Secure and easy to implement at FA sites.
Stable operation even in harsh FA environments!
Signal status can be observed!
The Wireless LAN Unit has the same level of noise and
environmental resistance as OMRON FA Devices, such as
PLCs and Power Supply Units. It is capable of stable
operation when installed within the same control panel as
other FA devices.
There is no need to reset
the power supply even
if the Wireless LAN
Unit runs out of
control because it
will automatically
restart itself.
With the popular Received Signal Strength
Indicator (RSSI), the status of invisible
radio waves can be easily identified by
checking the indicators.
● Received Signal Strength Level
Good noise resistance
can be obtained by
connecting the Wireless
Unit to an OMRON
Power Supply Unit.

Versatile and easy installation!
OMRON'S original security system prevents important
production information from being disclosed.
This Wireless LAN Unit can be easily
installed anywhere on a DIN Rail or
a wall.
Install it in the
control panel with
other FA devices!
Use magnets to mount
it on metal surfaces!
The latest encryption technology combined with OMRON'S
original encryption technology forms a strong security
environment.
