INTRODUCTION
The PD662 NEMA 4X, CSA Certified loop-powered meter is perfect for
applications where a simple, inexpensive display is required and AC
power is not available. The PD662 derives all its power from the 4-20 mA
loop. The PD662 is scaled using four push buttons and can be done
without applying an actual calibration signal. The PD662’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 PD662 is housed in a rugged NEMA 4X enclosure and is provided
with one ½" NPT pipe conduit hole. The PD662 is also available with an
optional DC-powered heater that allows the PD662 to operate in
temperatures as low as -55°C.
