model
...
number
...
with
...

'-RAAA'
...
for
...
an
...
Enhanced

...
Board
...
with
...
three
...
AC
...
solid
...
state
...
relays.
...
Solid
...

relays
...
offer
...
near
...
zero
...
volt
...
turn-on
...
and

...
This
...
feature
...
makes
...
them
...
ideal
...
options
...
for
...
applications
...
that
...
need
...
to
...
switch
...
inductive
...
loads
...
such
...
as
...
a
...
solenoid
...
or
...
