hat rail housing (45 mm to DIN) offers the user a quick and easy solution to automate procedures in test bench technology.

The CW-325 is a component of the CW-300 series from CANWAY. The entire series is based on a modular design with a CAN bus interface that can be combined according to requirements of the respective application.


  • Switch up to 5 bus systems or signals
  • 17 switchable signal relays to set the signal paths
  • Control via CAN bus
  • USB and Ethernet interfaces are also available in conjunction with the CW-101 or CW-102
  • Top-hat rail housing for quick and easy installation
  • Easy to extend and scale
