In new constructions, it is absolutely
essential to achieve maximum energy
efficiency and to avoid situations where
a load (a fan, a light or a heating system)
is supplied in an unused area. This is
also the goal of building automation
systems: for this reason Carlo Gavazzi
offers its energy management products
connected to the Dupline
®
field- and
installation-bus, together with the
home automation system as a unique
control solution capable of transmitting
multiple digital and analog signals
over long distances via the Dupline
®
2-wire bus. The home automation
controller connects to Carlo Gavazzi
energy meters via Modbus RS485, and
Dupline
®
pulse count input modules are
also available as a general solution
for interfacing to meters measuring
consumption of energy, water, gas,
heat etc.
However, it is a completely different
situation when dealing with old
buildings which are completely
lacking in building automation or in
monitoring systems. In this case the
best and cheapest solution is retrofitting
the various switch gears with the
implementation of an energy measuring
system, specifically developed, such as
the EM2172R and EM2172V “Retrofit”
versions. By using these energy meters,
it is possible to obtain the current
measurement simply by installing the
split-core current sensors (included
in EM2172R) onto the wires, without
disconnecting them or switching off the
mains. The meter can be mounted in any
type of panel frames, being extremely
compact and suitable both for panel
mounting (72x72 mm) and for DIN-rail
mounting (only 4-DIN modules).
This is possible by means of the
patented detachable display, utilising
transponder technology.
When several loads are to be controlled,
the new EM270 and EM271 energy
meters provide a complete monitoring
solution, which is very compact and
easily installed, saving 90% of the
installation time when compared to a
traditional monitoring system.
