Legal information
Warning notice system
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.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
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.
Quali󹪝ed Personnel
The product/system described in this documentation may be operated only by personnel quali󹪝ed for the speci󹪝c
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.

2.5 Intended use
SITRANS TH320/TR320
The SITRANS TH320/TR420 transmitter can be used in all sectors. Its compact size means that it
can be installed in connection heads of type B (DIN 43729) or larger. Due to its universal input
stage, the following sensors and signal sources can be connected:
• Resistance thermometer (2-wire, 3-wire, 4-wire connection)
• Thermocouples
• Linear resistance, potentiometer and DC voltage sources
Without HART communication interface:
• The output signal is a load-independent direct current from 4 to 20 mA in accordance with
the input characteristic.
With HART communication interface:
• The output signal is a load-independent direct current from 4 to 20 mA in accordance with
the input characteristic, superimposed by the digital HART signal.
Transmitters of the "intrinsically safe or Zone 2 increased safety" type of protection can be
installed in hazardous areas. The device meets the requirements of the EU Directive 2014/34/EU
(ATEX), the FM and CSA regulations as well as other national approvals, e.g. EACEx, NEPSI, KCs,
Inmetro.

SITRANS TH420/TR420
The SITRANS TH420/TR420 transmitter with two inputs can be used in all sectors. Its compact
size means that it can be installed in connection heads of type B (DIN 43729) or larger. Due to
its universal input stage, the following sensors and signal sources can be connected:in
redundant operation (high input availability):
• 2 resistance thermometers (2-wire, 3-wire, 4-wire connection)
• 2 thermocouples
• 1 thermocouple and 1 resistance thermometer (2-, 3-, 4-wire connection)
• 2 linear resistances, potentiometer and DC voltage sources
The output signal is a load-independent direct current from 4 to 20 mA in accordance with the
input characteristic, superimposed by the digital HART signal.
The dual input mode also supports drift detection of the inputs, whereby maintenance intervals
can be more easily planned.
Transmitters of the "intrinsically safe or Zone 2 Increased Safety" type of protection can be
installed in hazardous areas. The device meets the requirements of the EU Directive 2014/34/EU
(ATEX), the FM and CSA regulations as well as other national approvals, e.g. EACEx, NEPSI, KCs,
Inmetro.
SITRANS TF320/TF420
The SITRANS TF temperature transmitter converts sensor signals into a load-independent DC
signal according to the sensor characteristic. The following sensors and signal sources can be
connected to the input block:
• Resistance thermometer
• Thermocouples
• Resistance-based sensor/potentiometer
• DC voltage sources
The output signal is a load-independent direct current from 4 to 20 mA in accordance with the
input characteristic, superimposed by the digital HART signal.
Transmitters of the "intrinsically safe or Zone 2 Increased Safety" type of protection can be
installed in hazardous areas. The device meets the requirements of the EU Directive 2014/34/EU
(ATEX), the FM and CSA regulations as well as other national approvals, e.g. EACEx, NEPSI, KCs,

2.8 Security information
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 constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected to
an enterprise network or the internet if and to the extent such a connection is necessary and only
when appropriate security measures (e.g. 󹪝rewalls and/or network segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
visit
https://www.siemens.com/industrialsecurity.
Siemens’ products and solutions undergo continuous development to make them more secure.
Siemens strongly recommends that product updates are applied as soon as they are available
and that the latest product versions are used. Use of product versions that are no longer
supported, and failure to apply the 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.
2.9 Transportation and storage
To guarantee su󹪟cient protection during transport and storage, observe the following:
• Keep the original packaging for subsequent transportation.
• Devices/replacement parts should be returned in their original packaging.
• If the original packaging is no longer available, ensure that all shipments are properly
packaged to provide su󹪟cient protection during transport. Siemens cannot assume liability
for any costs associated with transportation damages.
NOTICE
Insu󹪟cient protection during storage
The packaging only provides limited protection against moisture and in󹪝ltration.
• Provide additional packaging as necessary.
Special conditions for storage and transportation of the device are listed in Technical data
(Page 73).
