Point-to-point, wireless I/O modules for remote locations

| By Chemical Engineering


With a rugged NEMA 4X/IP68 industrial housing, the new VWB2000 signal-wire replacement system (photo) is a point-to-point wireless signal bridge that 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 ft 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 input/output (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. Each unit has both inputs and outputs for bi-directional communication. — Acromag, Wixom, Mich.
