Helios PD2-6400 High Voltage & High Current Meter
Instruction Manual
6
Introduction
The Helios PD2-6400 is a multi-purpose, easy to use,
large-display high voltage and current input meter
ideal for measuring direct voltage and current or the
output from voltage shunts and current transformers.
It features large 1.8 inch superluminous 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 has one 0-300 VAC or VDC voltage input
and one 0-5 AAC or ADC current input. It may be
used with a single voltage or current input, or to
measure both simultaneously. A math channel P
calculates apparent power as the product of the
voltage and current inputs.
The Helios PD2-6400 can display voltage, current,
and apparent power. The dual line display can display
any two parameters simultaneously, or can alternate
between any parameters as well as their
programmable units and tags.
A fully loaded Helios PD2-6400 meter 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.
