Designed to fit all freight locomotive and transit vehicle applications, the various models are housed within an IP65 sealed enclosure. Easy front-panel customization allows new variant versions to be quickly created to match existing legacy cabling and connectors. Drop-in replacement units are backward-compatible with legacy Quantum event recorders for easy retrofitting. 

• Optional integrated 32 GB crashworthy memory, expandable to 256 GB
• Interfaces for discrete and networked data collection from on-board systems
• Option for storage of digitized video data with integrated CMM
• Configurable integrated alerter function allows implementation of any user-defined Vigilance Alerter System algorithms
• Optional MVB bus interface

The Siemens alerter system controller is a locomotive engineer reset timer which ensures that the locomotive crew is attentive to the operation of the locomotive at all times.

• If no engineer-initiated activity is detected within a speed-dependent time limit, the alerter provides visual and audible signals to the crew – if there is still no response, it initiates a penalty brake application.
• Under normal operating conditions, the alerter does not interfere with standard activities since it is reset whenever the crew operates any of a number of commonly-used controls.

• Analog indicator for light and heavy rail
• Used for the analog indication of measured quantities based on voltage, current, or frequency changes
• Available with several input parameters, an additional sub counter, and sub indicators
• Optional counter can be used for input pulses
• Mature products with varied functions and configurations
• Available in a square or round design

Various speed indicator models are available for use in freight locomotives. They can be easily retrofitted into existing installations.

• Direct replacement for existing speed indicators
• Power-up display of all user selectable settings
• Dual display – one display facing the engineer, one display facing the conductor's normal position
• Odometer – true net distance based on the direction of the locomotive
• Alerter light/horn option – interface to existing alertness devices
• Axle drive compatibility – operates from any number of end-of-axle electronic axle drives and accepts industry standard 20 and 60 pulses-per-revolution inputs
• Dimmer control – four-position dimmer control for ease of reading in any ambient lighting condition

Our axle generators use internal speed sensors to count pulses related to specific gear rotations. Speed data is relayed to the on-board computer to determine potential overspeed conditions. Axle generators with up to three magnetic reluctance-type speed sensors are available – the first two driven from a 60-tooth gear and the remaining sensor from a 40-tooth gear. For details of all the configurations available, please contact your Siemens Technical Assistance for Rail Automation Team.

The universal interface panel is a self-contained, microprocessor-controlled device which translates input signals from traction motor speed sensors to wheel rotation frequencies. It is designed to replace existing assemblies with solid state sensors by physically locating the sensors inside the locomotive. Using the Universal Interface Panel results in increased mechanical reliability.

• Enclosed in an aluminum extruded shell
• 5 input select lines to automatically program outputs
• User selectable 1 to 500 pulses-per-revolution output

The dynamic brake monitor is used in locomotives equipped with an integrated locomotive computer. It provides the engineer with total accumulated braking or tractive effort data as well as the ability to monitor braking or tractive effort. It also enables the improvement of train handling and braking performance.
