The LDP Series large displays have
high output red or green displays for
easy viewing in most applications.
The LDP-12x has 2.3" digits which
can be seen from 50' away, and the
LDP-14x has 4" digits which can be
seen from 200'.
The rugged extruded aluminum
cases can be either free standing,
mounted in a panel or on a flat
surface (optional wall mount
bracket required).
