The CW-321 facilitates controlling and switching up to 6 high-performance relays via a CAN bus. In conjunction with its top-hat rail housing (45 mm to DIN) the CW-321 module offers a fast and simple solution to automate switching higher currents, for example in component tests on HiL test benches as well as in a wide range of different tasks in automation technology.
The selected state encoding of the relay in the CAN messages allows both targeted actuation of a single relay channel as well as the simultaneous switching of several relays.
The CW-321 is designed to directly control high-performance relays in vehicles as a standard function. It is possible to implement customer-specific modifications for other relay versions at any time.
In conjunction with our bus technology modules CW-101 and CW-102 it is possible to connect the CW-321 directly to a notebook or PC. Control functions are performed with the aid of the software CW-901.
