2. For your safety
2.1. Authorized personnel
All operations described in this operating instructions
manual must be carried out only by trained and authorized
specialist personnel. For safety and warranty reasons, any
internal work on the instruments must be carried out only
by DATCON personnel (except setting DIL switches).
2.2. Appropriate use
The DT1364 is a two channel intrinsically safe NAMUR /
contact isolator. Detailed information on the application
range is available in chapter 3. Product description.
2.3. Warning about misuse
Inappropriate or incorrect use of the instrument can give
rise to application-specific hazards, or damage to system
components through incorrect mounting or adjustment.
2.4. General safety instructions
The DT1364 is a high-tech instrument requiring the strict
observance of standard regulations and guidelines.
The user must take note of the safety instructions in this
operating instructions manual, the country-specific
installation standards as well as all prevailing safety
regulations and accident prevention rules.
2.5. EU conformity
The DT1364 is in conformity with the provisions of the
following standards:
MSZ EN 60079-0:2013 (ATEX)
MSZ EN 60079-0:2013/A11:2014 (ATEX)
MSZ EN 60079-11:2012 (ATEX)
MSZ EN 61326-1:2013 (EMC)
MSZ EN 55011:2016 (EMC)
MSZ EN 55011:2016/A1:2017 (EMC)

3.2. Principle of operation
Area of application The DT1364 Intrinsically Safe NAMUR / Contact Isolator
is a two channel unit enable two safe area load to be
controlled by two proximity detector or switch, located in a
potentially explosive area of zone 0 or zone 1. The
instrument galvanic isolates the input, the output and the
power supply. The safe outputs are SPDT relay contacts.
The DT1364 has two built-in mode-control switches (one
per channel) for phase-reverse control (allows an alarm
condition to be signaled for either state of the sensors), for
on / off switch line monitoring (wire short, wire open). The
line fault detection opens the output in the event of short or
open-circuit lines: intended for use primarily with proximity
detectors. It can also be used with switches made to
resemble them electrically by adding two resistors, or
disabling by a switch if not required.

Operating principle
The instrument is powered from a 19-29 VDC supply
through a dual output high frequency DC-DC converter.
One output supplies channel 1 circuits, the other supplies
channel 2 circuits. The isolation and intrinsically-safe
segregation are provided by high isolation relays. Each
channel provide a 8.2 VDC supply voltage for the sensors
through a 1 kohm resistor. A multilevel comparator detects
the current consumption of the sensor (according with
NAMUR standard).
The levels are as follows:
> 2.1 mA ON (near) state
< 1.2 mA OFF (far) state
< 0.15 mA open circuit (wire broken) state
> 6 mA short circuit (wire short) state
The output relays are controlled by the comparator output
in conjunction of the states of mode switches.
Power supply The instrument works from a 19-29 VDC supply voltage.
The power consumption is 2.1 W.
3.3. Adjustment
The DT1364 operating modes can be set-up with two
internal three element DIL switches.

3.5. 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 DT1364 consist of environment-friendly,
recyclable cardboard is used to protect the instrument
against the impacts of normal stresses occurring during
transportation. The corragulated 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.
