The module CW-301 makes it possible to switch power relays by means of CAN messages and manual switches. As a consequence, it is possible, for example, to switch on the power supply to mobile measuring equipment by means of a specific CAN bus signal (e.g., KL15) or charge batteries installed in measurement technology to defined vehicle states.
The CW-301 is equipped with three switchable outputs and can be operated with a maximum switching current of 30 A. 10 A thermal circuit breakers protect the manual and CAN controlled circuits.
It is possible to configure a wide range of different settings via the CAN protocol, such as the baud rate, CAN message, sleep mode and follow-on time.
