PD8-6300 Pulse Input Rate/Totalizer, Counter & Tachometer
Instruction Manual

Introduction
The ProtEX-MAX PD8-6300 is an explosion-proof,
pulse input flow rate/totalizer ideal for flow rate, total
and control applications. The meter 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 meter
is housed in a die-cast aluminum, field-mountable,
NEMA 4X/IP68 rated enclosure for convenient indoor
and outdoor installation.
The meter accepts a wide variety of pulse signals that
can be displayed as flow rate, total and grand total. In
fact, the ability to display flow rate and total at the
same time, or other combinations of rate, total and
grand total, is one of the most useful features of the
dual-line display.
The ProtEX-MAX is available in two configurations:
display only and fully loaded. Both versions include a
24 VDC power supply to power the flowmeter. A fully
loaded ProtEX-MAX PD8-6300-6H7 meter comes
with four SPDT relays, a 4-20 mA output, five digital
inputs and four digital outputs, and RS-485 serial
communications.
The four relays can be used for alarm indication or
process control purposes. 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.
One of the most useful applications for the PD8-6300
is to convert the pulse input from the flowmeter into
an isolated 4-20 mA output all the while displaying
flow rate and total on a big bright display as the
following graphic illustrates:

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.
