Introduction
The Helios PD2-6310 is a multi-purpose, easy to use, large-display pulse input batch controller
ideal for simplifying independent batch control operations where local control is preferred to
expensive plant operation systems. It features large 1.8 inch superluminous LED digits, which
can be read in sunlight 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 controller comes programmed for easy start, pause, stop, and batch size (preset) changes.
Display line two (2) can be programmed to display rate, grand total, batch count, or preset by
cycling the Stop (F3) button. Digital inputs come standard.
Single and multi-stage batching is possible with up to four (4) on-board relays. Each batch
control relay may have a unique preclose amount when used for multi-stage batching. Manual
start batching is default, but automatic batching with a restart after a programmed time delay
from the completion of the last batch is also possible.
Overrun correction adjusts the closing of the batch control relays to adjust for inaccuracies from
batch to batch. This increases accuracy over time as systems wear out. The overrun correction
feature is capable of compensating for inaccuracies of up to 10% of the programmed preset
value.
The controller accepts 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. Three of the programming buttons can
be set for custom operation. A fully loaded PD2-6310 batch controller 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, making it an excellent addition to any system.
