The LDP63100 Series is a
versatile display that can increase
productivity by offering the plant
floor or production area a large
visual display of their current status.
Whether your measurement needs
are for temperature, voltage, current
or process information, the LDP63100
can satisfy your requirements. The
LDP63100 accepts various analog
inputs which allow the unit to adapt
to most any application. Additional
plug-in option cards add alarms,
analog outputs, and communication/
bus capabilities, making the
LDP63100 an “intelligent” panel
meter. The unit has a large display,
designed to be remotely mounted,
therefore the unit does not have
a programming keypad. Unit
programming can be accomplished
through the use of external switches
that can be wired via the terminal
block; a minimum of 3 switches is
required. An optional programming
remote option provides a
10' interconnecting cable and
programming box. The remote
buttons make programming the
display easy.
