3 For your safety
The product is designed according to state-of-the-art technology. However, residual risks still
exist. Observe the following warnings and safety notices to prevent damage to persons and
property. Turck accepts no liability for damage caused by failure to observe these warning and
safety notices.
3.1 Intended use
The compact processing and display units of the TS720… product series are designed for meas-
uring temperatures in machines and plants. This requires the connection of a temperature
probe to the devices. The temperature processing and display units support the connection of
resistance thermometers (RTD) and thermocouples (TC).
The devices may only be used as described in these instructions. Any other use is not in accord-
ance with the intended use. Turck accepts no liability for any resulting damage.
3.2 Obvious misuse
nThe devices are not safety components and must not be used for personal or property
protection.
3.3 General safety instructions
nThe device meets the EMC requirements for industrial areas. When used in residential areas,
take measures to avoid radio interference.
nThe device may only be assembled, installed, operated, parameterized and maintained by
professionally-trained personnel.
nThe device may only be used in accordance with applicable national and international regu-
lations, standards and laws.
nOnly operate the device within the limits stated in the technical specifications.

4 Product description
The temperature processing and display units of the TS+ series are contained in a metal hous-
ing and provided with a G1/2” process connection. The sensor head can also be rotated by 340°
after installation. The devices have a metal M12 connector (male) for connecting the sensor
cable. Another M12 connector (female) is provided for connecting resistance thermometers
(RTD) and thermocouples (TC).
Devices with the following output functions are available:
nTS…LI2UPN…: 2 switching outputs (PNP/NPN/Auto) or 1 switching output (PNP/NPN/Auto)
and 1 analog output (I/U/Auto)
nTS…2UPN…: 2 switching outputs (PNP/NPN/Auto)

4.3 Operating and display functions
The front of the device is provided with three touchpads [ENTER], [MODE] and [SET], a 4-digit
12-segment multicolor display and status LEDs. This enables the user to set all essential func-
tions and properties directly on the device and read the actual process values and set switching
points.
4.4 Operating principle
Standard Pt100 and Pt1000 resistance thermometers (RTD) as well as thermocouples (TC) can
be connected to the temperature display and processing unit. The temperature value meas-
ured on the attached probe is passed on to the higher-level I/O. The device display shows the
temperature value in the unit selected by the user.

TS…LI2UPN… 2 switching outputs (PNP/NPN/Auto) or 1 switching output (PNP/NPN/
Auto) and 1 analog output (I/U/Auto)
TS…2UPN… 2 switching outputs (PNP/NPN/Auto)
A window function or a hysteresis function can be set for the switching outputs. The measuring
range of the analog output can be defined as required. The measured temperature can be
displayed in °C, °F or K, or the resistance can be displayed in Ω if a resistance thermometer is
connected. The devices can be parameterized via IO-Link and via touchpads. The following
temperature probes can be connected to the device:
nResistance thermometers (RTD)
– Pt100 (2-, 3-, 4-wire)
– Pt1000 (2-, 3-, 4-wire)
nThermocouples (TC)
– Type K, B, E, J, N, R, S and T
4.5.1 Setting options
The devices have three setting options:
nSetting via IO-Link
nSetting via touchpads
nSetting via FDT/DTM
4.5.2 Normal operation — run mode
The device detects the temperature on the probe and shows the required switching or analog
behavior according to the factory-set or customer-specific parameters. The display indicates
the process temperature present, the selected unit and the status of the switching outputs.
4.5.3 Programming mode
When the sensor is unlocked, the display will go into programming mode after the user presses
the [MODE] touch pad. In programming mode, all parameters and their corresponding values
can be read out and changed. The values for a parameter are displayed by briefly pressing the
[ENTER] touch pad. The [MODE] and [SET] touch pads are used to navigate within programming
mode. For more information, refer to the chapter “Setting and parameterization.”

4.5.4 Output functions — switching output
A window function and a hysteresis function can be set for the switching outputs.
Window function
The window function is used to set a switching range in which the switching output takes on a
defined switching state. The switching range is defined by means of an upper (FH) and lower
limit (FL). The minimum distance between the limits is 0.2K. If the upper limit is changed, the
lower limit value is adjusted automatically.

Hysteresis function
The hysteresis function is used to set a stable switching state around a setpoint that is inde-
pendent of system-related temperature fluctuations. The switching range is defined by means
of a switching point (SP) and a release point (rP). The minimum hysteresis is 0.2K. If the switch-
ing point is changed, the release point is adjusted automatically.

4.5.5 Output functions – analog output
The minimum distance between the start and end point is 0.2K.
The analog output of the TS720…LI2UPN8 devices can be set as either a current or voltage
output. The output range is freely scalable to the measuring range.
Current output
In the defined measuring range, the device supplies an analog current signal between ASP
(analog start point) and AEP (analog end point). The following output configurations can be set:
n4…20mA (factory setting)
n0…20mA
n20…4mA
n20…0mA
Voltage output
In the defined measuring range, the device supplies an analog voltage signal between ASP
(analog start point) and AEP (analog end point). The following output configurations can be set:
n0…10V
n0…5V
n1…6V
n0.5…4.5V (rtio)
n10…0V

4.5.6 IO-Link mode
In order to operate in IO-Link mode, the device must be connected to an IO-Link master. When
the port is configured in IO-Link mode, bidirectional IO-Link communication takes place
between the IO-Link master and the device. To make this possible, the device is integrated via
an IO-Link master at the control level. First the communication parameters are exchanged, and
then the cyclic data exchange of process data (objects) starts.
4.5.7 SIO mode (standard I/O mode)
In standard I/O mode no IO-Link communication takes place between the device and the
master. The device only transfers the switching state of its binary outputs and can also be run
via a fieldbus device or controller with digital PNP or NPN inputs. An IO-Link master is not re-
quired for operation.
The device parameters can be set via IO-Link and then operated at the digital inputs with the
appropriate settings in SIO mode. Not all functions and properties of the device can be used in
SIO mode.
4.5.8 Auto detect function
The device uses the auto detect function to detect whether a resistance thermometer or a ther-
mocouple is connected. The type of thermocouple is determined by the user. When connected
to an I/O module, the device detects the pre-defined switching output behavior (PNP/NPN) or
the analog output characteristic. The auto detect function is activated by default.

5 Installing
The temperature processing and display unit features a G1/2″ thread (SW30) for mounting with
an application-specific mounting bracket. Alternatively, the device can be mounted with the
FAM-30-PA66 (ID100018384) mounting bracket. The display of the unit can be rotated by 180°
(see figure and parameter DiSr).
Fig.7: Installing TS720…
Mount the temperature processing and display unit on any part of the plant. Observe the
technical specifications for mounting (e.g. ambient temperature).
Optional: Rotate the sensor head within the 340° range to align the connection to the
I/O level as well as to ensure optimum operability and readability.

6 Connection
NOTE
For USA/Canada: The devices must be supplied with limited energy in accordance
with UL 61010-1 3rd Edition, section 9.4 or LPS in accordance with UL 60950-1 or
Class 2 in accordance with UL 1310 or UL 1585. Connect the sensor to a separated
extra-low voltage (SELV) power supply.
The connection cables between the temperature probe and the compact processing
and display unit must have a rated operating temperature of at least 75°C and a
rated voltage of at least 300V RMS.
Standard 2-, 3- and 4-wire Pt100 and Pt1000 resistance thermometers (RTD) as well as thermo-
couples (TC) of types K, B, E, J, N, R, S and T can be connected to the temperature processing
and display unit.
