INTRODUCTION

The PD663 is a rugged, explosion-proof NEMA 4X loop-powered meter perfect for applications where a simple, inexpensive display is required in a hazardous area.

The PD663 derives all its power from the 4-20 mA loop. The PD663 is scaled using four push buttons and can be done without applying an actual calibration signal, and 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.

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.

QUICKSTART

The PD663 is designed to be easily wired into your current loop and quickly programmed.

Wiring

The two wire power/signal connection is made on the back of the PD663 on the three position removable terminal block. Follow instructions printed on the unit for two wire loop-powered connections with or without backlight.

PROGRAMMING;

The PD663 comes calibrated and scaled at the factory to display a 4.00 to 20.00 mA signal on startup. To change the scaling, follow along using the 4 button interface.
