INTRODUCTIONThe 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. QUICKSTARTThe PD663 is designed to be easily wired into your current loop and quickly programmed.WiringThe 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. PD663 Input Connections with Backlight  PD663 Input Connections 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. PD663 Menu Progression  PD663 Face Plate DIMENSIONS SPECIFICATIONSExcept where noted all specifications apply to operation at +25°C.GeneralDisplay: 0.6" (15.24 mm) LCD, 3½+ digits; -1999 to 2999Display Update Rate: 2 Updates/Second Over-Range: Display Flashes 2999 Under-Range: Display Flashes -1999 Programming Method: 4 Front Panel Pushbuttons (behind glass). Magnet may also be used for programming; P/N PDA-MAG. Noise Filter: Programmable HI, LOW, or OFF Recalibration: Recalibration is recommended at least every 12 months. Max/Min Display: Max/Min readings reached by the process are stored until reset by the user or until power to the meter is turned off. Password: Programmable password restricts modification of programmed settings. Non-Volatile Memory: All programmed settings are stored in non-volatile memory for a minimum of ten years if power is lost. Normal Mode Rejection: 64 dB at 50/60 Hz Operating Temperature: -40 to 75°C Storage Temperature: -40 to 75°C Relative Humidity: 0 to 90% non-condensing Connections: Removable screw terminals accept 12 to 22 AWG Tightening Torque: Screw terminal connectors: 4.5 lb-in (0.5 Nm) Enclosure: Explosion-proof cast aluminum with glass window, 0.30% max copper content, corrosion resistant powder coating, color: blue. NEMA 4X, IP68. Two ½" NPT threaded conduit openings. One ½" NPT nickel plated brass conduit plug with 10 mm hex key fitting installed. Mounting: May be mounted directly to conduit. Two mounting holes for 1.5" pipe or wall mounting. Weight: 40 oz (1.13 kg) Overall Dimensions: 4.30" x 4.27" x 3.62" (109 mm x 108 mm x 92 mm) (W x H x D) Warranty: 3 years parts & labor InputInput: 4-20 mAAccuracy: ±1 count Temperature Drift: 50 PPM/°C from -40 to 75°C ambient Decimal Point: User selectable decimal point Minimum Span: Input 1 & Input 2: 0.40 mA Maximum Voltage Drop: 1.7 VDC @ 20 mA; 4.9 VDC @ 20 mA with backlight option. Equivalent Resistance: 85 Ω@ 20 mA without backlight; 245 Ω @ 20 mA with backlight Loop-Powered Backlight Option: Factory installed only with field wiring option. Powered directly from the 4-20 mA loop, no batteries required.
