PDW30 Point-to-Point Wireless Bridge Instruction Manual

 

 


 
 

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 it

’s 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 antennae are also offered.
