Temperature Trip Amplifier KFD2-GU-(Ex)1
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
"Interface Technology" catalog of Fuchs.
For a detailed account of the terminal assignments,
please refer to the data sheet.
