HMI System – Multi-Legend Alarm Indicator
Flexible, bright and reliable alarm indicator – with minimal back panel depth, and developed for driver’s cabs this modular HMI simplifies fault monitoring contributing to increased safety within railway applications.
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 diverse mounting options, and very low back panel depth of just a few millimetres 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.
Every alarm indicator is electrically independent to guarantee high operational safety and 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 or tactile dimmer switch 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 both fixed and interchangeable symbols.
