Technical Reference Manual
For detailed technical data of the outputs, refer to Section 7.1. Technical data.
Configuration
High speed double-pole power output (HSPO)
The high-speed power outputs PSC_7_HSPO1 and PSC_7_HSPO2 can be
connected as double-pole outputs where the object to be controlled (for example a
circuit breaker) is electrically connected between the two relay contacts, see figure
below. The high-speed double-pole power output is preferred for the control of
disconnectors.
e.g.
PSC_7_HSPO1
PSC_7_HSPO2
Fig. 5.5.2.1.-1 High-speed double-pole power outputs PSC_7_HSPO1 and
PSC_7_HSPO2
The high-speed power outputs PSC_7_HSPO1 and PSC_7_HSPO2 can also be
connected as single-pole power outputs where the object to be controlled (for
example a circuit breaker) is electrically connected in series with the two relay
contacts, see Fig. 5.5.2.1.-2 .
e.g.
PSC_7_HSPO1
PSC_7_HSPO2
Fig. 5.5.2.1.-2 High-speed single-pole power output (HSPO)
Signalling output (SO)
The signalling output is not a heavy-duty output and thus it cannot be used for
controlling a disconnector without external interpose relays. Available SO contacts
are either Normally Open or Normally Open/Normally Closed type contacts (NO or
NO/NC), see the figure below.
