Charging solutions.

Mobile Device Charging.

The EAO Charging solutions improve the passenger experience, by providing phone charging, eliminating ‘low battery anxiety’ and enabling passengers to stay connected on their journeys.

With the seatback mounted SliderFLEX that holds the phone securely in either landscape or portrait mode and a table top mounted version, every seat can be provided with a charging service.

The innovative charging solution utilises a novel multi-coil inductive charger certified to the global Qi standard for iOS and Android that can charge any enabled phone wherever it’s charging interface is located – just by placing it in the SliderFLEX seatback holder, or on the table charging pad.

Wireless charging eliminates the need for cables and improves the reliability of the system, whilst the optional USB socket caters for older phones, or allows passengers to charge two devices simultaneously.

Key features

  • Seatback mounted, or embedded tabletop charging units
  • Wireless charging with Qi Inductive Technology
  • Additional USB socket to charge two devices, or for charging older phones
  • Can be retrofitted to seats and tables during refurbishment
  • Rugged, reliable design for rail, tram and bus applications

The Smart Box is mounted without special tools, by simply snapping it onto the mounting adapter. Thanks to the M12 connection, the Smart Box is operational in an instant. You also have the option of mounting the device directly on a standard DIN rail without the mounting adapter – this gives you flexibility in terms of the number and arrangement of Smart Boxes. The Bus connection or direct wiring alows for easy system integration.

Compatible actuators and indicators from EAO

The Smart Box works best with EAO’s fully compatible Series 84 indicators, illuminated push buttons and Emergency Stop switches. Further switching options are avialable on request. The robust design, combined with front protection up to IP67 enables reliable switching at temperatures from -25 °C to +70 °C (depending on the integrated products), in dirty or damp conditions, or in the event of vibration.

Individual front design with films

You have the option of adapting the front design for almost any application using a polyester film (e.g. for a customer logo or warning sign), a labelling plate, or an LED status display. If needed, EAO will integrate additional electronics functions onto a PCB or will equip and wire the Smart Box entirely in line with your preferences.

Advantages

  • Easy snap-on mounting and M12 connection technology
  • Multiple boxes can be flexibly mounted in series; robust and compact design
  • Easy system integration thanks to Bus connection or direct wiring

Multi-Legend Alarm Indicator.

Flexible, bright and reliable.

Multi-Legend Alarm Indicator (HMIS)

When an alert is raised, it is important to know exactly why: the multi-legend alarm indicator for driver’s cabs simplifies fault monitoring with its modular HMI, enabling enhanced safety within train applications.

Flexible, modular design

You can individually define the size of the operator panel, the symbols and the LED colours. The flexible number and arrangement of symbols and low back panel depth of less than 8 mm make it ideal for driver’s cabs and applications with limited space for display elements. 

Typical applications

  • Rail vehicles
  • Industry
  • Utility and special vehicles

Refined technology

For maximum safety in operation, any alarm display must be electrically independent; this also includes redundant illumination in every element. You control the display system via a Bus interface, digital inputs/outputs, CAN or other interfaces. You can easily and effectively integrate it into existing systems, and the display modules are available with dimmable illumination. The light test function with capacitive touch sensor in the alarm indicator is effective and responds immediately.

The wide selection of display symbols, grid spacing and symbols for each module make this status monitoring system even more flexible. If you would like to do so, you can mount the display panel using adapters or directly with mounting studs.

The multi-legend alarm indicator complies with EN 45545 and offers connection options for up to 36 symbols per module in a voltage range of 24 VDC to 110 VDC.

Advantages

  • Adaptable control unit size and symbols
  • Rapid adaptation to customer-specific requirements
  • Additional functions can be integrated
  • Ultra-thin design (< 8 mm), suitable for control units on driver’s cabs
  • Bright, even illumination, visible in all light conditions
