Introduction

The Helios PD2-6100 is a multi-purpose, easy to use, large-display digital strain gauge & load cell meter

ideal for weighing and force measurement applications. With a max current of 350 mA at 10 V, it can

support up to twelve (12) 350 Ω load cells (minimum load resistance of 28 Ω), making it ideal for

multipoint weight measurement applications. It also 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 mV input signals up to 300 mV. Three of the front panel buttons can be custom-

programmed for a specific operation. The mV input can be scaled to display the process in two different

scales; for example, pounds on the upper display and gallons on the lower display.
A fully loaded Helios PD2-6100 meter comes with four (4) SPDT relays, a 4 20 mA output, one 10 VDC

sensor excitation, one 24 VDC power supplies, five (5) digital inputs and four (4) digital outputs, and

onboard RS485 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.
