3.3. Principle of operation
Area of application
A Pt100 / Pt500 / Pt1000 temperature sensor, linear resistor or
potentiometer can be connected to the input of the DT1012 IP…
Temperature / Resistance / Potentiometer Transmitter.
When a Pt temperature sensor is connected, the output signal is
proportional to the measured temperature, in the case of resistance,
to the measured resistance, in the case of a potentiometer, to the
position of the potentiometer.
The output signal can be current in the range 4-20 mA (passive
output, external power supply required).
The instrument has three-way separation, that is: the input, output and
power supply are galvanically independent from each other.
Sensors / transmitters can be connected to the input with 2 / 3 / 4
wires. In case of 3 / 4 wire connection, the resistance of the
connecting wires does not affect the measurement.
The instrument can be scaled, and any input signal range can be
assigned to the output signal range.
Scaling, selection of the output signal level, signal averaging, etc., are
done via USB port.
The configuration program running on the PC and the USB cable are
included with the instrument.
The transmission characteristics of the transmitter are exceptionally
good: the error of the output signal < ±0.1 °C, the temperature factor
< ±20 ppm / °C typically.
There are three types depending on the measuring range:
•DT1012 IP Pt100 measuring range: Pt 100 / 0-400 ohm
•DT1012 IP Pt500 measuring range: Pt 500 / 0-4000 ohm
•DT1012 IP Pt1000 measuring range: Pt 1000 / 0-4000 ohm
(Ptxx measure range: -200 - +800 °C)
There are two type of power supply:
•DT1012 IP... 24 VDC,
•DT1012 IP... PS 230 V AC/DC
Configuration from the PC:
The input and output characteristics can be freely configured from a
PC via a USB port.
The PC program required for configuration is included with the
instrument and can be downloaded from the www.datcon.eu website.
The USB interface is separated from the output of the instrument and
the power supply, but not from its input, so the PC can only be
connected to the instrument under operating conditions with due care.
The instrument is also powered by the USB port, so it is sufficient to
connect the USB cable for configuration (in this case, the analog
output does not work).

Principle of operation
The Pt sensor, resistor, potentiometer connected to the input is sent to
the input of the 24-bit A/D converter through the protection and signal
conditioning stages. The digital signal of the A/D converter is
processed by a microcontroller.
The microcontroller performs signal processing according to the
settings and outputs the signal in the form of a PWM signal for the
output stage. After galvanic isolation, the output stage converts it into
an analog current signal (passive output, external power supply
required).
The instrument generates the power supply voltages required for the
input side and the output side from the connected power supply using
a galvanically separated, double-output DC-DC converter.
Power supply The (PS) can be ordered with two types of power supply:
DT1012 IP: 24 VDC
DT1012 IP PS: 230 V AC/DC
3.4. Setting
After the instrument is connected to the power supply — see
6.1. First power on with factory settings according to chapter —
ready for operation.
A detailed description of the settings can be found in
chapter 7. Setting-up.

connector and indicators:
1. USB-B mini 5-pin female connector for connecting a USB cable.
2. "error" indicator, which indicates the error state with a red, flashing
light. The sequence number of the error is given by the number of

3. "on" indicator, which indicates the switched-on state of the
instrument with a continuous green light.
3.6. Storage and transport
This instrument should be stored and transport in places whose
climatic conditions are in accordance with chapter 10.1. Technical
specification, as described under the title: Environmental conditions.
The packaging of DT1012 IP consist of environment-friendly,
recyclable cardboard is used to protect the instrument against the
impacts of normal stresses occurring during transportation. The
corrugated cardboard box is made from environment-friendly,
recyclable paper. The inner protective material is nylon, which should
be disposed of via specialized recycling companies.

4. Mounting
4.1. General instructions
The instrument should be installed in a cabinet with sufficient IP
protection, where the operating conditions are in accordance with
chapter 10.1. Technical specification, as described under the title:
Ambient conditions
Mounting position
The instruments are designed in a housing for mounting on TS-35 rail.
The instruments should be mounted in vertical position (horizontal rail
position).
If several instruments are placed next to each other in a horizontal
installation position (vertical rail), it may cause the instrument to
overheat.

4.3. Mounting
The following figure shows the mounting procedures (fixing on the
rail):
Mounting on the rail
No tools are required for installation.
1. In the position shown in the figure, place the fixing groove of the
instrument on the upper edge of the rail (step 1 in figure).
2. Push the lower part of the instrument towards the lower edge of the
rail until you hear a clicking sound (fig. step 2).
3. Check whether the fixing is correct by moving the instrument
housing slightly.

5. Connecting
5.1. Preparing the connection
Select and prepare
connection cable
Always observe the following safety instructions:
•The connection must be carried out by trained and authorized
personnel only!
•Connect only in the complete absence of supply voltage
•Use only a screwdriver with appropriate head
Take note the suitability of the connecting cable
(wire cross-section, insulation, etc.).
The wire cross-section should be 0.25-1.5 mm2.
You may use either solid conductor or flexible conductor.
In case of using flexible conductor use crimped wire end.
For the input connection we recommended to use screened cable.
It’s an important rule that the power cables and signal cables should
lead on a separate way.

5.6. Connecting to PC via USB cable
The following figure shows the wiring plan, connecting the instrument
to The PC:
1. Open the front cover of the instrument (from bottom to top).
2. To communicate with the configuration program, plug the included
USB cable (USB-B mini, 5-pin connector) into the "USB" socket
marked with the number (1) in the figure above. The design of the
cable is such that it can only be connected to the instrument in one
position.
The same applies to the cable end on the PC side.
3. Make the desired settings as described in chapter 7. Setting-up.
USB driver installation is not required. It is not necessary to supply the
instrument with power while making the settings. After completing the
settings, simply unplug the USB cable from the instrument. (Don't
move it sideways or jerk it, just pull it.)
The USB port and the input of the instrument are not galvanically
isolated, so the PC can only be connected to the instrument under
operating conditions if the potential difference between them is
negligible (a balancing current of less than 1 mA flows between the
PC and the instrument).
It is not necessary to turn off the instrument when connecting or
disconnecting the USB cable.
