Point-to-point wireless I/O modules replicate signals at remote locations
Instrumentation from Acromag takes analogue, discrete or Modbus signals at one location and reproduces them at a second one, said the company, introducing the VWB2000 signal wire replacement systems as part of its Vertu range.
The VWB2000 signal wire replacement system is in a rugged NEMA 4X/IP68 industrial housing. 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 provides signal strength and other diagnostic information.
A VWB2000 wireless I/O bridge is easy to set up and install. Each unit has one analogue I/O channel, four discrete I/O and Modbus communications that are field-configurable in minutes using the pushbutton controls, said Acromag. Free Windows software simplifies configuration on a PC via USB and enables advanced features such as encryption and analogue signal calibration. The weathertight 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.
The wireless I/O bridge is an interface signals from Point A to Point B where it is not practical to run long wires or conduit. Each unit has both inputs and outputs for bi-directional communication. Analogue inputs accept 4.0 to 20mA, 0 to 5V, 0 to 10V, or 1.0 to 5.0V signals. Analogue output is 4.0 to 20mA. Digital I/O channels support
0 to 5.0V TTL logic levels. Modbus RTU serial communication is EIA-485 compatible.
Acromag has been developing and manufacturing measurement and control products for more than 60 years. They offer a complete line of industrial I/O products including process instruments, signal conditioning equipment, data acquisition boards, distributed I/O systems and communication devices.
