PD662 Loop-Powered Meter Instruction Manual
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.

Mounting
The PD662 can be wall mounted using the mounting holes beneath the
cover screws. A ½” NPT pipe conduit hole is provided. It can be panel
mounted with the addition of the PDA6624 panel mount kit. It can also
be pipe mounted by using the PDA6845 pipe mount kit.
Refer to Mounting Dimensions, page 28 for details on wall or panel
space requirements.
The unit shall be installed in a way that will prevent
any accidental contact of the internal meter circuits
and power supply lines.
Cable suitable for outdoor use and a CSA Approved
gland rated 4X, or a suitable conduit and a CSA
Approved connector rated 4X, is intended to be used
in final installation.
Metallic conduit shall be reliably bonded to protective
earth/ground without creating any ground loop.
PD662 Connections
Disconnect power before opening the unit.
To access the connectors, remove the enclosure cover and unscrew the
two captive stainless steel screws on the rear mounting board. Remove
the meter assembly from the enclosure. Signal connections are made to a
three-terminal removable connector. The signal wiring terminal block is on
the rear of the meter assembly.
