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.
