TUNNEL SAFETY
The YardControl Cabinet is an integral part of the Lighting and Power
Supply systems of the railway tunnels. Its main function is to manage
power supply at 1000V of the gallery.
The Front-End cabinet control is the brain of the Lighting and Power Supply
systems for railway tunnels. Inside there is a redundant server that carries
out all the safety functions, monitor and SCADA Lights and Power Supply
system diagnostics, and a SOFTPLC able to interact with all the control
cabinets of KVM console to guarantee vital functions.
The Segment Control Cabinet is an integral part of the Lighting and Power
Supply systems of the railway tunnels. Its system main function is the
management of the emergency lighting via Powerline O.C.

PANTOGRAPH VIDEO INSPECTION SYSTEMS TVCC SYSTEMS FOR LEVEL CROSSING
The System addresses the problem of individuation automatic and preventive
diagnosis of pantographs failures. A lesion on the creeping material of the
pantograph can compromise its functionality, or it can to be a symptom of an
incipient major damage entity; for this it is appropriate not only to acquire the
most information on the pantograph but also be able to process them
properly.
The Level Crossing video system allows to control the regular closing
barriers and checking for the absence of obstacles in the shared area
between railway and asphalt road. The Level Crossing video system is
designed to monitor from 1 to N PL sites.

SITE
CONVERTERS ALONG THE RAILWAY LINE
The converter of the 3kVDC/400VAC 3F+N series are meant
to be used in railway tracks and directly connected to the
high voltage line and mounted on a pole. It’s not requested
a hornet circuit breaker for the connection to the
converter line. The output is400VAC 3 phase with neutral,
the maximum power is 50kW.
APPLICATIONS
Toit can be connected devices of the De-Icing System,
of the RED System, of the PL Systems and other types of utilities.

The Building, therefore office, industry, common area, etc. will be covered by a suite of smart services,
scalable & modulare solutions, able to provide for each building or plant a suitable answer for a best
management in terms of energy & maintenance. Thanks to a «open architecture» is possible to integrate with
a sw connector (on server on directly to the hw concentrator omn the field) others systems without any
cabling or a lot of hours of installations. Via powerline or with a wireless system the building will become
smart without adding cost.
