Extension of a WB component by up to four potential-free changeover contacts
WBex DO4 is used to expand a WB component with up to four potential-free changeover contacts.
To do this, the Wbex DO4 component is connected to the internal WB bus.
This can be used, for example, to switch up to 4 actuators or to transmit up to 8 operating states to the SCADA system
