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.
Features
  • Signal Wire Replacement in a Rugged, Industrial Housing
  • Inputs and Outputs on Both Field Units
  • Simple to Order, Configure, & Install
  • 1 Mile Line-of-Sight Outdoor, 500 Ft Indoor Range
  • Inputs: Analog (4-20 mA, 0-10 V, 0-5 V, 1-5 V), Digital, and RS-485 Modbus Communications
  • Outputs: Analog (4-20 mA), Digital, and RS-485 Modbus® Communications
  • Remote or Attached Antenna
  • Repeaters and Directional Antennas Available
  • Flanges for Wall or Pipe Mounting
  • Software Available for Even Easier Setup
  • NEMA 4X, IP68 Enclosure
