Acromag VWB2000 point-to-point wireless I/O modules

The Acromag VWB2000 signal wire replacement system 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 comes in a rugged NEMA 4X/IP68 industrial housing and comprises two pre-paired transmitter/receiver units that have a range of 1.6 km outside or 152.4 m indoors in industrial environments. This range can be extended using wireless repeater units or high-gain directional antennas. An LCD display provides signal strength and other diagnostic information.

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-compatible 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 aluminium 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.

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