INTRODUCTION

The PROVU

PD6100 is a multipurpose, easy to use 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  load cells (minimum load resistance of 28 ),

making it ideal for multipoint weight measurement applications. It 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.

The basic model includes an isolated 5 or 10VDC Sensor power supply that can be used

to power the input Sensor or 24 VDC for other devices. An additional isolated 24 VDC

power supply is included with the 4-20 mA output option. A digital input is standard.

A fully loaded PD6100 meter has the following: four SPDT relays, 4-20 mA output, one

10 VDC sensor excitation, and one 24 VDC power supply. The PD6100 capabilities may

be enhanced by adding the following external expansion modules: four SPST relays –

creating an eight-relay process meter, two digital I/O modules with four inputs and four

outputs each, and USB, RS-232 or RS-485 communication adapters.

The eight relays can be used for alarm indication or process control, such as pump

alternation control. The 4-20 mA isolated output, Modbus RTU serial communications,

and digital I/O options make the PD6100 an excellent addition to any system.

Model PD6100 Strain Gauge/Load Cell Meter Instruction Manual

SAFETY INFORMATION

CAUTION: Read complete

instructions prior to installation

and operation of the meter.

WARNING: Risk of electric

shock or personal injury.

WARNING!

Hazardous voltages exist within enclosure.

Installation and service should be

performed only by trained service

personnel.

INSTALLATION

There is no need to remove the meter from its case to complete the

installation, wiring, and setup of the meter for most applications.

Instructions are provided for setting up a 12/24 VDC powered meter to

operate from 12 VDC and for changing the Sensor power supply to

output 5 or 10 VDC instead of 24 VDC, see page 17 and 18.

Unpacking

Remove the meter from box. Inspect the packaging and contents for

damage. Report damages, if any, to the carrier.

If any part is missing or the meter malfunctions, please contact your

supplier or the factory for assistance.

Panel Mounting Instructions

• Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm x

45 mm). Refer to Figure below, for more details.

• Clearance: allow at least 6.0" (152 mm) behind the panel for wiring.

• Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).

Recommended minimum panel thickness to maintain Type 4X

rating: 0.06" (1.5 mm) steel panel, 0.16" (4.1 mm) plastic panel.

• Remove the two mounting brackets provided with the meter (back-off the two

screws so that there is ¼" (6.4 mm) or less through the bracket. Slide the

bracket toward the front of the case and remove).

• Insert meter into the panel cutout.

• Install mounting brackets and tighten the screws against the panel. To

achieve a proper seal, tighten the mounting bracket screws evenly until

meter is snug to the panel along its short side. DO NOT OVER TIGHTEN,

as the rear of the panel may be damaged.

Refer to the following pages for panel mounting diagrams.

Configuration for 12 or 24 VDC Input Power Option

Warning!

Do not exceed voltage rating of the selected

configuration.

Meters equipped with the 12/24 VDC power option are shipped

from the factory ready to operate from 24 VDC.

To configure the meter for 12 VDC power:

1. Remove all the connectors.

2. Unscrew the back cover.

3. Slide the back cover about 1 inch.

4. Configure the J9 jumper, located behind the power

connector, for 12 V as shown below.

Sensor Excitation Voltage Selection (EX+, EX-)

All meters, including models equipped with the 12/24 VDC power

option, are shipped from the factory configured to provide 10 VDC

excitation for the sensor.

If the sensor requires 5 VDC excitation, the internal jumper J3 must

be configured accordingly.

To access the voltage selection jumper:

1. Remove all the wiring connectors.

2. Unscrew the back cover.

3. Slide out the back cover by about 1 ½ inches.

4. Configure the J3 jumper, located behind the input signal

connector, for the desired excitation voltage as shown.

Caution!

Do not use 24V to power a strain gauge bridge.

The 24 V jumper configuration should only be

used for mV input applications.

Connections

All connections are made to removable screw terminal connectors

located at the rear of the meter.

Caution!

Use copper wire with 60°C or 60/75°C insulation for all line

voltage connections. Observe all safety regulations.

Electrical wiring should be performed in accordance with all

applicable national, state, and local codes to prevent

damage to the meter and ensure personnel safety.

Connectors Labeling

The connectors’ label, affixed to the meter, shows the location of all

connectors available with requested configuration.

Warning!

Do not connect any equipment other than Precision

Digital’s expansion modules, cables, or meters to the

RJ45 M-LINK connector. Otherwise damage will occur

to the equipment and the meter.

Signal Connections

Signal connections are made to a six-terminal connector labeled

SIGNAL on Figure 7. The EX- (negative excitation) terminal is used to

sense the sensor excitation voltage for ratiometric operation, when the

sensor is powered externally.

Switch Configuration

Setup and programming is performed both through the front panel buttons

and switch settings shown below. The switch configuration must

correspond to the setup and programming starting on page 29 (same

range, type, etc.).

Excitation (Switch 1)

The excitation switch designates whether the meter will use its internal

power supply or an external power supply.
