Introduction
The Helios PD2-6300 is a multi-purpose, easy to use, large-display pulse input rate/totalizer
ideal for flow rate, total, and control applications. 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 meter
accepts pulse (e.g. 40 mVp-p to 8 Vp-p), 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 rate, as
measured by the flowmeter, is automatically aggregated into a cumulative total and grand total
which can be displayed simultaneously with the rate. Three of the programming buttons can be
set for custom operation.
A fully loaded Helios PD2-6300 meter comes with four (4) SPDT relays, a 4 20 mA output, two
24 VDC power supplies, five (5) digital inputs and four (4) digital outputs, and RS485 serial
communications. The two or 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.
