Technical Specifications

RailsterTech SpecsApplication
Power Supply15 – 110 VDC
110 – 220 VAC
Both the VDC and VAC inputs are fuse and inversion protected.
Universal power supply can fit any train without additionnal converters.
ArchitectureARM9 – Linux OSLow-power, reliable embedded hardware based on Kerlink’s technology
Internal batteryRechargeable, up to one year autonomy.Continuous performance with intermittent train power. Measurements of position, fuel level, main battery volatge while asset is parked & power-off
Power consumption5W – 25WThe power input can be limited 5W by way of software parameterisation in case limited power is available on the train auxiliary power supply.
CommunicationGPRS, Wifi, Ethernet, USBGPRS with tunneling capability (maintains active session and enables lower sim card costs). Robust M2M messaging from our partner Kerlink.
Wifi for download of large files while in the workshop area.
Ethernet enables to connect to component such as Faiveley’s Atess, Alstom’s traintracer, etc.
GPSSiRFstarIII, 20 channelsLow power,  Position accuracy < 2.5 m, Hot fix < 1 sec. cold fix < 35 sec., warm < 15 sec. Can be placed inside driver’s cabing behind windshields.
Local storage16GoData can be stored locally before being downloaded via Wifi. This enables remote logging of large volumes of data.
OTA firmware upgradeOver-the-air software upgrade (OTA) capabilityEnable to add features or customise embedded alerts to the desired functionnality on installed devices, without physical access to the device. This saves on update and maintenance costs
Internal sensorsVibration detection, temperature, external powerEnables to trigger wake-up based on movement, power, etc.
Accelerometer ExternalAccelerometer is glued to the body of the component to be monitored.
Extension cards40-pin Deutsch connector precabled with up to 3 internal extension card slotsThe Railnova extension cards system offers a wide choice of hardware specific mini-cards that connect to sub-components and sensors. See extension cards connectivity details for more information
