ComatReleco electrical

switching elements

Electric lights and other appliances must

be properly switched and controlled

(On/Off). Whether used in high-speed

trains, trams, metros, cable cars or other

rail vehicles, but also switchboards in tunnels, bridges, train stations, ships, etc.,

components are always expected to last

a long time in demanding conditions.

Mainly for this equipment, ComatReleco

manufactures a wide range of relays

and other components for switching

common appliances

and LED lights, or

monitoring voltage

or current levels.

They have been developed in accordance with the European

railway

standard EN 50155.

These are mainly relays for switching currents up to 16 A (depending on the type up to 800 A), contactors up to 25 A, monitoring relays, and

a wide range of electromechanical or semiconductor time relays for various, even

non-standard, voltage levels. These products meet all related railway standards

and norms, including DIN EN 45545 (fire

protection of railway vehicles).

Inductive and optical sensors

Inductive sensors are probably the most

common automation elements, but the

standard design is not sufficient for many

applications. This is why Turck has developed and manufactures special types that

can withstand demanding conditions such

as high vibrations, temperatures, pressures, temperature changes, splashes of salts

or cleaning agents, etc. Therefore, monitoring of the status/position of various

metal parts of the device can be solved in

an easy and reliable way. In addition,

Turck uprox+ inductive sensors provide

a large switching distance that is the same

for all types of metals, a precise switching

point, and fast response.

Optical sensors and safety light curtains

are ideal for monitoring the door areas

of transport vehicles during exiting and

boarding, providing timely and especially

safe automatic door control. They can also be used for the permanent monitoring

and detection of the designated delimited

transport area, or for counting passengers.

Pressure sensors

One of the most frequently measured quantities is pressure. This is used in hydraulic

or cooling circuits, closed tanks, or tank

containers. Turck also offers a wide range

of pressure sensor solutions for vehicle

equipment. Even though there is a large

number of different

process connections

and output signals,

and a large selection

of pressure ranges,

an optimal sensor can

be found for any application. With the intelligent functions of

IO-Link, the PS510

and PS310 lines are

perfectly prepared

for the needs of

precise automatic

control. The new

compact pressure

transmitters of the PT1000 line meet the

conditions of common industrial applications, as well as the heavy duty conditions

of railway applications (e.g. on brake systems) and are therefore a very interesting

alternative to the types used so far.

Turck offers the Vilant RFID system, which

can monitor the condition of rolling stock

through a network of RFID detectors installed at selected locations near the track,

company entrances, workshops, car washes, consignment depots, and individual

stations, or even in depots with mobile readers. The solution includes delivery from

individual RFID chips to software with

connection to the ERP system of the user

or owner. Full use of data registered by

the fault detection system enables preventive maintenance to increase safety and

operational efficiency. In this area, the

GEN2 UHF RFID technology and the robust Vilant Railroad units have proven

to be successful. This makes the work of

the train operator in assigning various maintenance and service tasks much faster

and much more precise.

The RFID monitoring of rolling stock in

real time as it passes through a reading

gate also enables the accurate monitoring

Connecting

and interconnecting cabling

Quality and durable cabling is the basis of

any reliable electrical and bus bar system.

This is why Turck offers a wide range of individual connector cables, cable harnesses, and separate connectors. For vehicle

applications, Turck manufactures cables

with the connection technology DT – Deutsch connectors and TSS – Superseal

connectors which are specially adapted to

the specific requirements of vehicles. By

using silicone seals providing IP67 and

IP69K protection, connections are protected against the high pressure or steam cleaning which is usually done on vehicles.

RFID systems for efficient fleet

management

To ensure more efficient registration of

each wagon, their maintenance and repair,

and meeting transport and safety needs,

and identification of traffic. RFID also allows the creation of a database and the

sharing of data with operators who own

trains or their freight, and the precise identification of all wagons and locomotives.

More efficient management can therefore

increase the use of cars. It also results

in an increase in the performance of customer services, streamlining internal processes in general, as is evidenced by successfully implemented applications such

as the metro in Helsinki, the Finnish Transport Agency, and VR Group.
