The data refers to nominal operation (UA = 24 V) in the
preferred mounting position (horizontal).
The measurement is performed within an Axioline F station in which another AXL F UTH4 1H module is located
to the right and left of the module in question.
The drift values refer to the full measuring range final
value, i.e., 1372°C in the case of TC sensor
type K, +400°C in the case of the external Pt 100, and
+100 mV in the case of the linear voltage.

Notes on the tolerance tables
The following notes apply for the tables:
– Tolerances of the measuring inputs at TA = +25°C
– Tolerances for TC sensor type K with internal cold junction compensation
1. The measurement is performed within an Axioline F station in which another AXL F UTH4 1H module is located
to the right and left of the module in question.
2. In order to achieve optimum accuracy in the various
mounting positions of the station, different installation
positions can be configured.
3. The tolerance values for the TC inputs are based on the
average basic values for sensitivity (see table for measuring ranges of the TC inputs).
4. The typical values were determined from the maximum
tolerances of the measured practical values.
5. The maximum tolerances represent the worst-case
measurement inaccuracy. They contain the theoretical
maximum possible tolerances in the measuring ranges
as well as the theoretical maximum possible tolerances
of the test and calibration equipment. The data is valid
for at least 24 months from delivery of the module.
Thereafter the modules can be recalibrated by the manufacturer at any time.
6. An additional path calibration function for maximum accuracy is possible at any time in the application (see object 008Fhex path calibration values). Using the
temperature offset, you can finely tune the tolerances
for each channel by means of the connecting cables
and the sensors. The specified tolerances are then reduced accordingly.
7. The tolerances increase slightly for a short time immediately after power up (see switch-on behavior section).
8. In the -100 mV ... +100 mV linear voltage input range,
smaller measuring windows with closer tolerances were
also specified. The reference value of the relative tolerance value is always based on +100 mV.
9. Please note when using linear voltage signals: for voltages above +32.7 mV and below -32.7 mV, parameterize the process data resolution as 10 µV/LSB (instead
of 1 µV/LSB) in order to prevent overrange or underrange messages from occurring.
10. Always position temperature modules at the end of the
station. For modules that must be positioned next to a
bus coupler, the typical measuring tolerance can be increased by up to 0.9 K.
11. The maximum tolerances are observed even in the
event of electromagnetic interference (see also Table
"Tolerances influenced by electromagnetic interference"). They apply for both shielded and unshielded I/O
cables.

The switch-on behavior must only be taken into consideration for TC measurements with internal cold junction
temperature, it does not apply for differential measurements or measurements with external compensation.
The typical characteristic curves of the TC inputs after
power up were recorded in the preferred mounting position (horizontal), in nominal operation (UA = 24 V,
TA = 25°C), and with unobstructed ventilation ducts
(free air flow).
The measurement is performed within an Axioline F station in which another AXL F UTH4 1H module is located
to the right and left of the module in question.
Different installation positions or arrangements where
the module is affected by external sources of heat can
result in a different thermal switch-on behavior.
The measuring probes of the type K TC sensors were
kept at a constant temperature.
Even in the event of extreme temperature fluctuations in the
environment where the Axioline F station is located, the system operates very quickly and precisely. There is also the
option of adjusting all sensor and cable tolerances in the application via an additional path calibration function.

In the event of sudden changes in the ambient temperature
of the temperature module (e.g., from TA = +25°C to
TA = +60°C), the time curve for the transient response is
comparable with that of the switch-on behavior.

ExternalPt 100 cold junctions
Technical data for cold junctions
To read the temperature of each internal cold junction for TC
channels, parameterize the sensor type as "Cold Junction".
When using external isothermal blocks or distributed terminal boxes, an external cold junction is recommended. The
advantage of this is an improved switch-on behavior and the
very fast thermal transient period in the event of sudden
changes to the ambient temperature of the measuring station.
For the accuracy, please refer to the tables of the tolerance
values.
You can connect up to two Pt 100 sensors to the
AXL F UTH4 1H module.
Internal cold junctions
Simple cold junction compensation can be implemented for
the thermocouple inputs using the internal cold junctions.

You can also use the inputs for the external cold junction
sensors as sensor inputs for any applications with Pt 100
and connection with 2-wire technology. To do so, parameterize the sensor type as “Cold junction” and the cold junction type as “External Pt 100” on the corresponding connector.

The documented typical tolerances were determined for reference cable type LiYCY (TP) 2 x 2 x 0.5 mm² with a connection length 100 m) with a temperature
transducer (e.g., MCR-T-UI-E) in 4-wire technology and
read them in via the -5 V ... +5 V input. You can use this for
external cold junction compensation of very remote control
boxes, if copper TC sensor cables need to be used.

Universal AC and DC current acquisition in
combination with a current transducer
Any AC or DC currents with 300 V AC safe isolation according to EN 50178, EN 61010, such as heating currents, can
be acquired via the ±5 V voltage input (terminal points 02
and 12) using a current transducer.
For signal conditioning, use the MCR-S-1-5-UI(-SW)-DCI
current transducer from Phoenix Contact, for example.

Connection notes
Use encapsulated thermocouples.
Always connect the thermocouples using twisted pair equalizing conductors.
Use shielded twisted pair equalizing conductors for a cable
length from 10 m.
For mV sensors in environments prone to interference as
well as for sensor cables which are longer than 10 m. use
shielded twisted connecting cables (e.g., LiYCY (TP) 2 x 2 x
0.5 mm2).
For TC sensors, use the corresponding shielded TC connecting cable according to DIN EN 60584-3/ISO 60584-3.
For optimum shield connection directly before the module,
use the AXL SHIELD SET Axioline shield connection set
(see ordering data).
Please refer to the UM EN AXL SYS INST user manual for
information on how to install the set and connect the shield.
For installation in a control cabinet: connect the cable shield
to functional earth ground immediately after the cables enter
the control cabinet. Route the shield as far as the Axioline F
temperature module without interruption.
10
Configuration notes
Always position temperature modules at the end of the station. For modules that must be positioned next to a bus coupler, the typical measuring tolerance can be increased by up
to 0.9 K.
Make sure that the shielded twisted sensor
cable is no more than 5 m in length from the
current transducer to the temperature module.
If longer cable lengths are required, connect
appropriate converters or signal conditioners
upstream.
The MCR range from Phoenix Contact offers
a comprehensive range of products for this.

There are several internal cold junction sensors in the module.
When you select the "Internal" cold junction
type for a channel, the corresponding cold
junction for this channel is automatically assigned to it.
External
You can connect a Pt 100 sensor to every
connector as an external cold junction sensor. Up to four external cold junctions are
therefore available. One of these four external cold junctions can be assigned to each
of the eight channels.
Process data This parameterization offers the following
option:
Determine the temperature of the cold junction via an additional device.
Transfer this temperature to the temperature module via the first process data output
word. Use IB IL format with a resolution
of 0.1°C.

Extended Float Format
Extended Float Format is a specially defined format. It consists of the measured value in float format, a status, and a
unit.
Status is necessary because the float format defines no patterns providing information on the status of the numerical
value.
The status corresponds to the LSB of the diagnostic code in
IB IL format (e.g., overrange: status = 01, diagnostic code =
8001hex). If status = 0, the measured value is valid.

Local adjust values (008Fhex)
This object supports a channel-specific path calibration function for maximum accuracy. This means, for example, that you
can finely tune the tolerances by means of the TC connecting cables and the sensors.
The calibration data is permanently stored on the module.
The object contains the temperature offset of the cold junction with reference to each channel in IB IL format with a resolution
of 0.1°C.

Writing the analog values over the
PDI channel
PDI = Parameters, Diagnostics and Information
To set the temperature of the external cold junction via the
PDI channel rather than in the process data, you must
change the exclusive right first.
To do this, proceed as follows:
• Write the ASCII string "Superuser" to the "Password"
(001Dhex) object.
• Write the value 01hex to the “Request exclusive write access” object (0027hex).
