1.6 Intended Use
The devices are only approved for appropriate and intended use. Ignoring these instructions
will void any warranty and absolve the manufacturer from any liability.
The device must only be operated in the ambient temperature range and at the relative
humidity (non-condensing) specified.
The devices are used in C&I technology for the galvanic isolation of C&I signals such as
20 mA and 10 V standard signals or alternatively for adapting or standardizing signals.
Devices that incorporate intrinsically safe circuit are used for operating intrinsically safe field
devices in hazardous areas.

1.7 Improper Use
Protection of the operating personnel and the overall system is not ensured if the product is
not being used according to its intended purpose.
The equipment is not suitable for isolating signals in high current applications unless this is
noted separately in the corresponding datasheet.
1.8 Mounting/Installation
Prior to mounting, installation, and commissioning of the device you should make yourself
familiar with the device and carefully read the instruction manual.
The device must not be installed at locations where corrosive vapors may be present.
The devices fulfill a degree of protection IP 20 according to IEC/EN 60529.
The devices are designed for use in pollution degree 2 and overvoltage category II as per
IEC/EN 60664-1.
If used in areas with higher pollution degree, the devices need to be protected accordingly.
Only use power supplies that provide protection against direct contact (e. g. SELV or PELV)
for the connection to power feed modules.
Observe the tightening torque of the terminal screws.
The installation instructions in accordance with IEC/EN 60079-14 must be observed.
Intrinsically safe circuits of associated apparatus (installed in safe areas) can be led into
hazardous areas, whereby special attention must be paid to maintain separation distances
to all non-intrinsically safe circuits according to the requirements in IEC/EN 60079-14.
All separation distances between two adjacent intrinsically safe circuits need to be observed
in accordance with IEC/EN 60079-14.
If "Ex i" protected circuits (intrinsically safe) were operated with non-intrinsically safe circuits,
they must no longer be used as "Ex i" protected circuits.

EN
The respective peak values of the field device and the associated apparatus with regard to
explosion protection should be considered when connecting intrinsically safe field devices
with intrinsically safe circuits of associated apparatus (verification of intrinsic safety). Make
sure to observe IEC/EN 60079-14 and IEC/EN 60079-25.
If more channels of one device are connected in parallel, make sure the parallel connection
is made directly at the terminals of the device. When verifying the intrinsic safety, the
maximum values for the parallel connection must be considered.
1.9 Operation, Maintenance, Repair
The devices must not be repaired, changed or manipulated. If there is a defect, the product
must always be replaced with an original device.
1.10 Delivery, Transport, Disposal
Check the packaging and contents for damage.
Check if you have received every item and if the items received are the ones you ordered.
Keep the original packaging. Always store and transport the device in the original packaging.
Always store the device in a clean and dry environment. The permitted storage temperature
(see data sheet) must be considered.
Disposing of devices, packaging material, and possibly contained batteries must be in
compliance with the applicable laws and guidelines of the respective country.

2 Product Specifications
2.1 Function
The HART Loop Converter is an isolated barrier suitable for intrinsically safe applications.
The device supplies field devices and can be connected in parallel to existing HART circuits.
The device analyzes up to four HART variables (PV, SV, TV, QV). Three HART variables
can be transformed into varying current signals from these four HART variables. These
signals are used to display the values via the analog inputs of the process control system.
The device is easily configured by the use of keypad or with the PACTware configuration
software.
KFD2-HLC-Ex1.D.2W
In addition to the current outputs, the device has two changeover contacts. These
changeover contacts can be programmed so that the changeover contacts function as trip
values for the HART variables.
KFD2-HLC-Ex1.D.4S
In addition to the current outputs, the device has four NO contacts. These NO contacts can
be programmed so that the NO contacts function as trip values for the HART variables.

3 Installation
3.1 DIN Mounting Rail
The devices are mounted on a 35 mm DIN mounting rail according to EN 60715.
Figure 3.1 Example: DIN mounting rail UPR-MR (35 mm x 15 mm)
3.2 Power Rail
To reduce wiring and installation costs, Power Rail is the optimum solution. The Power Rail
is a DIN mounting rail with plastic insert, that delivers power to the devices (24 V DC) and
transfers bus signals and a collective error message.
The Power Rail is factory-equipped with cover and end caps. These parts cover empty and
open segments of the Power Rail. Thus, the Power Rail is protected from contamination.
Additionally the cover and end caps prevent that electrically conductive parts come in
contact with the Power Rail.

3.3 Mounting
Mounting the Isolated Barrier
Snap the device onto the DIN mounting rail in a vertical downward movement. See figure
below.
Mounting the Terminal Blocks
The insulation of the removable terminal blocks protect against direct contact. If you replace
the terminal blocks, observe the rated insulation voltage. If the rated voltage greater than
50 V AC, proceed as follows:
1. Switch off the voltage.
2. Connect the terminal blocks or disconnect the terminal blocks.
CORRECT: Device snapped on vertically. INCORRECT: Device snapped on from the side.
Can damage the contacts and cause the device to fail.

3.4 Connection
The removable terminal blocks simplify connection and control cabinet construction
significantly. These terminal blocks offer adequate space for the connection of leads with
core cross-sections of up to 2.5 mm² (14 AWG). The terminal blocks are coded with red
coding pins so misconnection of terminal blocks are eliminated.
3.4.1 Input Connection (field circuit)
Connecting the Field Circuit
1. Connect the field circuit to the blue terminals.
2. Observe the tightening torque of the terminal screws. The tightening torque is
0.5 Nm ... 0.6 Nm.
The intrinsically safe field circuit may be routed in the hazardous area with connection lines
in accordance with DIN EN 60079-14. You can connect the following field devices:
1. any separately supplied HART current circuit with transmitter or positioner connected in
parallel
Connection to terminals 2 and 3
2. a HART-capable active current source, e. g., a separately supplied HART measuring
transmitter
Connection to terminals 2 and 3 with bridge between terminals 5 and 6
3. a 2-wire HART measuring transmitter, e. g., HART measuring transmitter with an analog
output signal of 4 mA ... 20 mA
The HART measuring transmitter is supplied by the isolated barrier
Connection to terminals 1 and 3 with bridge between terminals 4 and 5
