Analog
...
Inputs
The FAC-2100
...
contains
...
three
...
analog
...
inputs
...
each
...
capable
...
of
...
operating
...
in
...
current,
...
voltage,
...
resistance,
...
or
...
RTD
...
measurement
...
modes.
...
The
...
modes
...
are
...
software
...
controlled
...
and
...
all
...
internal
...
circuitry
...
reconfiguration
...
is
...
automatic
...
(i.e.
...
no
...
external
...
jumpers
...
are
...
required).
...
Select
...
from
...
one
...
of
...
the
...
following
...
modes

The
...
internal
...
controller
...
electronics
...
will
...
automatically
...
isolate
...
themselves
...
from
...
the
...
external
...
circuitry
...
via
...
a
...
high
...
impedance
...
switch
...
when
...
the
...
analog
...
input
...
is
...
either
...
not
...
configured
...
for
...
use
...
in
...
the
...
software
...
or
...
the
...
unit
...
is
...
powered
...
off.
...
The
...
required
...
configuration
...
will
...
automatically
...
become
...
connected
...
(i.e.
...
low
...
impedance)
...
when
...
the
...
device
...
is
...
powered
...
and
...
the
...
input
...
is
...
configured
...
for
...
a
...
particular
...
function.

Replacing FAC-2000

Controllers

with
...
FAC-2100s
...
Note
...
that
...
the
...
FAC-2000
...
(the
...
previous
...
model
...
FAC-2100)
...
did
...
require
...
external
...
jumpers
...
to
...
configure
...
the
...
inputs.
...
The
...
FAC-2100
...
is
...
100%
...
backwards
...
compatible
...
with
...
the
...
FAC-2000
...
and,
...
if
...
those
...
jumpers
...
are
...
installed,
...
they
...
do
...
not
...
need
...
to
...
be
...
removed
...
when
...
replacing
...
the
...
FAC-2000
...
with
...
a
...
FAC-2100.
