Introduction
The Precision Digital PDW30 gives you a simple, straightforward way to get an analog, discrete,
or Modbus® signal from where you have it to where you need it. It’s a point-to-point wireless
bridge packaged in a rugged, weather tight housing designed to meet the demands of industrial
installations.
The PDW30 is simple to order, simple to configure, and easy to trust with your application.
Guaranteed ranges assure it will work with your application, or you can send it back - no ques-
tions asked. A wireless survey tool is available for those who may require a site survey for
longer distances, making it easy to verify the installation will work the first time.
The PDW30 takes an analog, discrete, or Modbus® input and wirelessly broadcasts it to a sec-
ond PDW30 unit. The secondary unit then recreates that signal at its location. The secondary
unit may also transmit its own analog, discrete, or Modbus signals back to the primary unit. Just
put the units in the field anywhere you have a signal and power.
A wide range of accessories, including mounting kits, antenna-related accessories, and repeat-
ers, are available. The antenna may be directly attached or remotely located. High gain direc-
tional antennas are also offered.

Pre-Installed Conduit Plug
The PDW30 is supplied with one pre-installed optional conduit plug for installations that do not require the
use of both conduit entries. The conduit plug includes an internal hexagonal socket recess for removal.
Mounting Instructions
The PDW30 has two mounting holes that may be used for a 1.5” pipe mounting or wall mounting. Alterna-
tively, the unit may be supported by the conduit using the conduit holes provided. The antenna is
threaded into one of the three conduit holes and may be moved as appropriate for the installation.
It can also be mounted by using the PDA6963 mounting bracket in order to orient the device antenna
away from the pipe. Refer to Mounting Dimensions on page 29 for details on wall or panel space require-
ments.
Cover Jam Screw
The cover jam screw should be properly installed once the wireless units have been wired and tested in a
safe environment. The cover jam screw is intended to prevent the removal of the units’ cover while in op-
eration without the use of tools. Using a M2 hex wrench, turn the screw clockwise until the screw contacts
the unit. Turn the screw an additional 1/4 to 1/2 turn to secure the cover.
Caution: Excess torque may damage the threads and/or wrench.
FCC Notice
Contains FCC ID: MCQ-XB900HP
The enclosed device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (i.) this device may not cause harmful interference and (ii.) this device must accept any inter-
ference received, including interference that may cause undesired operation.
IMPORTANT
The RF module has been certified for remote and base radio applications. If the module will be used for
portable applications, the device must undergo SAR testing. This equipment has been tested and found
to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be deter-
mined by turning the equipment off and on, the user is encouraged to try to correct the interference by
one or more of the following measures: Re-orient or relocate the receiving antenna, Increase the separa-
tion between the equipment and receiver. Connect equipment and receiver to outlets on different circuits,
or consult the dealer or an experienced radio/TV technician for help.
Canada (IC) Notice
Contains Model: XB900HP, IC: 1846A-XB900HP
Integrator is responsible for its product to comply with IC ICES-003 & FCC Part 15, Sub. B - Unintentional
Radiators. ICES-003 is the same as FCC Part 15 Sub. B and Industry Canada accepts FCC test report or

Connections
To access the connectors, remove the enclosure cover and unscrew the two captive stainless steel
screws. Remove the electronics assembly from the enclosure. Signal connections are made to removable
terminal blocks on the back of the electronics assembly. Grounding connections are made to the two
ground screws provided on the base – one internal and one external.
• Static electricity can damage sensitive components.
• Observe safe handling precautions for static-sensitive com-
ponents.
• Use proper grounding procedures/codes.
Warning!
• Observe all safety regulations. Electrical wiring should be per-
formed in accordance with all agency requirements and appli-
cable national, state, and local codes to prevent damage to
the device and ensure personnel safety.
Figure 1 below shows the locations of screw terminal blocks on the rear of the wireless unit assembly.

Power Connector
Power connections are made to a two-terminal connector
labeled POWER in Figure 1. The PDW30 is reverse polarity
protected; it will not be damaged if wired backward.
Make sure that the power supply can provide between
12 and 28 VDC to the wireless device.
Power PDW30 and 2-Wire Transmitter from Same Power Supply
The PDW30 wireless units may be powered from the same power supply that powers the 2-wire (loop-
powered) transmitter, assuming that the supply provides enough voltage for both units. To power both de-
vices from the same supply, wire the devices to the supply as shown below.

Signal Connector
The analog input may be either 4-20 mA, 0-10 V, 0-5 V, or
1-5 V. The appropriate input type must be programmed for
each unit.
Once the appropriate input type has been programmed, wire
the analog signal source to the device as shown in the dia-
gram at right.
The analog input will not interfere with any existing HART sig-
nal on a 4-20 mA current loop. However, the HART signal will
not be transmitted wirelessly.
4-20 mA Output Connector
The 4-20 mA output corresponds with the analog input signal
on the paired wireless device. The analog output signal is al-
ways 4-20 mA, regardless of the input type on the other wire-
less module.
For instance, if the analog input type on the first device was
0-10 V and the input value was 5 V, the second device would
output 12 mA.
Connect the mA OUT terminals to a device scaled to read a
4-20 mA signal.
The analog output is internally powered; no external power
supply is required.
