3.3. Operating principle
Area of application The DT1102 M (PS) MODBUS Output 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 bipolar symmetrical 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 one output:
RS485 MODBUS RTU/ASCII slave
* You must use one input at a time.
The PC configurator software is accessory or free downloadable
from homepage: www.datcon.hu
The input type and range and the MODBUS communication
parameters are configurable (current or voltage). See chapter
10.1. Technical specification.
The configuration parameters can be download from
the PC to the DT1102 M 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 divided 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 measured values are
reading from instruments via galvanically isolated RS485 interface
using MODBUS RUT/ASCII protocol.
The instrument’s power supply produces two galvanically isolated
supply voltages, one of for input side and one of for output side.

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 M (PS) is available two different power supply:
DT1102 M: 24 VDC ±10%
<1.2 W / 1.8 VA
DT1102 M PS: 230 V AC/DC ±10%
<1.9 VA / 1.3 W
3.4. Adjustment
After connecting the DT1102 M 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. Setting-up.

3.5. Indicators, USB connector
The following figure shows the indicators and USB connector on
the DT1102 M front panel.
1. USB-B mini, 5 pole connector for connecting to the PC at
configuration.
2. The „error” red indicator blinking light indicates different error
states.
3. The „on” green indicator continuous light indicates that the
instrument is working.
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 M 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.
4.2. Main dimensions of the instrument
The following figure shows the main dimensions of the instrument.
