Earth leakage monitoring relays DEA71 and DEB71
Carlo Gavazzi has launched the DEA71 and DEB71 range of earth
leakage monitoring relays, used to detect earth leakage current
which can be potentially dangerous when undetected in electrical
networks. These devices ensure the protection of installations
against fire, and people against electrocution by interrupting
the mains on a faulty load when used with a CTG core balance
transformer.
The setpoint on the DEA71 is factory set to 30mA or 300mA and
it is not adjustable speeding up installation time, sets a reliable
tripping level and protects against tampering whilst the DEB71
is fully adjustable and is available from 30mA to 5A or 300mA to
30A. Both devices are equipped with two changeover relay outputs
providing the alarm signal and an additional warning output. One
output triggers at 60% of setpoint value providing an early warning
to the user, the other output is used to shut down the supply to
prevent electrocution or fire.
Each of the DEA71 and the DEB71 have a supply voltage from 24
to 240Vac, local and remote test/reset function in case of tripping
or for regular test and both can be used on three phase or single
phase, which not necessarily needs to be earthed.
Lenovo reveals
intelligent solutions
Lenovo has announced a series of new
products, partnerships and solutions
designed for business customers that
demonstrate the company’s ongoing
Intelligent Transformation strategy.
The strategy reflects Lenovo’s business
perspective on how to build end-to-
end solutions with smart features that
transform businesses and improve the user
experience.
Intelligent Transformation will
reinvent and restructure entire systems
of production, management, and
governance worldwide. It’s driven by
emerging technologies, including artificial
intelligence, augmented reality, the
Internet of Things, blockchain and 5G
connectivity.
Yang Yuanqing, CEO, Lenovo, said:
“Today, we share industry-leading
partnership and product announcements,
reinforcing our dedication to realising
the great potential of Intelligent
Transformation. Lenovo is a business ready
for the future, and we are a partner helping
to drive intelligent transformation with
companies globally, every single day.” n
The DEA71 and DEB71 can be the perfect solution for building
automation including industrial, commercial and residential, data
centres, materials handling, water treatment, doors and entrance
applications or anywhere where people could be at the risk of
electrocution and equipment could be at risk of fire. n
South Ayrshire school pilots cutting
edge LiFi technology
Next-generation high-speed wireless Internet using light technology has been
installed in a Scottish secondary school to enhance the learning environment. This
makes the school pupils the first in the world to benefit from cutting edge high-
speed wireless Internet connectivity – using light.
The project is being conducted in conjunction with The University of Edinburgh
and is being overseen by Scottish Futures Trust, which supports the Scottish
Government’s Digital Strategy. The Scottish Government also supported the
pilot with a £16,000 grant through its Digital Schools initiative for equipment
and installation. pureLiFi and the LiFi Research and Development Centre at the
University of Edinburgh provided resources for the execution of the pilot with
hands-on support and subsequent testing.
South Ayrshire Council’s Kyle Academy is the first school globally to pilot real
LiFi technology within the classroom, which is the next generation of wireless
communications technology. The installation of pureLiFi’s LiFi-XC system
comprises eight LiFi-enabled LED light bulbs in the ceiling and students have been
given access to LiFi-XC Stations that plug into their laptops enabling high-speed
connectivity through the lights.
LiFi technology, which was born out of Professor Haas’ 16 years of research
in light communication, and further developed by pureLiFi, is a high-speed, bi-
directional, secure and fully networked wireless communication that uses light
rather than radio waves used in Wi-Fi, to transmit data. By using light waves, LiFi
offers unprecedented bandwidth, which significantly enhances the connectivity of
the classroom to enhance the learning environment. n
