Schedule
 
EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
 
Supply circuit

The segment coupler type KFD2-BR*-EX*.***, KLD2-PL*-EX*.***, KLD2-PR*-Ex*.IEC1 are used as associated apparatus for the supply of intrinsically safe electrical apparatus and for the transmission of electrical signals from the explosion hazardous area to the non explosion hazardous area and vice versa. The intrinsically safe output circuit corresponds to the FISCO model. The maximum permissible ambient temperature is 60°C.

Electrical data

Mains circuit

(terminals 59(+), 60(-)

and contacts 1(+), 2(-))

direct voltage                       U = 20 V – 35 V; approx. 7 W

maximum voltage                              U m = 253 V AC resp.

                                               U m = 125 V DC

KLD2-PR*-Ex*.IEC1

Data circuit

(terminals 40, 41, 42, 55, 56, 57 and contacts 3, 5)

for connection to an IEC61158-2 interface

maximum voltage                              U m = 60 V

 

KFD2-BR*-EX*.*** and KLD2-PL*-EX*.***

Data circuit

(terminals 40, 41, 42, 55, 56, 57 and contacts 3, 5)

for connection to a serial interface RS485

maximum voltage                              U m = 60 V

EQUIPMENT(continued):
 
Supply circuit

Output circuit

(terminals 3, 18(+)

and 2, 17(-))

 

in type of protection “Intrinsic Safety”               Ex ia IIC /IIB

Maximum values:

U o = 15 V

I o = 207,2 mA

P o = 1,93 W

R i = 190,4 Ω

 

output characteristic trapezoidal

for connection to fieldbus-systems according to the FISCO-model with the following characteristics:

 

All apparatus connected to the output circuit (fieldbus) must act as passive current sink (non-feeding). The effective internal capacitance and inductance of each apparatus must keep the following limits:

L i ≤ 10 µH

C i ≤ 5 nF

 

 

The line used for the fieldbus must keep the following ranges with regard to it’s reactances per unit length:

 

R’ = 15…150 Ω/km (loop resistance)

L’ = 0,4…1 mH/km

C’ = 80…200 nF/km (incl. a possibly existing shield),

C’ = C’strand/strand +0,5xC’strand/shield (if the bus circuit is floating)

resp.

C’ = C’strand/strand +C’strand/shield

(if the shield is connected to one pole of the supply unit)

 

A terminator, consisting of a capacitor up to 2,2 µF (incl. tolerance) in series to a resistor of 90…100 Ω, is permissible at the end of the line. This requires a separate examination certificate as a rule.

 

If the conditions mentioned are met, the maximum line length up to 1000 m is not limited with respect to safety technology.

Shield

(terminal 1, 16)

Only for connection to the line’s shield or the equipotential bonding respectively.

The intrinsically safe output circuit is safely electrically isolated from the mains circuit as well as the data circuit up to a peak value of the nominal voltage of 375 V.
