Product Safety
Product Safety
Read the user manual carefully before using the product. Keep the user manual for later
reference.
Conditions for Use, Field of Application
The product is designed to function correctly in the market, application area and
environmental conditions specified in the applicable standards which are listed in the
Technical Data.
Use cases in environments exceeding the specifications in the applicable standards and
the Technical Data have to be agreed upon between duagon and the customer.

Electrostatic Discharge (ESD)
Computer boards and components contain electrostatic sensitive devices.
Electrostatic discharge (ESD) can damage components. To protect the PCB
and other components against damage from static electricity, follow some
precautions whenever you work on your computer.
Power down and unplug your computer system when working on the
inside.
Hold components by the edges and try not to touch the IC chips, leads,
or circuitry.
Use a grounded wrist strap before handling computer components.
Place components on a grounded antistatic pad or on the bag that came
with the component whenever the components are separated from the
system.
Only store the product in its original ESD-protected packaging. Retain
the original packaging in case you need to return the product to duagon
for repair.

20DC19-00 E1 2020-10-27 9
Product Compliance
Product Compliance
duagon products are tested according to the standards given in the Technical Data and
thus enable you to achieve certification of the product according to the standards
applicable in your field of application.
If the product delivered was certified by duagon and is modified by the customer, e.g., by
installing an additional hardware component, the certification achieved by duagon
becomes invalid and may have to be repeated for the new product configuration.
RoHS
duagon is committed to develop and produce environmentally compatible products
according to the Restriction of Hazardous Substances (RoHS) Directive 2011/65/EU
(formerly 2002/95/EC) of the European Union.
Since July 1, 2006 all duagon standard products comply with RoHS legislation.
REACH
duagon is a manufacturer of electronic products and thus a so-called "downstream
user" in terms of REACH. The products duagon supplies are solely non-chemical goods.
Moreover and under normal and reasonably foreseeable circumstances of application,
the goods supplied shall not release any substance.
Beyond that, according to REACH – Art.33, duagon will inform the customer immediately
should a substance contained in a duagon product (with a content of > 0.1%) be
classified alarming by the European Chemicals Agency (ECHA).
WEEE Application
Nevertheless, duagon is registered as a manufacturer in Germany. The registration
number can be provided on request.
The WEEE directive does not apply to fixed industrial plants and tools. The
compliance is the responsibility of the company which puts the product
on the market, as defined in the directive; components and sub-
assemblies are not subject to product compliance.
Since duagon does not deliver ready-made products to end users, the
WEEE directive is not applicable for duagon. Users are nevertheless
recommended to properly recycle all electronic boards which have passed
their life cycle.

Product Overview
20DC19-00 E1 2020-10-27 12
1 Product Overview
1.1 Product Description
Robust Panel PC for Interactive Rail Applications
The DC19 panel PC is a rugged, fanless and maintenance-free human-machine interface
(HMI) for railway applications. It features a 10.4" display and touch screen or 32
illuminated front keys. Its small, ultra-flat mechanical design and configuration options
save space in the driver cabin and allow the panel to be tailored for all types of
applications in different train models. In addition, its full software compatibility with the
12.1" DC20 panel PC both increases flexibility and lowers costs, e.g., if an upgrade to a
larger panel is necessary.
High-Quality, High-Resolution Display
The DC19 houses a robust impact-resistant XGA TFT LCD display with LED backlight. It
also features LEDs and a light sensor at the front. Due to its high resolution and
optimized usability, it is a perfect choice for, e.g., CCTV.
Powerful & Energy-Efficient Computing
The DC19 is powered by an Intel Atom processor from the E3900 series running at up to
1.6 GHz and equipped with up to 8 GB RAM with ECC and a 32 GB soldered eMMC.
Standard interfaces include two Gigabit Ethernet, one CAN, one audio, digital I/O and
RS232/RS422/RS485 - all available on M12 connectors at the back of the panel PC.
Two PCI Express Mini Card interfaces can control wireless communication functions like
2G, 3G, 4G and GNSS. Two micro-SIM card slots with dual-SIM functionality are accessible
at the back of the panel.
Flexible Rail Network Connection Options
The DC19 can provide Multifunction Vehicle Bus (MVB) master or slave support where
necessary, by adding an MVB PCI Express Mini Card. This makes the display scalable for
different applications.
Extremely Rugged, Perfectly Rail-Ready
The DC19 comes with an extremely rugged housing with an IP65 compliant front. It
supports a railway-compliant power supply of 24 V DC to 110 V DC, its internal PSU
complying with EN 50155 class S2. Also in compliance with the standard, the DC19
operates in a -25 °C to +70 °C environment (+85 °C for 10 minutes), achieved through
fanless conduction-cooling technology.
All electronic components are soldered to withstand shock and vibration, backed up by
solid M12 connectors, and protected by conformal coating. Long-term availability until
2027 ensures an extended product life and future-safety. The panel PC meets all
important requirements for railway equipment for fast, competitive time-to-market even
in mission-critical environments.
