2Overview
2.1 Application
The devices of the K-System from Pepperl+Fuchs are used to transmit signals between field devices
and the process control system or control.
Devices with the "Ex" code in their type identifiers are suitable for connection to field devices in the
hazardous area. The field current circuits of these devices are intrinsically safe and are galvanically
isolated from the not intrinsically safe circuits. The devices thus represent an electrical isolation
between the hazardous area and the safe area within a system.
Devices without an "Ex" code can be used for signal transmission between field devices in the safe area
and the process control system or the control.

• You can connect resistance temperature sensors or thermocouples to
the input of the device (types: B, E, J, K, L, N, R, S, T). The device can also process a unit current
signal or a unit voltage signal.
• Two different limit values of the input signal can be monitored with the aid of the two relay outputs
on the device and parameters can be set freely for them.
• You can connect a PC for programming and diagnostics with PACTware™ (see section 6 and
section 7) on the device.
2.2 Versions

For primary explosion protection, that is, measures to avoid or restrict the
production of a dangerous, explosive atmosphere, please consult the
ATEX directive or the corresponding national provisions.
For secondary explosion protection, that is, measures to avoid the
ignition of a surrounding explosive atmosphere by electrical equipment,
Pepperl+Fuchs will gladly provide you with a copy of the "Ex-protection
manual" for a nominal fee.
Please pay particular attention to EN 60079-0, EN 60079-11, and
EN 60079-15 or the corresponding national provisions.
Pepperl+Fuchs also provides a seminar on the topic of explosion
protection.
5 Mounting and Connection
5.1 Mounting
284503 2015-09
The temperature t rip am plifier KFD2-GU-(E x)1 are co nstructed i n prote ction class IP20
and must therefore be protected from undesirable environmental conditions (water,
dust, small foreign objects).
The devices of the K-System from Pepperl+Fuchs can be mounted on a
35 mm top-hat rail corresponding to EN 60715. The devices must be snapped
onto the rail vertically, and never slanted or tipped to the side.
Further mounting alternatives, e. g. using the Power Rail, can be found in the
operating instructions for the K-System on our internet page
www.pepperl-fuchs.com/pa (under product search, enter *GU*).

5.2 Connection
The KF series' slip-off terminals significantly simplify connection
and construction of switching cabinets. They allow quick and
error-free exchange of the unit when service is needed.
The terminals can be screwed on, are self-opening, and have
generous connection room for a wire diameter of up to 2.5 mm²
and coded plugs, so that leads cannot be confused.

Mounting and Connection
The intrinsically safe field circuit is connected to the blue
terminals 1 to 6 of the KFD2-GU-Ex1. The circuit can be
directed with interface cable based on EN 60079-14 into
the area subject to the danger of explosion.
The non-intrinsically safe field circuit is connected to the
green terminals 1 to 6 of the KFD2-GU-1.
In both cases you can connect:
• a resistance temperature sensor Pt100 or Ni100
in 2-wire design (terminals 2 and 3)
in 3-wire design (terminals 1 to 3)
in 4-wire design (terminals 1 to 4)
• a thermocouple of type B, E, J, K, L, N, R, S, or T
(terminals 1 and 2). For an internal cold junction
compensation, you will need terminal K-CJC as an
accessory instead of the normal terminal 1 to 3.
• a source for a unit current signal of 0 mA ... 20 mA or 4
mA ... 20 mA (terminals 2 and 5)
• a source for a unit voltage signal 0 V ... 10 V (terminals
2 and 6)
The function of the green terminals 7 to 15 is as follows:
• terminals 7 to 9: relay 1
• terminals 10 to 12: relay 2
• terminals 14(+)/15(-): 24 V DC power supply (13 free)
For power supply via Power Rail, please refer to the

The following parameters can be set:
•Sensor:
Resistance temperature measurement sensor: Pt100, Ni 00
Thermocouples: T/C type B, T/C type E, T/C type J, T/C type K, T/C type L, T/C type N,
T/C type R, T/C type S, T/C type T
other: 0...10 V, 0...20 mA, 4...20 mA (NE43)
• Connection mode (for resistance temperature detectors only, see section 5.2):
2-wire
3-wire
4-wire
• Unit:
for resistance temperature measurement sensors and termocouples: °C or K
with selection of 0...10 V under sensor: fixed V
with selection of 0...20 mA or 4...20 mA (NE43) under sensor: fixed mA
The unit selected at this point will be used for all corresponding settings and displays in PACTwareTM.
• Cold junction compensation (for thermocouples only):
external (Reference temperature)
internal (K-CJC)
If you have selected Ext. ref. temp., you can enter the external reference temperature
(range of values: -100 °C to 100 °C)
For a internal Cold junction compensation, you require the K-CJC terminal block as an accessory
instead of the normal terminal 1 to 3 or 4 to 6 (see section 5.2).
• Lead Resistance: When connecting an RTD with 2 wire connection the lead resistance of the cabling
can be entered numerically if known.
• 2-Wire Calibration: When connecting an RTD with 2 wire connection the lead resistance of the
cabling can be calibrated if the resistance is unknown. For calibration the sensor must be jumpered.
• Sensor-breakage monitoring (for all types of sensors)
• Sensor-short-circuit monitoring (for resistance temperature detectors only)
• Cold junction sensor defective (for thermocouples)
• Range exceeded (for 0...10 V and 0...20 mA)
