The Wilkerson Instruments DR9011 wireless signal transmitter is an point-to-point 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 then transmitted to the companion DR9021 Receiver where the analog signal and switch status is reconstructed. The switch inputs require a standard contact closure or an open collector NPN transistor.

Wilkerson Instruments DR9011 wireless signal transmitters are available in three models depending upon input type. The DR9011-01 wireless signal transmitter accepts dual DC input. The DC Inputs are individually isolated. This isolation makes the product useful for measuring input signals with high common mode voltages and for breaking ground connections to eliminate ground loops. The DR9011-02 wireless signal transmitter accepts bridge input. A 10 VDC precision power supply is built-in and provides excitation for up to four (4) 330 ohm bridges. The DR9011-03 wireless signal transmitter accepts RTD input. This model provides lead wire compensation for a 3 wire RTD.

Three radio modules are available for the Wilkerson Instruments DR9011 wireless signal transmitters, 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. A DIP Switch on the PC board is used to set the Hop sequence. With proper antenna and cable selection and a 915MHz band version radio, the DR9011 wireless signal transmitter can transmit up to 20 miles. The 2.4GHz band version can transmit up to 10 miles.

The DR9011 wireless signal transmitter from Wilkerson provides isolation between input and power source. Screw terminal blocks that plug into the case allow easy wiring and removal of products.
