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 DT1361 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 DT1361 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 DT1361 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 DT1361 Intrinsically Safe NAMUR / Contact Isolator
is a single channel unit enable one safe area load to be
controlled by a proximity detector or a 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 output is a SPDT relay contact.
The DT1361 has a built-in mode-control switch 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 DC-DC converter. The output supplies the input
circuit. The isolation and intrinsically-safe segregation are
provided by a high isolation relay. The input circuit provides
a 8.2 VDC supply voltage for the sensor 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 relay is controlled by the comparator output in
conjunction of the states of mode switch.
Power supply The instrument works from a 19-29 VDC supply voltage.
The power consumption is 0.6 W.
3.3. Adjustment
The DT1361 operating modes can be set-up with the
internal three element DIL switch.

3.4. Indicators
The following figure shows the indicators on the instruments
front:
1. “power” green indicator, indicates the power-on state of
the instrument.
2. red indicator, indicates the line fault state
3. yellow indicator, indicates the output active state
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 DT1361 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. Setting-up the operating modes
The operating modes can be set-up with the internal DIL
switch (SW1). To reach the DIL switch the instrument
housing shall be open.
