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.

Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified for the specific task in accordance with the relevant documentation,
in particular its warning notices and safety instructions. Qualified personnel are those
who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.
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.

20MC50M00 E5 2020-10-20 11
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
20MC50M00 E5 2020-10-20 14
1 Product Overview
1.1 Product Description
Low Power CPU for IoT/Network Applications
The MC50M is a modular computer for embedded applications in transportation, e.g.,
trains, buses or commercial vehicles. The computing platform features an Intel Atom
E3900 series CPU with low power dissipation and scalability in performance and
memory.
The MC50M is the ideal basis for functions such as security gateway, predictive
maintenance, CCTV or ticketing system, or to act as a diagnostics server.
Modular System for Easy Configuration
The MC50M can be a stand-alone product, but due to the modular concept it offers
flexible built-to-order configurations. The box can be easily combined with prefabricated
extension modules, providing additional features and short delivery times.
In the modular system, the data transfer between the modules as well as the power
distribution between the individual modules takes place via the extension connectors
standardized by duagon.
Extension modules can provide application-specific functions like wireless
communication (LTE advanced, WLAN, GNSS), MVB, CAN bus, or other I/O. A removable
storage shuttle can support the integration of a 2.5" SATA HDD/SSD. With a PSU
extension module, ultra wide range isolated power supply from 24 V DC to 110 V DC
nominal (EN 50155) is available.
Power Saving Design and Security Features
The board management controller provides enhanced reliability and reduced downtime.
The Trusted Platform Module supports security and encryption features. With the
ignition switch for remote control of booting and shutdown, the platform provides
additional features for power saving.
Flexible System Installation
Various mounting options facilitate the integration of the box into an existing
environment. The standard 35 mm DIN Rail mounting offers space saving mounting of
all system modules on a single rail. Wall mounting and mounting in a 19" rack using
adaption brackets are an option.
The aluminum housing with cooling fins allows fanless operation. MC50M has no
moving parts, making it maintenance free.
Rolling Stock Qualified and Long-Term Availability
The CPU module is qualified for rolling stock and wayside applications. Long term
availability until 2027 minimizes life-cycle management by making the MC50M available
at least for this period of time.
