SKU: PD6870-0K0 Product Type: Large Display Meter Input: Current (4-20 mA) Power: Loop-Powered Approvals: ATEX (FP), CE, CSA (XP), FM (XP), IEC (FP) Display Category: LCD, Single Line, Large Display Display: 1.0″ High, 3 1/2 Digits LCD Warranty: 3 years Backlight: Standard Product Series: ProtEX Product Family: PD6870 Product Category: Loop Powered Meters, Explosion-Proof, Field Mounted Indicators Product Application: Level, Pressure, Process, Hazardous Area
The ProtEX FarVu PD6870 is an explosion-proof, loop-powered process meter with 1″ display digits in a field-mountable enclosure designed for demanding applications in hazardous areas or in the harshest environmental conditions. The meter derives all of its power from the 4-20 mA loop with a small 1 V drop so there is no need to run additional, costly power lines into a hazardous area. Like all ProtEX products, the PD6870 loop-powered indicator carries FM, CSA, ATEX, and IECEx approvals for use in hazardous areas. It is programmed using four easy-to-access, front-mounted control dials.

Input: 4-20 mA Accuracy: ±0.1% of full span ±1 count Temperature Drift: 150 PPM/°C from -40 to 75°C ambient Decimal Point: User selectable decimal point Calibration Range: 4 mA input: -1000 to +1000; 20 mA between 20 and 2000 counts greater than 4 mA display. Two point linear display span. Maximum Voltage Drop: 1 VDC @ 20 mA without backlight; 4 VDC @ 20mA with loop-powered backlight Input Overload: Over current protection to 2 A max. HART Transparency: Analog input will not interfere with existing HART communications on the wired 4-20 mA signal 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.
