4263B
Input
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
Table
B-2.
A
diagram
for
the
input
signals
is
shown
in
Figure
