Connect external load devices e.g. contactors, pilot lamps, solenoid (electromagnetic)
to output terminations of the base unit and extension unit (if used).
The
load
limitation
of
the transistor outputs
is
1A
for
each individual output, but
output load should not exceed
2A
per
4
points
at
DC
24V.
Due to surge current limitations lamp loads should be within
3W.
When other load are connected
to
a
output termination in addition to lamp load, the total collec-
tive
output load should be
as
specified with reference to following table.

2A rated back-up fuses or protectors are recommended per each four outputs to prevent damage
to the circuit boards of the

short circuit fault in one
of
