Carlo Gavazzi offers energy management solutions which provide a Site 1 Site 2 Site 3 Site 4 Site 4
transparent view of your organisation’s energy consumption with accurate RS485 Zone 1 Zone 2
measurements and monitoring of your energy usage. Web Server
The VMU-C and VMU-Y energy platforms have proved to be significant Gateway Level Up to 100
solutions when you need to manage and integrate data from either single Sites with
or multiple sites to ensure maximum energy efficiency. The VMU-C EM RS485 Em² Server
gathers the data from up to 32 energy meters, power analysers and VMU
Series I/O modules on a single installation for viewing on any PC. Acting Meter Up to 100
as a gateway to other self-contained solutions, many companies find it Level Sites with
easier and financially more viable to commit to a single capital VMU-Y
expenditure, eliminating ongoing hosting costs. The VMU-Y allows the
user to aggregate information from up to 10 VMU-C EM units within a Up to 32
single centralised interface. This effectively allows you to monitor up to Energy
320 meters and access the information from any PC using a standard Meters &
web browser. 10 VMU-M
Our unrivalled family of easy to install DIN rail/panel mount single and for each
three phase energy meters meet all the latest requirements of the VMU-C
Measuring Instruments Directive (MID) and resolve the issues with
monitoring energy usage laid out in part L2 of the Building Regulations. RS485
The range starts from an ultra-compact DIN-rail mounted, single phase
32A energy meter, providing both active and reactive energy metering Distributed I/O Modules Local I/O Modules I/O
and cost allocation functions, up to a three phase energy analyser offering I/O and Tº Inputs and Tº Inputs
built-in hot/cold water, gas and remote heating measurements and load
monitoring. Main Meter
Touch screen technology is now available on all our meters which makes
standard user operations such as page scrolling, programming and RS485
parameter checks not only simpler, but faster; as well as being easy to
read, avoiding any mechanical issues normally associated with using Management Mobile Phone Email
traditional keypads. Level
EM21-72V is designed specifically for retro-fit applications. Current Main DDC
measurements can be carried out by means of the external miniature Controller (HVAC Controller)
split core current sensor which restricts the voltage to the meter to 0.333V, Dali Master
making it a favourable solution for the installer. BACnet / Ethernet / IP Dali Ballast

Reduce Cost of HVAC Install with Dupline® BACnet / Ethernet / IP

Dupline® offers a realistic alternative to traditional parallel wiring by Automation I/O
allowing field devices to be connected together on a simple 2 wire Level BACnet Objects
bus network. Reducing the installation cost by as much as 50%
makes it a very competitive solution for your larger BMS applications. RS485 Dupline® PIR / LUX

As well as saving on the install cost, the design and commissioning EM24
process becomes much simpler because of the implementation of a 2
wire bus. The bus itself allows free topology and the use of any cable, Field Level Input / Pulse Counter CO2 / T / %RH
for example unshielded cable can be used without fear of difficulties. 0-10 V out Temperature Control
A wide range of field devices are available for picking up signals in the Relay
field including temperature, humidity and CO2 together with relay and Light Switch
analogue output modules.
Dupline® is the ultimate remote I/O for your BMS controller. You can
implement the strategy in the BMS controller in the same way as you do
now, but all the points from the field are presented to you as BACnet
objects from the Dupline®/BACnet gateway. Applications for Dupline® are
generally where the I/O points are distributed over a wide area and are
of low density. HVAC, under floor heating, natural ventilation and alarm
point monitoring are good examples, but there are also opportunities for
reducing costs within lighting control and energy monitoring and control.
The SB2WEB Dupline® Controller can manage up to 7 Dupline® networks
each managing more than 400 data points. In addition to this, up to 32
energy meters can be connected via Modbus. Energy meter variables
are also presented to the BMS system as BACnet objects.
A DALI Gateway is now available for the Dupline® system making it
possible to offer lighting control and/or integration with HVAC
applications.
The Dupline® network is flexible, modular and fully expandable and
requires no special cable. A standard unshielded 16 AWG cable can be
used up to 3 miles long without repeaters. Bus and power cables can be
run next to each other without fear of interference. The system can easily
be expanded by simply adding the required modules on to the bus,
therefore last minute changes are easily accommodated. The SB2WEB
BACnet Controller makes it freely compatible with new and existing
building automation systems and eliminates the need for expensive home
runs, saving you money on wiring and installation costs against traditional
device to DDC solutions.
