Components for railway applications (2. strana)

rail transport l automation ComatReleco electrical switching elements d 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 d 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 d 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 d 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 d 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. Conclusion d Turck's product portfolio is really very extensive, but Turck is now also a supplier of complete system solutions.
