3.3. Operating principle
The DT1100 xx xx Galvanic Isolator / Power Supply provide
signal transmission and conversion between transmitters
and signal processing units.
The instruments feature complete 3-way isolation: the input,
the output and the power supply are isolated from each
other.
The DT1100 xx xx - providing a 20 VDC, 25 mA supply on
the input - may be used for isolating and supply passive
transmitters, but it can be used for active output transmitters
too.
20131126-V0
DT1100 xx xx
Principle of operation
The input current flows through the measuring resistor or
the input voltage divides through the attenuator. This
voltage drop is led to an A/D converter. The digital output
signal of the A/D converter is processed by a
microcontroller.
The microcontroller produces a pulse width modulated
(PWM) output signal. The pulse width is proportional to the
processed, scaled measuring value. The output pulse is
galvanic isolated by an optocoupler. After filtering the pulse
is converted into analogue current or voltage signal.
When the output signal is frequency than the microcontroller
produces a frequency signal (0.2-1 kHz) proportional to the
processed, scaled measuring value. The frequency signal is
galvanic isolated by an optocoupler and led to an output
transistor.
Power supply
The DT1100 xx xx is available with two different power
supply:
DT1100 xx xx:
19-50 VDC / 19-35 VAC
DT1100 xx xx PS:
90-250 V AC/DC
Power consumption: 1.8 W max.
The overcurrent protection in installation is 4 A (B).
3.4. Adjustment
The DT1100 xx xx doesn’t need any adjustment.
After connecting to the power supply the instrument ready to
work.

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 8.1. Technical specification,
as described under the title: Operating conditions.
Mounting position
The DT1100 xx xx is built in a plastic housing, for mounting
on TS-35 rail.
The instrument should be mounted in vertical position
(horizontal rail position).

on the rail):
Mounting on the rail
The mounting doesn’t need any tools.
1. Tilt the instrument according to the figure; put the
instrument’s mounting hole onto the upper edge of the rail
(figure step 1.).
2. Push the instrument’s bottom onto the bottom edge of the
rail (figure step 2.), you will hear the fixing assembly

5. Connecting
5.1. Preparing the connection
Always observe the following safety instructions:
• Connect or disconnect only in the complete absence of
line voltage
• If overvoltages are accepted, overvoltage arresters
should be installed
• You should take note the data concerning on the
overcurrent protection in installation.
• Use only a screwdriver with appropriate head
Select connection
cable
Take note the suitability of the connecting cable
(wire cross-section, insulation, screening, etc.).
The instrument is connected with standard two-wire cable
without screen.
If electromagnetic interference is expected which is above
the test values of the correspondent standard for industrial
areas (e.g. high power frequency drives are working in the
area) screened cable should be used.
You may use either solid conductor or flexible conductor.
In case of using flexible conductor use crimped wire end.
Preparing cables
Prepare the cable for the connection. Strip approx. 8 mm
insulation.
In case of using flexible cable, crimp the cable end.
The following figure shows preparing of screened cable:
Cable screening and
grounding
Ground the cable screen on the instrument side.
20131126-V0
Always lead the signal cables on a separate path from the
control and power cables!
