The PD663 is a loop-powered field meter that is FM Approved and CSA Certified as Explosion-Proof, Dust-Ignition Proof, and Flame-Proof, and ATEX & IECEx Certified as Flame-Proof and Protection by Enclosure. The PD663 is easy to install and program and it can be seen in a variety of lighting conditions and even in bright sunlight. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines into a hazardous area. The meter gets all of the power it needs from the 4-20 mA loop and its 1.7 V drop results in a minimal burden on the loop. The meter features a wide -40 to 75°C operating temperature range and comes with two 1/2" NPT threaded conduit openings and flanges for wall or pipe mounting. Calibration is a quick process involving the four internal push buttons. The PD663’s display will read up to 2999; we call this 3½+ digits!

Input

Input: 4-20 mA
Accuracy: ±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; 4.7 VDC @ 20 mA with backlight option.
Equivalent Resistance: 85 Ω @ 20mA without backlight; 245 Ω @ 20mA with backlight
Loop-Powered Backlight Option: Factory installed only. Powered directly from the 4-20 mA loop, no batteries required. Backlight can be enabled or disabled via alternative wiring of terminal block. The display brightness will increase as the input signal current increases.
HART Transparency: Analog input will not interfere with existing HART communications on the wired 4-20 mA signal
