Description
The WDRXL-24-420MA Wireless Analog Transmitter/Receiver System allows for
remotely monitoring or controlling equipment from a distance up to
1 mile away using license free wireless 2.4GHz 802.15.4 communication.
Each set features one 4-20mA analog signal input and output.
Both the transmitter and receiver are also equipped with one
contact closure input that is used to control an
open-collector output on the opposing unit for additional control or alarm functionality

Transmitter Operation
|
Transmitter Operation
The wireless 4-20mA analog signal transmitter reads analog
input data from temperature, pressure, strain, flow, level or RH
sensors and then sends the measured data over the air to a remote location.
The measured 4-20mA current signals are converted
to digital packets and then transmitted via a license free radio
transmission to a waiting control receiver. The transmitter also
includes one dry-contact switch input that controls one open collector
output on the opposing control receiver.
|
|
Receiever Operation
|
Transmitter Operation
The wireless 4-20mA analog receiver decodes any incoming
radio packets and converts them back into the same 4-20mA current signal that is being measured by the transmitter
in real time. The control receiver also includes one
dry-contact switch input that controls one open collector
output on the opposing transmitter.
