Point-to-Point Wireless Bridge

Model: WR-30-TR

The WR-30-TR point to-point wireless bridge saves money and time by eliminating the need for running long spans of wire. It transmits data at distances up to one-mile line-of-site outdoors or 500 feet indoors. The WR-30 is used in pairs, with a primary unit taking an analog, discrete, or Modbus® input signal and broadcasting it to a secondary WR-30 unit. The secondary unit can also send data back to the primary unit. The WR-30-TR arrives ready for power in a rugged, weather-tight housing. Antennas are attached to the unit or can be remotely located. Optional repeaters can be added if signal range needs to be extended or signals need to be routed around obstructions.
