Signalling

Command and signalling devices 
To ensure that everything remains under control in the driver’s cab, we have developed long-lasting, maintenance-free and ergonomically improved LED display and lighting elements as well as acoustic signallers which have proven themselves time and time again in practice.

Special solutions for you too?
But of course!

 

 LED signal lamps

 

Leuchtmeldertableau 3x3 - Art.-Nr.716085

3x3 signal lamp unit - Part No. 716085

Messages and warnings are visualised in this 3x3 unit by means of energysaving, maintenance-free, surface-mount LED segments

A supply input for the LED elements, which is galvanically isolated from the control inputs, enables the luminous fields to be driven directly from an electronic controller

So coupling elements are not required

 

LED lighting elements

 

Beleuchtungselemente in LED Technik - Art.-Nr.716158Konsolenbeleuchtung in LED Technik - Art.-Nr.716164

Lighting elements in LED technology - Part No. 716158

These universal lighting elements enable long-lasting LED technology to replace high-maintenance tubular bulbs in numerous applications, such as lighting the working timetable, instruments and consoles

Several versions with variable mounting options are available for different installation locations around the driver’s desk

An IP67 version is also available for external use, e.g. for illuminating step treads

 

 

Console lighting in LED technology - Part No. 716164

LED console lighting enables the indirect illumination of larger areas, such as operator consoles on the lower section of the driver’s desk

The long-lasting LEDs can be driven in separate groups of 8 and the luminosity can be adapted to all conditions

Selecting the appropriate LED elements creates a pleasant colour quality and the anodised aluminium housing ensures that the illumination of the operator elements is glare-free

 

Lighting elements for round instruments

 

Beleuchtungselement für Rundinstrumente -

Lighting element for round instruments - Part No. 716090

Using this lighting element, round instruments with 60 mm diameter and lateral light strips can easily be fitted with long-lasting LED technology

Three LEDs on each side of the instrument ensure that the instruments are illuminated evenly and brightly for good legibility

Due to its compact design the lighting element is suitable for both new projects and upgrades.

 

Control units for exterior vehicle lighting

 

LSG3 - Art.-Nr.746200

LSG3 - Part No. 746200

Lamp control unit for controlling the external lighting on rail vehicles

Enables the most diverse range of signal patterns in the narrowest space

Direct connection of up to 49 lamps

Control and diagnostics via CANopen

Extensive lamp and module diagnostic functions

Voltage limitation (PWM) for maximum lamp operating life

Also suitable for LED lamps.

 

Dimmer modules

 

Dimmerbaustein - Art.-Nr.736021

Dimmer module - Part No. 736021

To ensure the driver’s cab has an ergonomic design, these modules make it easy to adjust the luminosity of the instrument lighting, signal lamps and halogen spots.

The modules are available in different versions to control incandescent lamps, halogen spots and LEDs and are suitable for voltages of DC 24 V and DC 110 V and output currents of up to 2 A.

The module is controlled through the connection of a potentiometer.

 

Buzzer modules

 

Summerbaustein für Bahnanwendungen - Art.-Nr.716149

Buzzer module for railway applications - Part No. 716149

This universal buzzer module is suitable for acoustic signalling in the most diverse applications

It can simply be attached to a top hat rail

16 different frequencies can be set via a DIP switch

The volume of the buzzer module can be reduced by fitting an additional resistor
