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%

3.5. 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

5. Connecting
5.1. Preparing the connection
Select connection
cable
Preparing cables
Always observe the following safety instructions:
•The connection must be carried out by trained and authorized
personnel only!
•Connect or disconnect only in the complete absence of line voltage
•You should take note the data concerning on the overcurrent
protection in installation.
•Use only a screwdriver with appropriate head
Take note the suitability of the connecting cable
(wire cross-section, insulation, screening, etc.).
You may use either solid conductor or flexible conductor.
In case of using flexible conductor use crimped wire end.
The instrument can be 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. Ground the cable shield on the cabinet side.
Always lead the signal cables on a separate path from the control and
power cables!
Prepare the cable for the connection. Strip approx. 8 mm insulation.
In case of using flexible conductor use crimped wire end.
