3.3. Operating principle
Area of application The DT1102 V (PS) Fully Configurable Galvanic Isolator provide
signal transmission and conversion between DC current or DC voltage
signal source 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 instruments has three inputs:
1./ -25 mA - +25 mA DC current,*
2./ -2.5 - +2.5 V DC voltage,*
3./ -125 - +125 V DC voltage.*
The instruments has two outputs:
1./ 0 - 22 mA DC current,*
2./ 0 – 10.5 V DC voltage.*
* You must use one input and one output at a time.
The PC configurator software is accessory or free downloadable from
homepage: www.datcon.hu
The input type and range and the output type and range are
configurable (current or voltage). See chapter 10.1. Technical
specification.
The input is bipolar, symmetrical.
The output is unipolar.
The configuration parameters can be download from
the PC to the DT1102 V via USB port.
The front panel LED indicators provide information about the
operating status of the device.
Principle of operation
The input current flows through the measuring resistor or the input
voltage is divide by the attenuator. This voltage is measured by 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 output signal
which is proportional to the processed, scaled measuring value. The
output pulse is galvanic isolated by an opto coupler. After filtering the
pulse is converted into analogue current or voltage signal.
Connecting the instrument to the PC through the USB interface the
instrument’s communication circuitry come into active state and it is
ready for communication with the configuration software.

The USB port is galvanic isolated therefore the USB cable can
plugged into a grounded PC too.
Power supply The DT1102 V (PS) is available two different power supply:
DT1102 V:
Power Supply: 24 VDC ±10%
DT1102 V PS:
Power Supply: 230 V AC/DC ±10%
3.4. Adjustment
After connecting the DT1102 V is ready to work with the factory
default parameters are written in chapter 6.1. The first start-up. For
working with the default parameters there is no need any adjustment.
The detailed description of the setup can be found in chapter 7.

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: Ambient conditions.
The packaging of DT1102 V 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 polyfoam and 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).
Horizontal mounting may cause overheating and damage of the
instrument.

rail):
Mounting on the rail
The mounting doesn’t need any tool.
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 closing.
3. Check the hold of the fixing by moving the instrument firmly.

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 supply
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, 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.
Prepare the cable for the connection.
Strip approx. 8 mm insulation.

6. The first start-up, indicators
6.1. The first start-up
After connecting the DT1102 V is ready to work with the factory
default parameters.
When you are going to use other parameters you should set-up the
instrument according to chapter 7. Setting-up.
Factory default settings:
•Input signal: Current
•Input initial value: 0 mA
•Input end value: 22 mA
Used input terminals are Common (7) and Iin (8).
•Output signal: Current
•Output initial value: 0 mA
•Output end value: 22 mA
Used output terminals are -Iout (5) and +Iout (6).
The unappropriate settings or the different between settings type and
used terminals type makes measurement error happen.

6.2. Indicator LED-s
The following figure shows the indicators and USB connector on the
DT1102 V front panel.
(2) The blinking light of „error” red indicator indicates different error
states.
(3) The continuous light of „on” green indicator indicates that the
instrument is working.
• Error state:
“on” indicator: light, “error” indicator: blinking.
The number of blinks gives the error information:
1 blink: fatal error. (repairing: in factory service only).
4 blinks: input range error. (check the settings parameters and the
value of the input signal).
5 blinks: output range error (check the settings parameters).
