DESCRIPTION
When the transmitter has a dual channel
input, the DR9021 has a 4/20 mA output for
each channel. If the transmitter has a single
channel analog input, the DR9021 provides
two 4/20 mA outputs proportional to the single
input.
Switch outputs are provided as discrete
Open Collector NPN transistors. A DIP
Switch on the PC board allows selection of
Normal Acting or Reverse Acting (Failsafe)
outputs.
Three radio modules are available for the
DR9021, 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 hopping sequence.
With proper antenna and cable selection and
a 915MHz band version radio, the DR9021
can receive from a DR9011 up to 20 miles
away.
The DR9021 provides isolation between the
output and the power source.
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.
