PD6830X ProtEX-MFI Explosion-Proof Modbus Scanner

Brand: Precision Digital Corporation

Precision Digital ProtEX Modbus Scanner, PD6830X

The explosion-proof ProtEX-MS2 and ProtEX-MFI Super Snoopers are serial input RS-485 Modbus® RTU scanners. These Modbus devices are ideal for hazardous areas or safe areas in need of a rugged solution.

The PD6830X carries major approvals including:

  • CSA Certified as Explosion-Proof / Dust Ignition-Proof / Flame-Proof
  • ATEX and IECEx Certified as Flame-Proof and Protection by Enclosure

The ProtEX-MS2 has a two-line decimal display. The ProtEX-MFI top line displays level in feet and inches up to 399 ft, 11 and 15/16 inches. It includes a 20 segment tank level indicator.

Each scanner can accept up to 16 Modbus process variables (PVs), from up to 16 devices. The scanners automatically cycle through the PVs, with the ability to manually cycle PVs or pause scanning.

Up to four math channels (CV1-CV4) may be used to perform math functions on any of the input variables. Math functions include sum, difference, weighted average, ratio and more. Nested math functions may be used in these math equations, allowing for complex math functions.

The display is programmable to show any input, math channel, units, or tags, on a variety of display combinations between the top and bottom displays.

Standard features include SafeTouch through-glass buttons for operating the scanner without removing the cover, a backlight that makes the display mode visible in any lighting condition, 511 points of input data logging, and two open collector pulse or alarm outputs. A 4-20 mA output is available as an option.

The enclosure is provided with three threaded conduit holes and integrated pipe or wall mounting flanges. One conduit plug is installed, and included in the explosion-proof approvals.

Free, PC-based, ScanView EX software that connects to the scanner via the PDA8068, PDA7485-I, or the PDA8485-I is available for programming and setup of the instrument.

The instrument can also be programmed using the four SafeTouch through-glass buttons, without removing the cover, or with four internal push-buttons.

The PD6830X includes on-board data logging of up to 511 points.
