Wireless analog and switch data acquisition products from Wilkerson Instrument offer Modbus RTU-protocol with 1 to 247 remote units and line-of-sight ranges to 20 miles. DR9050 control unit interfaces to a standard Modbus RTU RS485 network, allowing a Modbus controller to access the remote units. DR9051 remote unit is available with dual 4-20 mA inputs, RTD input, or strain gauge input. It also has 4 discrete inputs for monitoring switch status. Strain gauge input provides 10-V excitation for 4 bridges in parallel. RF connection can be 900 MHz or 2.4 GHz. Both RF systems use spread spectrum frequency hopping technology to allow multiple systems in close proximity. www.wici.com Wilkerson Instrument Co. Inc.
