Function description
The terminal is designed for use within an Inline station. The
terminal has four inputs that may be configured
independently of each other and either for measuring
voltages or resistances or for RTDs.
The sensors are connected using the 2-wire connection
method, so that a nominal resistance of at least 1000 Ω is
recommended when sensors with a relatively small
temperature coefficient (e.g., platinum sensors) are used.
Features
–
–
The resistance measurement with conversion into
temperature values can be used for the temperature
measurement with NTC resistors. The advantage of these
resistors is a large temperature coefficient.
Thanks to special engineering measures and tests, the
terminal can be used under extreme ambient conditions.
–
–
–
–
–
–
–
Four measuring inputs that can be configured as
– Voltage inputs 0 V ... 10 V
– Inputs for resistance measurements up to 300 kΩ
with output either in ohms or percent
(potentiometer measurement)
– Input for temperature measurements
The terminal supports
– Platinum sensors according to DIN EN 60751/
IEC 60751 and the SAMA guideline
– Nickel sensors according to DIN 43760 and the
SAMA guideline
– KTY81-110, KTY81-210, KTY84 sensors
– Viessmann Ni 500, Viessmann NTC10 k sensors

isolated from all other circuits (UL, main circuit UM, segment circuit US, analog circuit UANA). FE (functional earth ground) is a separate potential area that is
connected with shield and analog ground via a coupling network consisting of a 1 MΩ resistor and a 1 nF capacitor connected in parallel.

Installation instructions
High current flowing through potential jumpers UM and US
leads to a temperature rise in the potential jumpers and
inside the terminal. To keep the current flowing through the
potential jumpers of the analog terminals as low as possible,
always place the analog terminals after all the other
terminals at the end of the main circuit (for the sequence of
the Inline terminals, see also IL SYS INST UM E user
manual).
9
Connection notes
Always connect the analog sensors using
shielded, twisted pair cables.
A shield may reduce the influence of
electromagnetic interference. Connect the shield
at one end with the shield connection of the
terminal and insulate it at the sensor.
Connect unused sensor inputs with sensor
ground.
Connect the shield externally in areas with strong
EMI, and insulate it at the device and the sensor

Process data
11.1
Process data output words OUT
Two process data output words are available.
If you change the configuration, the message "Measured
value invalid" appears (diagnostic code 8004hex), until new
measured values are available.
Configure the terminal channels via the process data output
words OUT1 and OUT2. In this context, the output word
OUT1 contains the command and output word OUT2
contains the parameters belonging to this command.
Please note that extended diagnostics is only
possible if the IB IL format or standardized
representation are configured as the format for
representing the measured values. As the IB IL
format is preset on the terminal, it is available
immediately after the voltage has been applied.
The configuration settings are stored in a volatile memory.

R0
Selecting the resistance of the sensor at 0°C;
The configurable nominal resistance R0 is taken for the
temperature calculation based on nickel and platinum
sensors. Should the desired resistance not be found in the
code table, the nominal resistance of 1 Ω to 65535 Ω can be
configured with increments of 1 Ω. To do this, use the
command 9x00hex with the R0 value in the OUT2 process
data word.
Filter
Selection of mean value generation.
After every conversion, the measured value is saved in a
mean value memory via which the mean value is generated.
The memory size can be selected with the filter option. E.g.,
8360_en_00

for a 16-sample mean value, the mean value is generated
using the last 16 measured values.

Sensor type
Sensor type setting;
The configurable sensor type determines the conversion of
the electrical signal present at the input into a physical size.
Sensor type and measurement mode must be set for a
sensor to be connected to receive a measuring result with a
suitable accuracy. If, for instance, a Pt 1000 sensor is to be
connected, a resistance measurement for the range from
0 Ω ... 3 kΩ can be used as a measurement mode. Also, a
resistance measurement would be possible for the range
from 0 Ω ... 300 kΩ, however, this measurement mode
provides a considerably lower accuracy in the resistance
range relevant for Pt 1000.
Measurement mode
Setting the selected measurement mode;
The measuring mode determines the signal conditioning by
the configurable inputs. Every input can be configured for
voltage or resistance measurement as desired. For the
resistance measurement, an auxiliary current that
generates a voltage drop over the resistance to be
measured is generated. The current supply is deactivated
for the voltage measurement.

In the resistance measurement mode 0 Ω 3 kΩ is limited to 3000.0 Ω.
If the measured value is outside the
representation area of the process data, bit 0 is
set to 1.
In the event of an open/short circuit, bit 1 is set to
1.

representation” on page 16).
The data is standardized with regard to measuring range
and resolution and does not need to be converted. The
setting of the resolution is 1 Ω for resistance measurements
and 1°C for temperature measurements. It has no influence
on voltage measurements.
