Figure 4-1 Connections on the rear panel of the relay.
The generator protection relay is connected to the protected
object through the following measuring and control
connections, see Figure 4-1:
•

Digital inputs
Further the generator protection relay can collect status
information and alarm signals via six digital inputs (terminals
X3: 2-7).
The digital inputs can be used to:
•
Block protection stages under certain conditions.
•
Get time stamped event code from any auxiliary
contact.
•
Control the output relays.
•
Supervise the trip circuit.
The digital uses the internal 48 V dc auxiliary voltage of the
relay (terminal X3: 1). Potential-free contacts must be available
in the protected object for transfer of status information to the
relay.
