SMARTE Messtechnik für Gleichstrom – Spannung – Kabel – Isolation
Extension of a WB component by up to four potential-free changeover contacts
WBex DO4 is an extension of WB components with up to four potential-free changeover contacts. The extension is connected to the internal WB bus for this purpose.
With the WBex DO4 extension, for example, up to four actuators can be switched. It can also transmit up to eight operating statuses to the SCADA system.
