    New Series 09 Rugged CAN Keypads.

    Date: January 12, 2020 11:00 PM

    For rugged applications in heavy duty and special vehicles.

    Olten, Switzerland, August 2019 – High reliability and functional safety are crucial to controlling safety-related applications in vehicles and machines – whether in construction equipment and vehicles, agricultural equipment or in special and commercial vehicles of various types. Harsh environments and low back panel depth require a robust and compact product design. The actuators and indicators must also be precisely configured, both mechanically and electronically, to suit the respective application. The new high-quality Rugged CAN Keypad and Rugged CAN Rotary Cursor Controller from Series 09 meet these requirements with cutting-edge system integration.

    Typical applications
    • Roadmaking vehicles and roller compactors
    • Loaders, dozers and excavators
    • Cranes, dump trucks and crawler drills
    • Fire-fighting and rescue vehicles
    • Road sweepers, cleaning vehicles and refuse trucks
    • Snow removers and groomers
    • Agricultural vehicles and equipment

    Robust, innovative design – Robust and innovative construction is a feature of the Rugged CAN Keypads design. The up to IP67 protected actuators and indicators work reliably at operating temperatures from – 40 °C to + 85 °C. The low back panel depth and robust clip-in or screw-in mounting allows for easy, flexible installation, either vertically or horizontally. These high-quality devices also offer excellent tactile feedback, and are clearly visible in daylight and at night thanks to the powerful RGB LED halo and LED symbol illumination. Attractive and configurable 4-segment halo button illumination is integrated as standard. The customisable illumination provides the operator with excellent visual feedback, and is combined with a unique, contemporary design. Legends can be selected from our extensive library of industry-recognised, laser etched ISO 7000 symbols or customer supplied graphics to meet end user specific needs.

    • Individual 4-segment and RGB halo ring illumination
    • Designed for functional safety*: ISO 26262 and ISO 13849
    • Intelligent HMIs with CAN bus integration
    • Robust, innovative, ergonomic design sealed up to IP67 protection
    • Interchangeable ISO 7000 range of symbols or customised symbols

    Functional safety* and CAN bus integration – The Rugged CAN Keypads feature high reliability and are designed for functional safety in accordance with the EN ISO 13849 PLD and ISO 26262 ASIL B standards. Put simply, functional safety means that the system monitors whether the safety-related function is working properly. If a function error occurs, the system promptly informs the operator. Thanks to the CAN bus integration, the devices are intelligently and easily integrated into a CAN system – the devices are fitted with a Deutsch DT Series connector.
    More than an expert. A partner of the automotive industry. As a global partner to major automotive manufacturers and suppliers, we provide our customers with high-quality, products, design capabilities and services.

    New HMIS Multi-Legend Alarm Indicator – Flexible, bright and reliable.

    Date: January 12, 2020 11:00 PM

    Simplifies fault monitoring contributing to increased safety within railway applications.

    Olten, Switzerland, November 2019 - Train drivers need to easily see an overview of the current status or critical situations requiring their attention - whatever the cab lighting conditions and independent of   the rest of the electrical systems. EAO offers a highly reliable, customisable and quick to engineer solution that meets the driver's needs and with the possibility to add additional functionality such as a dimmable illumination.

    With its extremely flexible and modular design, the HMIS Multi-Legend Alarm Indicator fulfils a broad range of application needs. The panel size and the symbols are customisable. Different illumination colours are available. The flexible number and arrangement of the symbols as well as the ultra-thin mounting depth of less than 8 mm thickness ideally fit to driver desk and control cabinets, as well as in other railway application where the space envelope for the status indicators is limited.

    • Customisable panel size and symbols
    • Quick adaption to customer-specific requirements
    • Additional functionality can be added
    • Ultra-thin design (< 8 mm) to fit in driver desk panels
    • Bright even illumination visible in all light conditions

    Every alarm indicator is electrically independent to guarantee high operational safety, redundant illumination on each element provides increased reliability. The complete system of indicators is controllable by bus interface, digital IO or other interfaces, which allows easy and effective integration with existing systems. In addition, the indicator modules can be provided with dimmable illumination. The lamp test functionality is effective and immediate with a capacitive touch sensor included in the alarm panel. With a range of different indicator tile dimension, grid spacings, and numbers of tiles per module this is a truly flexible status monitoring system. Mounting of the indicator panel can be adapted to the customer needs with adapters or directly with mounting studs.

    The Multi-Legend Alarm Indicator conforms to EN 45545 and offers connectivity with up to 36 tiles in each module and is suitable for 24 and 110 VDC systems. Its modular construction ensures short engineering and production lead-times even for new product configurations.
