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.

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.

Power Connections
Power connections are made to a two-terminal connector labeled
POWER on Figure 7. The meter will operate regardless of DC polarity
connection. The + and - symbols are only a suggested wiring convention.

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.).
