PD8-6262 ProtEx MAX Explosion-Proof Dual Analog Input Flow

Get a quote

The ProtEX-MAX™ PD8-6262 offers all the functionality of the ProVu PD6262 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It is specifically designed to display flow rate and total from two (2) analog output (4-20 mA, 0-5 V, 1-5 V, etc.) flowmeters. It displays these signals on a dual-line, 6-digit Sunbright sunlight readable display. The two display lines can be used to show both flow rates simultaneously, to alternate between the two inputs showing both the flow rate and total of each, or to show the result of math functions performed on the flow rates and totals. The total overflow feature allows up to 9-digit totals and grand totals to be displayed. The PD8-6262 includes a 24 VDC power supply to drive the flowmeter and can be equipped with up to four internal relays and a 4-20 mA analog output. It can be programmed and operated without opening the housing by using the built-in SafeTouch® through-glass buttons or the RS485 serial communication port with free Modbus® protocol.

Underrange Display flashes -99999
Display Assignment The Upper and Lower displays may be assigned to show: One or more rate channels: Channel A (Ch-A), B (Ch-B), or C (Ch-C), Toggle between rate channels: Ch-A & Ch-B, Ch-A & Ch-C, Ch-B & Ch-C, and Ch-A, Ch-B, & Ch-C, Total or grand total: Ch-A or Ch-B, Rate and total or grand total: Ch-A, Ch-B, Relay set points, Max and/or min values: Ch-A, Ch-B, or Ch-C, Toggle between any rate channel & units, Toggle between any rate/math channel & units, Total and units: Ch-A or Ch-B, Toggle between totals: Ch-A & Ch-B; Ch-A, Ch-B, and sum of Ch-A and Ch-B, Modbus input. The lower display may also be set to show engineering units or be off, with no display.
Programming Methods Four through-glass SafeTouch buttons, four mechanical buttons behind glass, digital inputs, PC and MeterView Pro software, or Modbus registers.
F4 Digital Input Contacts 3.3 VDC on contact. Connect normally open contacts across F4 to COM.
Max/Min Display Max/min readings reached by the process are stored until reset by the user or until power to the meter is cycled.
Password Three programmable passwords restrict modification of programmed settings and two prevent resetting the totals. Pass 1: Allows use of function keys and digital inputs, Pass 2: Allows use of function keys, digital inputs and editing set/reset points, Pass 3: Restricts all programming, function keys, and digital inputs. Total: Prevents resetting the total manually Gtotal: Prevents resetting the grand total manually.
