Acromag broadened their new Vertu brand of innovative instrumentation with the release of the VWB2000 signal wire replacement system in a rugged NEMA 4X/IP68 industrial housing.

This point-to-point wireless signal bridge takes analog, discrete, or Modbus signals at one location and reproduces them at a second location. The system consists of two pre-paired transmitter/receiver units that have a range of one mile outside or 500 feet indoors at industrial environments. This range can be extended using wireless repeater units or high-gain directional antennae. An LCD display provides signal strength and other diagnostic information.

A VWB2000 wireless I/O bridge is easy to set up and install. Each unit has one analog I/O channel, four discrete I/O and Modbus communications that are field-configurable in minutes using the push-button controls. Free Windows software simplifies configuration on a PC via USB and enables advanced features such as encryption and analog signal calibration. The weather-tight enclosure is cast aluminum with a glass window and a corrosion-resistant powder coating for field mounting. Units can mount directly to a supporting conduit or securely to pipes and walls.

“This wireless I/O bridge provides a very effective solution to interface signals from Point A to Point B where it is not practical to run long wires or conduit,” says Robert Greenfield, Acromag’s business development manager.

Each unit has both inputs and outputs for bi-directional communication. Analog inputs accept
4-20mA, 0-5V, 0-10V, or 1-5V signals. Analog output is 4-20mA. Digital I/O channels support
0-5V TTL logic levels. Modbus RTU serial communication is EIA-485 compatible.
