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 line of sight.
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.

HOW IT WORKS:
Each iO-WR-XR transceiver has 2 switched
input relays and 2 relay outputs. A closure on a
relay input of one transceiver will result in a
closure on a relay output of the other
transceiver.
