Acromag broadened its Vertu brand of 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 prepaired transmitter/receiver units that have a range of 1 mile outside or 500 feet indoors in 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 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 directly mount to supporting conduit or pipes and walls.
Each unit has 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.
