Point-to-Multipoint Wireless System

Model: WR-90-TR

The WR-90-TR is a point to-multipoint wireless bridge that eliminates the need for running wiring, saving time, and reducing installation costs. These units are used with the WR-90-BA base station which can be configured for a variety of inputs and outputs. The WR-90-TR accepts analog, discrete, and Modbus® inputs and wirelessly broadcasts them to the WR-90-BA base station. The WR-30-RP wireless repeater can be added if signals need to be routed around line-of-sight obstructions. This system configuration offers a highly flexible means of getting data from level sensors mounted on silos up to a mile away to a control room. 

  • Transmitting data from level sensors to a control room without running wiring
  • Complex operations where obstructions exist, and the signal must be routed using a wireless repeater
  • Operations where data needs to be centralized from one or more bins, tanks, or silos
  • Locations where bins, tanks, and silos are distanced up to 1 mile from a control room
  • Point-to-multipoint signal wire replacement
  • Simple to configure using WR Manager programming software and onboard USB
  • Range of 1-mile line-of-sight, 500 ft. indoors
  • Analog, digital, and RS-485 inputs and outputs
  • Remote or attached, directional and omnidirectional antenna options
  • Units housed in IP68, NEMA 4X enclosure
  • Flanges for wall or pipe mounting
