3.3. Operating principle
Area of application The DT1102 (PS) Switch Configurable I/O Galvanic Isolator
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 instrument has two inputs:
1. 0(4)-20 mADC current or*
2. 0(2)-10 VDC voltage*
and two outputs:
1. 0(4)-20 mADC current or*
2. 0(2)-10 VDC voltage.
* only one input and one output are active together
The input/output ranges are switch selectable.
The DT1102 (PS) - providing a 20 VDC, 20 mA supply on the input –
for supplying 4-20 mA passive transmitters.
The front panel LED indicators provide information about the
operating status of the device. (power on state, error states)
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 a
24 bit 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, measuring
value. The output pulse is galvanic isolated by an optocoupler. After
filtering the pulse is converted into analogue current or voltage signal.
The input/output ranges are switch configurable.
The internal power supplies are generated by an isolated dual output
DC/DC converter, using planar transformer technology.
Power supply The instrument has two different power supply version:
DT1102:
Power supply: 24 VDC ±10%
DT1102 PS:
Power supply: 230 V AC/DC ±10%

3.4. Indicators, configuration switches
The following figure shows the indicators and the configuration
switches on the DT1102 (PS) front panel.
(1) configuration switches for selection input/output ranges
(2) red „error” indicator shows the error states
(3) green „on” indicator shows the power on state

3.5. Input/output signal selection
Four different input/output signal range can be selected with the front
panel switches:
0-20 mA, 4-20 mA, 0-10 V, 2-10 V
Default setting: 0-20 mA input, 0-20 mA output
(all switches are in „off” state).
The following figure shows the input/output signal range selection
table:
The following figure shows steps of setting:
1. Take the instrument in hand according to the figure
2. Open the front panel cover with the enclosed tool according to the
figure
DT1102 (PS)

3. Set the configuration switches according to the signal range
selection table
4. Close the front panel cover
Do not use other tool than the enclosed one because you may cause
injury either to switches or to front panel!
3.6. Storage and transport
This instrument should be stored and transport in places whose
climatic conditions are in accordance with chapter 9.1. Technical
specification, as described under the title: Environmental conditions.
The packaging of DT1102 (PS) 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.
