8.2.2. Definition of digital inputs/outputs
The
ekor
.rpa-110-v and
ekor
.rpa-120-v 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 in busbar position
S4
Closing order
E5
Disconnector in open position
E6
Switch in earthing position
E7
Springs loaded
E8
Anti-pumping relay
E9*
Monitoring of the closing coil (in the open and closed positions)
* Where E9 must be associated to open coil monitoring

inputs/outputs
The functionality of the inputs and outputs presented
is typical of cubicle installations: However, there
is always the option of including different or new
configurations. Contact
Ormazabal
's technical-
commercial department in order to ensure new
configurations are properly installed in the functional
unit, or to obtain further information and details.
The inputs and outputs configuration of the relay, signals
accessible from the
ekor
.rpa-110-v and
ekor
.rpa-120-v
terminal block is shown below.
