Wireless I/O
WI-I/O 9 Multi I/O Units
Atransceiverisawirelessdevicemade
upofatransmitterandreceiver.Since
eachmodulecanmanagebothinputand
outputsignals,itcanbeusedtomonitor
transducers and control industrial
processes.Thismodulecanalsobeused
as a repeater to relay another wireless
device’stransmission,thusincreasing
theoverallrangeofthesystem.
