VWB2000 Vertu® Series Wireless Signal Bridge Description

The Acromag Vertu® VWB2000 wireless I/O system provides a simple solution to reproduce an analog, discrete, or Modbus® signal at a remote location. This point-to-point wireless bridge is enclosed in a rugged, weather-tight housing to meet the demands of industrial installations.

Acromag’s wireless bridge system is very easy to set up and quite reliable for your application. The system consists of two pre-paired transmitter/receiver units. You can connect analog, discrete, or Modbus® inputs to one unit and wirelessly broadcast signal data to the other unit. The receiving unit recreates the original signal for output to local instrumentation. Install the units in the factory or field – anywhere you have 12-28V DC power.

Each wireless unit has one analog I/O channel, four discrete digital I/O channels, and RS-485 Modbus communication. If the primary unit’s channel is an input, the secondary unit’s corresponding channel is an output and vice-versa. Analog voltage input will be converted to a proportional current output.

VWB2000 wireless transceivers are housed in a rugged, IP68, NEMA 4X painted aluminum enclosure. They are a smart, cost-effective solution for interfacing I/O signals across long distances in a harsh industrial environment. Eliminate the expense and hassles of hard wiring your instrumentation throughout your facility or across a field.

This wireless bridge system has a range of 500 ft. indoors at industrial environments and an outside line-of-sight range of 1 mile. Check the installation guide and manual for tips to avoid problems and optimize performance. Certain factors, such as physical obstacles and improper placement, can reduce transmission distances.

The VWB2000 signal bridge is designed for fast and easy setup with just a few pushes of the front panel buttons. Using Acromag’s free VWB Config software enables more advanced capabilities when connecting a PC to the unit’s USB port. Advanced settings include encryption and analog signal calibration.
