PDW30 Point-to-Point Wireless Bridge
Brand: Precision Digital Corporation
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 starts with an Analog, discrete, or Modbus® input and wirelessly broadcasts it to a second PDW30 unit. The second unit then recreates that signal at its location.
Just put the units in the field anywhere you have 12-24 Vdc power.
