8.3.2. Definition of digital inputs/outputs
The ekor.rpa-110-p and ekor.rpa-120-p protection,
metering and control units are fitted with a series of
physical inputs and outputs that are isolated from the other
independent circuits (terminals X2). The standard definition
of the inputs and outputs is as follows:
Physical inputs Physical ouputs
E1
External trip
S1
Trip indication
E2
Switch closed
S2
Watchdog
E3
Switch open
S3
Opening sequence
E4
Disconnector closed

Table 8.5. Ratio of signals available for the nine inputs and
four outputs module
The specific functions of the inputs and outputs
depend on the installation and can be different to that
shown in the tables above. Please see the installation
diagrams to check the specific functions of these
inputs and outputs.
The inputs and outputs configuration of the relay, signals
accessible from the ekor.rpa-110-p and ekor.rpa-120-p
terminal block for 9 inputs 4 outputs is shown below.
