This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
The product/system described in this documentation may be operated only by
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.

Product description
Features for devices
IOT2000 Extension Modules provide IOT2000 system with a variety of standard industrial
input/output interface, which can provide customers with more applications.
Although the IOT2000 Extension Modules have an ARDUINO UNO R3 compatible interface,
we designed and tested for use with IOT2020 and IOT2040.
● Work both for IOT2020 and IOT2040
● Depending on the industrial area of application.
– IOT2000 Input/Output Module: has five digital inputs, two analog inputs and two digital
outputs.
– IOT2000 Input Module Sink/Source: only has ten digital inputs.

NOTICE
Observe immunity to RF radiation
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit
(https://www.siemens.com/industrialsecurity).
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed under (https://www.siemens.com/industrialsecurity).
The device has an increased immunity to RF radiation according to the specifications on
electromagnetic compatibility in the technical specifications.
Radiation exposure in excess of the specified immunity limits can impair device functions,
result in malfunctions and therefore injuries or damages.
Read the information on immunity to RF radiation in the technical specifications.
