PD663 Loop-Powered Meter Instruction Manual

INTRODUCTION
The ProtEX-Lite PD663 is a rugged, NEMA 4X loop-powered meter in an
explosion-proof enclosure ideal for applications where a simple, inexpensive
display is required in a hazardous area. The PD663 is scaled using four push
buttons and can be done without applying an actual calibration signal.
Programming may also be done through the explosion-proof enclosure with
optional magnetic reed switches and a magnet key. The PD663’s display will
read up to 2999; we call this 3½+ digits! The loop-powered backlighting option
lets you see the display under any lighting condition and is powered completely
from the 4-20 mA loop. This means there is no need for additional wiring and
never any batteries to change. Multi-point linearization with up to 32 points and
the square root function allow for conditioning of signals from non-linear
transmitters without adding external components to the system.
The PD663 is housed in a rugged, explosion-proof, cast aluminum, NEMA 4X
enclosure and is provided with two threaded conduit holes and integrated pipe or
wall mounting holes.
