Our product experts are here to help you find the right solution for your application!

The Precision Digital PDW90 Base Station is the starting piece to a rugged, customizable, point-to-multipoint wireless bridge. It offers a highly-flexible means of getting an analog, digital, or Modbus® signal from where you have it to where you need it. Modular input/output cards and expandable field units, available for the base station, and mean that the PDW90 can be customized to meet the needs of any wireless application.

The PDW90 is simple to order, simple to configure, and easy to trust with your application. A wireless survey tool is available for those installations that require a site survey for longer distances, making it easy to verify the setup will work the first time.

Field units accept analog, discrete, or Modbus® inputs and wirelessly broadcast it to the PDW90 base station. The base station can recreate these signals with its onboard RS-485 or analog and digital I/O cards. It can also be programmed to activate relays or output analog/digital signals to the field units. Just put the field units wherever there are process signals and the base station in the control room.

Fixed or remote antenna modules as well as a wide range of accessories are available, including mounting kits, antenna-related accessories, and repeaters. The antenna may be directly attached or remotely located. High gain directional antennae are also offered.
