Introduction
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 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
or the
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.
