Interface Modules
TURCK's IM series of Isolating Intrinsically Safe Barriers is designed to be a simple and safe way to solve the
problems associated with the installation of equipment that is used in potentially explosive atmospheres.
TURCK's IM series utilizes the intrinsically safe concept that is universally accepted, easy to apply and the safest
way to install electronic measuring, monitoring and control equipment in potentially explosive atmospheres.
The IM series uses state of the art circuitry and the latest technology to produce an unsurpassed product that
provides the best explosion protection interfaces on the market.
The IM series of Intrinsically Safe Interface Devices is application specific: Each device is designed to work in a
specific application, be it analog input, analog output, discrete input, discrete output or others. The series was
designed to handle the vast majority of applications where instrumentation and control in potentially explosive
atmospheres is typically installed. A small number of interface devices will cover a large number of applications.
This is a huge benefit, as limiting the number of different types of interfaces can significantly reduce the number
of spares. Reducing the number of model variations of those spares makes replacement or expansion much
easier, while also consolidating stock and making inventory easier to manage.
Intrinsic safety has come of age with the introduction of the IM series of Intrinsically Safe Isolating Barriers, making
IS applications in potentially explosive atmospheres safe, simple and economically attractive.
Choosing an appropriate IM series Isolator is made simple with the help of this guide. The interface devices
outlined within this guide allow you to make the appropriate selection for the corresponding field devices or
connections with ease.

TURCK
Interface Technology
Isolation Switch Relays
For Use with NAMUR Proximity Sensors and Mechanical Switches
TURCK offers a wide range of isolating switch relays. These devices can serve various applications ranging from a
single dry contact switch input with a complimentary dry contact switch output, to four NAMUR proximity inputs
and four transistor outputs, while also providing open and short-circuit protection in addition to alarm
functionality.
Isolation switch relays may be used in general purpose applications, and most are certified for use in hazardous
(explosive atmospheres) areas by various approvals bodies. These devices carry U.S., Canadian and European
approvals that may be required in order to cover projects being engineered for use in locations throughout the
world. The devices share many common attributes, such as housings and removable terminal connectors. Most
are also available with the universal voltage (20-250 VAC/20-25 VDC) required to power the unit. All units have
the option for short-circuit and open-circuit (wire-break) protection: a simple series of switches that can be
manually configured by the user if the function is to be implemented. A resistor network (WM1 shown in Figure
1) is required to incorporate these functions when using a mechanical (dry contact) switch for the hazardous area
inputs.
The IM series of isolation switch relays is designed to handle the vast majority of applications where mechanical
switches or NAMUR proximity sensors are used. Short-circuit and open-circuit (wire-break) functions are
available for most devices. This function can be implemented by appropriately configuring the switches located
on the top of the units. NAMUR proximity switches have no special requirements in order to incorporate this
function, simply set the switches to the appropriate positions.

Interface Module
Application Guide
Dry contact (mechanical switches) however, require the use of a resistor network in order for the additional
functions to operate properly. The incorporation of a ready made resistor network module (WM1 see Figure 1) is
recommended.
This section highlights the devices and provides a simple approach for installing the various models available.
Examples of common applications are provided along with simple connection diagrams that allow any user to
easily and safely install these devices.
Typical and specific functions for each individual device are highlighted in the "Features" portion of the
specification pages. A handy pin-out reference chart is also provided for each device. Input and output common
configurations for use with NAMUR proximity sensors and dry contact mechanical switches, are also highlighted
in this section.
Common Input Configuration for Proximity Sensors
NAMUR 2-wire proximity sensors are specifically designed to work with TURCK isolation switch relays. No entity
calculations are required, as all NAMUR proximity sensors and associated apparatus with NAMUR inputs (TURCK
isolation switch relays) are designed to be 100% compatible without the requirement to calculate entity
parameters. These calculations are accounted for in the design of both the field devices (proximity sensors) and
the interfaces (barriers). All NAMUR proximity sensors are compatible with NAMUR interface devices in all
classified areas.
The 2-wire configuration is standardized so the blue wire is always negative and the brown wire is always positive.
Reversing these connections will not damage the device, however it will not function.
Connection diagrams for individual devices are shown in the product specification description pages.
Common Input Configurations for Dry Contact Mechanical Switches
Simple switch inputs are easily accommodated by the NAMUR input interface units. Switches are not required to
be approved as intrinsically safe devices. Simple switches are defined as "simple apparatus" by the national
electrical code as: (NEC 504-2)
A device that will neither generate nor store more than 1.2 V, 0.1 A, 25 mW, or 20 μ.
Using a simple switch does require the use of a resistor network (WM1) if the short-circuit and open-circuit
(wire-break) functions are not used. These functions are not required and can be disabled by simply switching
the function "OFF" using the configuration switches on the top of the units.

Interface Module
Application Guide
All IM1-xxx Modules are Equipped With:
Intrinsically Safe Field Terminals
This feature allows the use of any certified NAMUR sensor or dry contact mechanical switch (simple apparatus) to
be used in any area classification without risk of explosion.
Universal Input Voltage
This feature allows any power supply with an output of 20-250 VAC or 20-125 VDC to be used to power the
units. This provides extreme flexibility in the source power required to operate the units.
Removable "Keyed" Terminals
This feature allows easy wiring. The keyed connectors assure safe and accurate installation. Terminals can be
removed and wired without physically making the connections in tight quarters. Cable harnesses that incorporate
these connectors can actually be wired outside cabinets, and assembly is completed by plugging in the terminals
to the corresponding barrier. A bus power configuration is also available. That allows several barrier's power
connections to be bussed in a daisy-chain configuration, further reducing installation time and wiring.
Replacement of units when necessary is also simplified.
Short-circuit and Open-circuit Detection
This feature allows monitoring of field circuits for wire faults. The function is selectable and can be disabled if not
required or desired. NAMUR sensors need no accessory to provide the function. Dry contact mechanical
switches require a resistor network to properly function. The WM1 resistor network module will provide this
function, or a network of discrete resistors can be added by the user. Utilization of a common non-hazardous
area alarm circuit signifies a fault in the hazardous area wiring.
N.O./N.C. Configuration
This feature allows the input function to be selected as a normally open or normally closed output. Each channel
can be separately configured depending on module type.
Galvanic Isolation
This feature provides isolation between inputs, outputs and the power supply. In some cases, individual outputs
are also isolated from each other.
Switching Status and Power Indication LEDs
This feature provides a visual indication for the switching status of each channel. The green LED indicates that
the unit is powered. The dual color LEDs indicate switching (yellow) and fault status (red). A fault status on an
input disables the corresponding output relay.
Housing Sizes
The size depends on the number of channels. All 4-channel devices utilize the wider 27 mm housing, while the
1 and 2-channel devices are housed in the 18 mm style. Both are the same height, and can be mounted on a
DIN-rail or flush mounted on a panel.

Hazardous (Classified) Area
The hazardous area terminals of the IM series switch input isolators are suitable for use with mechanical switch or
NAMUR inputs in ALL area classifications.
Shown here is the common input configuration for a NAMUR proximity sensor. The wires are color coded and
blue is always the (-) terminal and brown is always the (+) terminal.
Open-circuit (wire-break) and short-circuit can be configured by the switch settings on the top of the unit, if the
unit is equipped with this function. No special conditions are required to incorporate the function when using
NAMUR proximity sensors.
Division/Zone 2 or Non-Hazardous Areas
IM units are certified to be mounted in a Division/Zone 2 area. Units must be housed in an appropriate
enclosure suitable for the environment in which they will be installed.
Explosion-proof or purged enclosures are not required for use in this area classification with the TURCK IM series.
Non-Hazardous (Non-classified) Area
Non-hazardous area terminals are designed to be connected to apparatus in a non-classified area.
The equipment may consist of alarm circuits, PLC or DCS controllers or other similar types of equipment.

Interface Technology
Analog Data Transmitters
Analog data transmitters are a selection of devices that allow the transmission of hazardous area analog signals to
a non-hazardous area as a direct one-to-one, or with a slight variation that is sometimes desired for specific
applications.
The Analog Isolating Transmitters can transfer 4/20 mA, 0/20 mA, 0-10 V or 2-10 V signals from a hazardous area
and repeat the signal in the non-hazardous area either as a current or a voltage signal; 2 current signals or a 2
channel one-to-one combination, depending on the module.
These devices offer a much requested and much desired mix of inputs and outputs that are sometimes difficult to
achieve with conventional intrinsically safe interface devices. Flexibility is a key feature of these devices, with the
option to convert from voltage to current or from current to voltage where required. The multi-channel device
also provides a compact high-density solution for applications where space is an issue.

Analog Data Transmitters
Functional Description:
This 1 channel intrinsically safe interface will receive either a 4/20 mA or 0/2-10 V signal from a hazardous area and repeat
the signal in the non-hazardous area as either a 0/20 mA or 4/20 mA signal reflecting the hazardous area input. It will drive a
non-hazardous area load of up to 500 Ω.
In switch position "1:1" the hazardous area inputs are reflected one-to-one in the non-hazardous area. In position "LZ" a
dead-zero signal (0-10 V or 0/20 mA ) input is reflected as a live-zero signal (4/20 mA) output.
Features:
• 1 channel analog data transfer/converter
• Choice of input signal voltage or current
• Choice of output signal voltage or current
• Short-circuit protected output

TURCK
Interface Technology
Analog Input Repeaters/Supplies
The analog input repeaters/supplies interfaces in this section are designed to work with the vast majority of analog
input field devices. Field devices can range from a simple 2-wire 4/20 mA transmitter to a 3-wire HART smart
device requiring the interface to provide operating power and a bi-directional path for the digital HART
information along with the 4/20 mA control signal. The analog input units will also accept a sourced signal from a
separately powered field device, or other source generated by an "IS" device in a hazardous area. The unit can
also be used to receive a sourced "IS" signal from a 4/20 mA driver with "IS" outputs in another non-hazardous
area. The "IS" driver/"IS" receiver combination render the cable connections intrinsically safe thus allowing the
driver/reciever cable to be used with other "IS" signals in multi-core cables or in an "IS" cable tray.
The analog input units versatality allows easy selection for most transmitter applications, thus reducing stock and
inventory further simplifying the selection process. The control system can also be configured to provide alarm
functions for certain states indicating the short or open-circuit conditions for the units.
Ease of installation is inherent when applying these devices.

Temperature measurement is a very common application, even in hazardous areas. The IM34 temperature
converting device provides advanced diagnostics, versatility and convenience in an easy-to-use device.
The IM34 will convert a 2, 3 or 4-wire RTD, mV signal, or T/C in a hazardous area, to an analog 4/20 mA signal in
a non-hazardous area. This pushbutton or software (FDT/DTM, free shareware) configurable unit is simple to use
and saves time and money on installations.
This diverse unit allows several different input types to be configured and used with common 4/20 mA analog
input control cards. Elimination of separate RTD, T/C and mV input cards may consolidate inventory, as well as
allow the use of off-the-shelf "Simple Apparatus" components in even the most explosive atmospheres; further
reducing costs for installation and maintenance.
Temperature measurement in hazardous areas has never been easier, or as safe, than this.

Adjustments
The device settings are accomplished with 4 rotary switches and 10
slide switches (IM34-12Ex-Ri:7 rotary switches and 13 slide
switches) located on the right side of the housing.
• High Temperature Value TH: the upper temperature range
value according to an output current of 20 mA is set with the
two rotary switches (1, 2). Rotary switch 2 serves to set
temperature values in increments of a hundred degrees celsius.
Switch 1 serves to set the temperature in steps of ten degrees.
Thus, the temperature values can be set in steps of 10 K.
(Example for switch position: 53 ⇒ 530°C). If the slide switch
S6 is in position 1, the temperature range is automatically
increased by a 1000°C to 1000-1990°C. Add a 1000°C to the
temperatue value adjusted with rotary switches 1 and 2.
(Examples for switch position: 53 ⇒ 1530°C; 00 ⇒ 1000°C).
• Low Temperature Value TL : the two rotary switches (3, 4)
serve to set the temperature which accords to an output current
of 0 or 4 mA (determined by slide switch S8). If slide switch S5
is in position 1, rotary switch number 4 is used to adjust the
temperature in hundreds, while switch 3 adjusts the tens place.
Adjustment takes place in a temperature range of 0 to +990°C
in increments of 10 K (e.g. rotary switch setting 23 accords to a
temperature of 230°C). If slide switch S5 is in position 0, rotary
switch 4 adjusts the negative tens places and rotary switch 3
adjusts the ones. Adjustments are possible in a temperature
range of -100 to -1°C in increments of 1 K. (Examples for rotary
switch position: 23 ⇒ -23°C; 00 ⇒ -100 °C).
• Switching Threshold for Relay
(IM34-12Ex-Ri only)
Rotary switch 5 = hundred degree values
Rotary switch 6 = ten degree values
Rotary switch 7 = one degree values
S11 and S12 = 1: add 1000°C to the adjusted value. S11 = 0:
the adjusted value is negative. The output mode is adjusted
with S13.

Parameterisation and Adjustments
The IM34... is parameterised and adjusted via the Device Type
Manager (see also "PACTware™ and devices DTM software
installation"). The TURCK adapter IM-PROG is needed to establish
the connection between the device and your PC.
For this it is necessary to connect the 3.5 mm connector to the
measuring amplifier (PCConnect) and the RS232 connector to the
serial interface of your PC. The following settings are available as
an entry or numerical setting via the DTM:
• Mode
Selection of the connection element: Pt/Ni100,
thermo-element, mV input and selection of line compensation.
The following settings depend on the selections made in the
"Mode" menu:
– Thermo-element
Type selection: E, J, K, N, R, S, T, L, B
– Connection Mode of Temperature Resistor
2, 3 or 4-wire connection technology
– Measuring Range
The measuring range is composed of the lower and upper
temperature value. After selecting the connecting type, the
measuring range is indicated in the lower section of the DTM.
These indications accord to the adjusted analogue output signal
of 0/4-20 mA. The lower temperature depends on the type of
thermoelement/temperature resistor and accords to an output
signal of 0/4 mA. The upper limit temperature also depends on
the type of thermo-element/temperature resistor. The adjusted
upper limit temperature accords to an analogue output signal of
20 mA.
– Output Signal
The selection comprises 0-20 mA, 4-20 mA signals. The
adjusted values correspond to the adjusted lower and upper
limit temperatures.
– Line Compensation
In case of 2-wire connections, the resistor can be adapted to the
connection cable. For this it is necessary to short the measuring
point.
The LEDs Pwr and flash alternately. If they start flashing
mutually line compensation has been carried out. Continue by
selecting another function and removing the short-circuit. If the
LED continues to flash, line compensation has not been
accomplished succesfully. Line compensation must also be
carried out if thermo-elements with external cold junction are
used.
– Error Current
Either 0 mA or >22 mA
– Switching Threshold (IM34-12Ex-CRi only)
Entry of a temperature value or a low voltage value at which the
limit value relay is activated.
Mounting and Installation
The connected apparatus (Ni100/Pt100, thermo-elements) must
meet the requirements for use in explosion hazardous areas (EN
60079-14). The device is suited for snap-on clamps for hat rail
mounting (EN 50022) or for screw panel mounting. Devices of the
same type may be mounted directly next to each other. It must be
ensured that heat is conducted away from the device. Mounting
and installation must be carried out in accordance with the
applicable regulations. The operator is responsible for compliance
with the regulations. The removeable terminal blocks are coded
and may only be plugged into the designated sockets. The coding
system may not be altered or damaged. The device must be
protected against dust, dirt, moisture and other environmental
influences as well as against strong electromagnetic emissions. It
should also be protected against the risks of mechanical damaging,
unauthorised access and incidental contact. All installations must be
carried out observing the regulations of EMC protection.

Important information on use of devices with "IS" circuits
This device is equipped with circuits featuring protection type
intrinsic safety for explosion protection per EN 50020 at terminals
1– 6 which are marked in blue. The intrinsically safe circuits are
approved by the authorised bodies for use in those countries to
which the approval applies.
For correct usage in explosion hazardous areas please observe
and follow the national regulations and directives strictly.
Following please find some guidelines referring to the frame-work
directive of the European Union 94/9/EC (ATEX 100a).
This device is classified as an associated apparatus which is
equipped with intrinsically safe and nonintrinsically safe circuits.
Therefore it may only be installed in the non-explosion hazardous
area in dry clean and well monitored locations. It is permitted to
connect intrinsically safe equipment to the intrinsically safe
connections of this device.
All electrical equipment must comply with the regulations applying
to use in the respective zone of the explosion hazardous area. If the
intrinsically safe circuits lead into explosion hazardous areas subject
to dust hazards, i.e. zone 20 or 21, it must be ensured that the
devices which are to be connected to these circuits, meet the
requirements of category 1D or 2D and feature an according
approval.
When interconnecting devices within such anassembly it is
required to keep and provide a proof of intrinsic safety (EN
60079-14). Once that intrinsically safe circuits have been
connected to the non-intrinsically safe circuit, it is not permitted to
use the device subsequently as intrinsically safe equipment. The
governing regulations cover installation of intrinsically safe circuits,
mounting to external connections, cable characteristics and cable
69
installation. Cables and terminals with intrinsically safe circuits
must be marked and separated from nonintrinsically safe circuits or
feature appropriate isolation (EN 60079-14). Please observe the
specified clearances between the intrinsically safe connections of
this device and the earthed components and connections of other
devices.
The approval expires if the device is repaired, modified or opened
by a person other than the manufacturer or an expert, unless the
device-specific instruction manual explicitly permits such
interventions.
Visible damages of the device’s housing (e. g. blackbrown
discolouration due to heat accumulation, perforation or
deformation) indicate a serious error and the device must be
turned off immediately. When using associated apparatus it is
required to check the connected intrinsically safe equipment too.
This inspection may only be carried out by an expert or the
manufacturer.
Operation of the device must conform to the data printed on the
side of the housing. Prior to initial set-up or after every alteration
of the interconnection assembly it must be assured that the relevant
regulations, directives and framework conditions are observed, that
operation is error-free and that all safety regulations are fulfilled.

Solenoid Driver/Discrete Output Isolators
These loop powered "IS" interface devices provide power for "IS" solenoids in a hazardous area to be actuated from a
controller in the non-hazardous area.
The IM72 solenoid drivers are uniquely designed devices that allow them to drive the vast majority of "IS" solenoids available
in today's marketplace with a single type of interface device. Gone are the days when a wide variety of isolators were
available to drive specific solenoids with specific requirements. A single device will now allow you to use a single model for
most applications, eliminating the need to do complicated and tedious calculations.
The design of these 1 and 2 channel devices make it extremely simple to choose the appropriate interface. Either choose a 1
channel or 2 channel interface, that's all there is to it. Stock can be significantly reduced, and installation and maintenance
made easier. With a single unit for most applications, the IM72 makes choosing the appropriate interface as easy as it gets.

AT TURCK, WE THINK
HAZARDOUS AREA
CONTROL SHOULD BE
A WHOLE LOT EASIER.
www.turck.com
With TURCK intrinsically safe devices:
• Use lower cost, less bulky standard
enclosures.
Designing safety into potentially explosive areas can be a
challenge. At TURCK, we’ve made the problem a whole
lot easier with our line of intrinsically safe sensors and
interface devices.
Rather than trying to build a fortress around the hazard, our advanced
technology simply prevents ignition by limiting the thermal and electrical
energy to the hazardous area. Not only is it technologically superior, it’s
also easier to engineer, install and maintain – saving you time and money.
TURCK controls have proven themselves in the petro-chemical industry
and meet Factory Mutual requirements for Class I, Class II and Class III,
Division 1 and Division 2 environments. They easily interface to PLCs,
and can provide advanced intelligence to monitor speed, temperature,
pressure and other variables.
• Eliminate most cable seals and
explosion-proof conduit.
• Easily modify your system.
• Test your system live (hot).
FM approved for Class I, II and III,
Divisions 1 and 2.
