Introduction
Use these external expansion modules to add
functionality to ProVu meters in the eld. They can be
added at any time and are easy-to-install.
The PDA1004 relays module includes 4 Form A
(SPST) relays rated at 3 Amps and when added to a
meter that has 4 on-board relays results in a system
with 8 relays.
The PDA1011 dual 4-20 mA output module can only
be used with the dual input meters, Modbus scanners,
and the high voltage and current meters. Connecting
one of these modules to one of these meters that has
the on-board 4-20 mA output, results in a meter with
three 4-20 mA outputs.
The PDA1044 digital I/O module has four digital inputs
and four digital outputs per module and two may be connected
together to achieve a system with eight I/O. External digital
inputs function similarly to the F4 digital
input. They can be configured to trigger events
(i.e. acknowledge/reset alarms, reset total, reset max
and/or min values, disable/enable all relays, etc.),
provide specific menu access, or mimic front keys.
Digital outputs can be used to drive solid state relays,
or as inputs to other alarm or control devices
These expansion modules can be used individually
or in systems with other modules and serial adapters.
For instance, a system consisting of two 4-20 mA
inputs, three 4-20 mA outputs, eight relays, eight
digital inputs, eight digital outputs and RS-485 could
be congured using these items:

(1) PDA1004 Relays Module
(1) PDA1011 Dual 4-20 mA Out Module
(2) PDA1044 Digital I/O Module

these modules when they are connected to meters.

There is no need to remove the expansion module
from its case to complete the installation, wiring,
or setup of the unit. The expansion module may
be programmed using the meter’s buttons or via
MeterView Pro software.
•Connect the expansion module to the meter before
applying power to the meter.
•Do not connect or disconnect the expansion module
with the power on.
•Do not connect any equipment other than Precision
Digital’s expansion modules, cables, or meters to
the RJ45 MLINK connector. Otherwise damage will
occur to the equipment and the meter.
The relay, dual-analog output, and digital I/O
expansion modules PDA1004, PDA1011, and
PDA1044 are connected to the meter using a CAT5e
cable provided with each module (see Figure 1).
Figure 1. M-Link Connector Location on the Meter
The two RJ45 connectors on the expansion modules
are identical and interchangeable; one is used to
connect the meter to the module and the other is used
to connect the module to an additional module.
PDA1011 4-20 mA Output Conguration
The following must be performed prior to powering the
meter for the meter to recognize the PDA1011 dual
analog output module:
1.Connect the M-Link connector on the module to
the meter.
2.Wire and power each analog output being used.
Power should be provided by a DC supply
different than the one powering the meter.
PDA1004 Relays Connections
Connections are made to an eight-position removable
screw terminal connector.
Figure 3. External Relays Module Connections
PDA1011 Dual Analog Output Connections
Connections are made to a four-position removable
screw terminal connector.
Figure 4. Dual Analog Output Module Connections
PDA1044 Digital I/O Conguration
The jumper located between the RJ45 connectors of
the PDA1044 (see Figure 2) must be removed on the
second digital I/O module in order for the system to
recognize it as module #2.
Figure 2. PDA1044 Jumper Location
Terminal Block Connections
All connections are made to removable screw terminal
connectors located at the front of the module.
•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.
PDA1044 Digital I/O Connections
Connections are made to a ten-position removable
screw terminal connector.
Place the expansion module on a at surface with the
bottom surface facing up. The bottom surface can be
identied as the surface closest to the locking tab slot on the
modular connector as shown in Figure 6.

Figure 6. DIN Rail Clips Mounted to Expansion Module
Peel the protective layer off the adhesive tape on the bottom
of one of the mounting clips. With the hinge end of the clip,
as shown in Figure 7, facing the end of the module with the
communications connector, align the clip along the long
(side) edge of the module and centered lengthwise within the
at surface of the module as shown in Figure 8.
Hinge EndLatch End
Step 2: Mounting the DIN Rail to a Surface
The expansion modules, serial adapters and serial
converters weigh approximately 1.5 oz (42 grams) each so
the mounting hardware does not need to be overly strong.
We recommend two #10 pan head screws as shown in
Figure 10, but only because they best accommodate the
slots in the DIN rail. The amount of strain the wiring might
place on the module mounting needs to be considered also.
In many cases, DIN rail with double-sided tape might be
acceptable, although not recommended in areas of high
vibration or extreme hot or cold temperatures.
Figure 10. Mounting the DIN Rail with 2 #10 Pan Head
Screws
When choosing a location to mount the DIN rail, keep in mind
that wires will be entering both ends of the modules as shown
in Figure 11. Leave enough room on either end of module to
allow for wire routing to prevent undue stress placed on the
module’s connectors and mounting clips. The DIN rail may be
mounted on any vertical or horizontal mounting surface.
Figure 7. Hinge & Latch End of DIN Rail Clip
Figure 8. DIN Rail Clips Mounted to Module
Firmly press down on the clip for 10 seconds. Repeat this
procedure on the opposite side. Once the clips are properly
installed, the modules with clips mounted should look similar
to one or both of the modules pictured in Figure 9. While
the adhesive is initially quite strong, this strength improves
signicantly over a period of approximately 12 hours.
Figure 11. Example of Modules Mounted to DIN Rail
Step 3: Mounting Modules to the DIN Rail
To mount modules to a DIN rail, rst locate the approximate
desired position to place the module on the DIN rail, then
hook the hinge end of the mounting clip to the edge of the
DIN rail as shown in Figure 12. Next lower the opposite
“latch end” of the clip onto the rail. Press down on the
module until the latch end snaps in place.
