The
...
FAC-2100
...
can
...
be
...
special
...
ordered
...
with
...
an
...
enhanced
...
relay
...
board
...
that
...
can
...
include
...
up
...
to
...
three
...
DC
...
or
...
AC
...
solid-state
...
form
...
A
...
relays
...
(see
...
figure
...
above.)
...
Each
...
solid-state
...
relay
...
is
...
capable
...
of
...
switching
...
3
...
amp
...
resistive
...
or
...
inductive
...
loads
...
at
...
60V
...
DC
...
or
...
140
...
V
...
AC.
...
Each
...
solid-state
...
relay
...
must
...
be
...
individually
...
specified
...
as
...
AC
...
or
...
DC
...
when
...
ordered.
...
You
...
may
...
not
...
use
...
the
...
AC
...
type
...
to
...
switch
...
DC
...
signals
...
and
...
visa-versa.
...
Do
...
not
...
use
...
the
...
solid-state
...
modules
...
to
...
switch
...
low
...
currents
...
as
...
they
...
typically
...
have
...
a
...
4-mA
...
leakage
...
current
...
in
...
the
...
off
...
state.
...
Use
...
a
...
mechanical
...
relay
...
if
...
it
...
is
...
necessary
...
to
...
switch
...
low
...
current.
...
Keep
...
in
...
mind
...
that
...
DC
...
solid-state
...
relays
...
have
...
defined
...
polarities
...
– the
...
terminals
...
labeled
...
common
...
(COMM)
...
are
...
positive
...
and
...
those
...
labeled
...
normally
...
open
...
(N/O)
...
are
...
negative.
...
Also,
...
note
...
that
...
the
...
AC
...
solid-state
...
modules
...
are
...
zero
...
crossing
...
turn-on.
...
This
...
means
...
that
...
the
...
modules
...
will
...
not
...
energize
...
until
...
the
...
input
...
waveform
...
crosses
...
zero
...
volts.
...
This
...
translates
...
to
...
a
...
maximum
...
switching
...
delay
...
of
...
approximately
...
half
...
the
...
AC
...
line
...
frequency.

On FAC-2100
...
units
...
equipped
...
with
...
miniature
...
cylindrical
...
connectors,
...
some
...
relay
...
outputs
...
may
...
have
...
additional
...
current
...
carrying
...
limitations
...
imposed
...
by
...
the
...
connector
...
pin.
