It’s worth exploring…
Adding RTA to your total control solution.
So you have either built or taken delivery of a new control
panel. Now it’s time to integrate it to your equipment on
the oor. You have looked for and discovered that not all
devices are able to move the data from your equipment
to your programmable controller. In this case, you prob-
ably have a Micro Logix, Compact Logix, or Control Logix
processor in your control scheme. What do you do?
This is the point where it is worth considering a solu-
tion from Real Time Automation (RTA). RTA provides
a processor involving the fastest and easiest system
to move raw TCP data to Rockwell Automation Logix
devices. These Gateway Devices, like the 490NBS and
the 490NBX, optimize moving data from devices like bar
code readers, printers, weigh scale devices, etc. to and
from RM Logix Controllers.
A single module has the ability to network multiple TCP
devices and move data simultaneously, all the while me-
thodically independent. This is accomplished with no host
messages and little to no latency. There is no software to
download or code to write, which makes RTA one of the
quickest and most cost effective solutions to integrate
networks. Using your Internet browser to congure and
transfer your data, an included discovery tool allows you
to congure through your web browser interface. It’s that
simple. Nothing more.
RTA manufactures its products in
the United States with ample stock
at Kendall Electric to take care of
your data solutions.
It’s worth exploring … RTA as part
of your total control solution.

We all know that occupancy sensors detect the
presence or absence of people in a space to au-
tomatically turn on or off area lighting. It is also
pretty obvious when the wrong type of sensor is
used because either the lights don’t come on or
turn off when they are needed.
For energy savings reasons, new levels of complexity and regulations
continue to roll out. The options can get overwhelming, but one of
the newer terms to consider is a vacancy sensor.
A vacancy sensor requires an individual to manually turn on the
lights. It could be the same physical device as an occupancy sensor,
but it does not automatically turn on the lights like an occupancy sen-
sor does. Think of the times you grabbed that last paper you forgot
off your desk or when you used your hospital restroom in the middle
of the night. You did not need a fully lit room and would never turn on
the lights on your own. Utilizing a vacancy sensor allows that option.
Both technologies turn off when motion is no longer detected for a
specied period of time.
The Leviton Decora Wall Switch Sensor with LED NightLight #OSSNL
is a neat product that can be programmed as either an occupancy
or vacancy sensor allowing for automatic-on or manual-on. Product
highlights include:
• Installation – replaces single-pole wall switch in a standard wall box
• Guide light – when you need a small amount of illumination
• Nightlight mode – dims automatically to 5% of full brightness after 2
minutes of no occupancy
• Energy savings - consumes less than ½ watt
• Adjustable time delay - settings of 30 seconds to 2 hours
• Use in smaller rooms - restrooms, ofces, storage areas, laundry
rooms, lounges
Take a look at this sensor and give it a try. It is currently in stock at
Kendall Electric.
