PD8-6262 Explosion-Proof Dual Analog Input Flow Rate/Totalizer
Instruction Manual
7
Introduction
The ProtEX-MAX PD8-6262 is an explosion-proof
dual-input rate/totalizer ideal for flow rate, total, and
flow control applications. The totalizer features a
dual-line display, with a main display 0.60" (15 mm)
high, and a second display of 0.46" (12 mm) high
superluminous LED digits, which can be read in any
lighting condition, including direct sunlight. The
totalizer is housed in a die-cast aluminum,
field-mountable, NEMA 4X/IP68 rated enclosure for
convenient indoor and outdoor installation.
The meter accepts two inputs; either can be current or
voltage signals (e.g. 4-20 mA, 0-10 V) from analog
output flowmeters. The rates, as measured by the
flowmeters, are automatically aggregated into
cumulative totals and grand totals which can be
displayed with the rates.
Various math functions may be applied to the rate,
total, and grand total of the two channels, including
addition, difference, absolute difference, average,
weighted average, multiplication, division, minimum,
maximum, draw, ratio, and concentration. This is in
addition to the input signal conditioning functions
(linear, square root, programmable exponent, or
round horizontal tank calculations).
The displays, relays, and the analog output may be
assigned to the rate, total, or grand total of input
channels A or B, or math result channel C. Three of
the programming buttons can be set for custom
operation.
A fully loaded ProtEX-MAX PD8-6262 dual-input
rate/totalizer comes with four SPDT relays, a 4-20 mA
output, two 24 VDC power supplies, five digital inputs
and four digital outputs, and RS-485 serial
communications. The four relays can be used for
alarm indication or process control applications. The
4-20 mA isolated output, Modbus RTU serial
communications, and digital I/O features make the
ProtEX-MAX an excellent addition to any system.

SafeTouch Buttons
To make it possible to program and operate the
ProtEX-MAX in a hazardous area, the programming
buttons that are located behind the glass window can
be operated without removing the cover by using the
SafeTouch through-glass buttons. The operator puts
their finger on the glass over the button and the
button is actuated.
