Description

The Wilkerson Instruments DR9051R wireless signal transmitter is a polling RF transmitter that will accept both analog and switch contact inputs. A 12 bit A/D converter is used to digitize the analog data. Analog data and switch status is read when requested by the companion DR9050 Control Unit. The DR9050 polls the DR9051R wireless signal transmitter and outputs the data in Modbus RTU format. A single DR9050 can poll up to 247 DR9051R's utilizing a single Hop sequence.

The DR9051R wireless signal transmitter from Wilkerson Instruments has a repeater capability that is useful for data monitoring in areas where the DR9050 cannot communicate directly with a DR9051R due to distance or obstructions in the transmission path. The switch inputs require a standard contact closure or an open collector NPN transistor.

Three radio modules are available for the Wilkerson Instruments DR9051R wireless signal transmitter, two 915MHz band versions with 7 hop sequences each, and a 2.4GHz band version with 7 Hop sequences. They use spread spectrum, frequency hopping technology. These choices provide 21 different Hop sequences that allow 21 systems to work in the same locale without interfering with each other.

With proper antenna and cable selection and a 915MHz band version radio, the DR9051R wireless signal transmitter can transmit up to 20 miles. The 2.4GHz band version can transmit up to 10 miles. The DR9051R provides isolation between input and power source. The DC inputs are individually isolated. This isolation makes the DR9051R wireless signal transmitter useful for measuring input signals with high common mode voltages and for breaking ground connections to eliminate ground loops.

There are three types of inputs available to the Wilkerson DR9051R wireless signal transmitter - dual DC, bridge, and RTD. Please refer to the data sheets for further information.
