4.2.4.5.7 Digital outputs
For means of communication, operation and display
functions, software of relay operates using three types
of internal signals:
- Trip
- Pickup
- Command/control
Control matrix can be used to assign internal signals of
individual elements (etc. individual protections) to
interact with output relays or LED indicators. The Figure
4.23 represents selection of Digital outputs menu.

Relay basic options can be found in Relay settings
submenu. According to general purpose for each
individual output relay a basic options can be set.

Logic
Digital output logic defines state of specific output relay
at non-active position.
Pulse width
States time which defines output relay to be active after
certain signal become apparent.
Only for trip relay a trip signal has priority
over pulse width setting.

Relay mapping
Trip relay, Close relay 1, Close relay 2 and Ready relay
are mapped in Relay mapping menu. Also open
commands are executed on trip relay.

Ready relay can be mapped only to DO6. In
case if it is mapped to ready relay the
setting logic: Active-OFF is not taken into
account.
