INTRODUCTION:

The iO-WR-XR wireless relay transceiver uses
state-of-the-art radio technology to transmit
any dry contact on/off signal to another factory-
paired transceiver up to 1/2 mile through
obstructions, such as conventional building
materials. Each transceiver can be powered by
12 or 24 Volts AC or DC. Range verification
testing can also be accomplished by powering
each transceiver using a 12 volt battery pack.
Successful transmission and reception is
indicated on transmit and receive LEDs located
on each transceiver.

APPLICATION USE:

The iO-WR-XR can be used in a wide range of
applications where running wire is difficult, or
existing wires have been cut or damaged. The
iO-WR-XR can be used to control HVAC
equipment, fans, pumps, lighting and industrial
equipment.

closure on a relay output of the other
transceiver.
