Extending the Surecross wireless systems by repeating transmissions in 3 km hops to a multi-hop total of 20 km or more, the DX80DR radios from Banner Engineering can be linked to transmit data up to 20 km. They can be used to connect a wide variety of field devices directly, including PLC’s, Controllers, HMI’s, DCS’s, transmitters, level, pressure and temperature sensors. Multiple units can be placed to allow signals to pass over hills and other obstacles that would block a single wireless hop. The data radio allows extension of the widely used Modbus communication protocol to many applications where wiring is impractical because of distance or accessibility. It can also be connected with digital, analog or temperature signals using other wireless products from the company. The large wireless networks enabled by the new radio provide previously unavailable information to users in a wide range of industries. Using the data radio, clusters can be combined and connected to create systems with 2400 wireless points, covering over 100 km2. For even larger systems, multiple wireless networks can co-exist in the same physical area without interference. The radios are configured for rapid, easy connection to all remote and central control elements in a network. They can be powered by 10-30 VDC, battery or solar power supply, allowing wireless repeaters to be placed where no power is available.
