1.8 Signal contact
The signal contact is a potential-free relay contact.
The device allows you to perform remote diagnosis via the signal contact. In
the process, the device signals events such as a line interruption. When an
event occurs, the device opens the relay contact and interrupts the closed
circuit. The management setting specifies which events switch a contact.
You can also use the management to switch the signal contact manually and
thus control external devices.
