Signals
The
DC
isolated
input
signals
are
connected
to
the
cathodes of
the LEDs
in
the
opto-isolators
.
The
anodes
of
the
LEDs
are
powered
by
an
external voltage
source (EXT
DCV2).
The
OFF
state
voltage
(high
level)
of
the
DC
isolated input
signals depends
on the
pull-up
voltage
powered
by
an
external
voltage
source
(EXT
DCV2).
(The input
current is
restricted by
using
a
switch
on
the
main
board.)
The
electrical characteristics
of the
input signals
are listed
in
T
able

.
A
diagram
for
the
input
signals is
shown in
Figure B-3
