Description
Alarm outputs are sent to

the DC power
distribution cabinet
through the output
interface and the
cascading interface. You
can configure it to be the
other outputs to
implement integrated
display of alarms. The
alarm outputs are
controlled by the internal
relay contact. When the
relay contact is closed,
the resistance of each
ALMO interface is less
than 1 ohm. When the
relay contact is open, the
resistance of each
ALMO interface is an
infinite number.
The ALMO1 and

ALMO2 interfaces have
the same pin usage and
are a pair of
housekeeping alarm
output/cascading
interfaces. Similarly, the
ALMO3 and ALMO4
interfaces also have the
same pin usage and are
another pair of
housekeeping
output/cascading
interfaces. For example,
when ALMO1 and
ALMO3 are used to
output housekeeping
alarm signals, ALMO2
and ALMO4 can be
cascaded to ALMO2 and
ALM04 on another
subrack.
