Helios PD2-6363 Dual Pulse Input Rate/Totalizer
Instruction Manual
6
Introduction
The Helios PD2-6363 is a multi-purpose, easy to use,
large-display dual pulse input rate/totalizer ideal for
flow rate, total, and flow control applications.
It features
large 1.8 inch superluminous LED digits, which can be read
in direct sunlight from up to 100 feet (30 meters) away. It is
housed in a water-resistant, field-mountable NEMA 4X/IP65
rated enclosure for convenient indoor and outdoor
installation
.
The programming buttons are located behind the
lower panel door and are not generally accessible
during operation. For that reason, we recommend the
use of the PDA2364-MRUE remote control station
which has four buttons to mimic the buttons behind
the panel.
The meter accepts two pulse (e.g. ±40 mV to ±8 V),
square wave (0-5 V, 0-12 V, or 0-24 V), open
collector, NPN, PNP, TTL or switch contact signals
from a pulse output flowmeter. 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, or grand totals 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 Helios PD2-6363 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 Helios an excellent addition to any
system.
