The DR9011 is an 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.

Three radio modules are available for the DR9011, 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 can transmit up to 20 miles. The 2.4GHz band version can transmit up to 10 miles.

The DR9011 provides isolation between input and power source. 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.

Screw terminal blocks that plug into the case allow easy wiring and removal of products. All of the DR Series of products provide transient protection to help eliminate damage from lightning and from other transients created on the power and signal leads.
