DR9011-03

RTD INPUT POINT-TO-POINT TRANSMITTER

DESCRIPTION

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

SPECIFICATIONS

FEATURES

• Direct RTD Input

• Four Digital Inputs For Contact
Closure or NPN Transistor

• DIN Rail Mount - Steel Clip

• 10-30VDC Power

• Reverse Polarity Screw-On
SMA Antenna Connector

• 915MHz ISM* Band - 2
Versions, 14 Hop Sequences

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.

• 2.4GHz Unlicensed Band - 1
Version, 7 Hop Sequences

• Spread Spectrum, Frequency
Hopping Technology*

• Line of Sight Range to 20 Miles
With 915MHz Band Radio

• Line of Sight Range to 10 Miles
With 2.4GHz Band Radio

• 5 Year Warranty
(1 Year on Radio Module)

• UL/cUL Recognized

The DR9011 provides isolation between
input and power source.

The product provides lead wire
compensation for a 3 wire RTD.

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.
