Description

The WXL420-ME-900 Wireless Analog Transmitter/Receiver System allows for remotely monitoring or controlling equipment from a distance up to 6 miles away using license free wireless radio communication. Each set features one 4-20mA analog signal input and output. Each system is sold as a factory programmed matched set. That means there is no field settings needed to operate right out of the box.

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.

Receiver 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.
