Helios PD2-6262 Dual Analog Input Rate/Totalizer
Instruction Manual
6
Introduction
The Helios PD2-6262 is a multi-purpose, easy to use,
large-display dual-input rate/totalizer ideal for flow
rate, total, and flow control applications. It features
large 1.8 inch superluminous sunlight-readable LED
digits, which can be read from up to 100 feet 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 current and voltage signals
(e.g. 4-20 mA, 0-10 V) from an analog 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, 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 Helios PD2-6262 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
Helios an excellent addition to any system.
