FISCO Rules The FISCO Concept allows the interconnection of intrinsically safe apparatus to associated apparatus not specifically examined in such combination. The criterion for such interconnection is that the voltage (Ui), the current (Ii) and the power (Pi) which intrinsically safe apparatus can receive and remain intrinsically safe, considering faults, must be equal or greater than the voltage (Uo, Voc or Vt), the current (Io, Isc or It) and the power (Po) which can be provided by the associated apparatus (supply unit). In addition, the maximum unprotected residual capacitance (Ci) and inductance (Li) of each apparatus (other than terminators) connected to the Fieldbus must be less than or equal to 5 nF and 10 μH respectively. In each I.S. Fieldbus segment only one active source, normally the associated apparatus, is allowed to provide the necessary power for the Fieldbus system. The allowed voltage (Uo, Voc or Vt) of the associated apparatus used to supply the bus cable must be limited to the range of 14 V d.c. to 17.5 V d.c. All other equipment connected to the bus cable has to be passive, meaning that the apparatus is not allowed to provide energy to the system, except a leakage current of 50 μA for each connected device. Separately powered equipment needs galvanic isolation to ensure the intrinsically safe Fieldbus circuit remains passive. The cable used to interconnect the devices needs to comply with the following parameters: Loop resistance R': 15....150 Ω/km Inductance per unit length L': 0.4....1 mH/km Capacitance per unit length C': 45....200 nF/km C' = C' line/line + 0.5 C' line/screen, if both lines are floating or C' = C' line/line + C'line/screen, if the screen is connected to one line. Length of spur cable: max. 60 m Length of trunk cable: max. 1 km in IIC and 5 km in IIB Length of splice: max = 1 m Terminators At the end of each trunk cable an FM Approved line terminator with the following parameters is suitable: R = 90...100 Ω C = 0 ....2.2 μF

FNICO Rules The FNICO Concept allows the interconnection of nonincendive field wiring apparatus to associated nonincendive field wiring apparatus not specifically examined in such combination. The criterion for such interconnection is that the voltage (Vmax), the current (Imax) and the power (Pmax), which nonincendive field wiring apparatus can receive and remain nonincendive, must be equal or greater than the voltage (Uo, Voc or Vt), the current (Io, Isc or It) and the power (Po) which can be provided by the associated nonincendive field wiring apparatus (supply unit). In addition the maximum unprotected residual capacitance (Ci) and inductance (Li) of each apparatus (other than terminators) connected to the Fieldbus must be less than or equal to 5 nF and 20 μH respectively. In each N.I. Fieldbus segment only one active source, normally the associated nonincendive field wiring apparatus, is allowed to provide the necessary power for the Fieldbus system. The allowed voltage (Uo, Voc or Vt) of the associated nonincendive field wiring apparatus used to supply the bus cable must be limited to the range 14 V d.c. to 17.5 V d.c. All other equipment connected to the bus cable has to be passive, meaning that the apparatus is not allowed to provide energy to the system, except a leakage current of 50 μA for each connected device. Separately powered equipment needs galvanic isolation to ensure the nonincendive field wiring Fieldbus circuit remains passive. The cable used to interconnect the devices needs to comply with the following parameters: Loop resistance R': 15....150 Ω/km Inductance per unit length L': 0.4....1 mH/km Capacitance per unit length C': 45....200 nF/km C' = C' line/line + 0.5 C' line/screen, if both lines are floating or C' = C' line/line + C'line/screen, if the screen is connected to one line. Length of spur cable: max. 60 m Length of trunk cable: max. 1 km in IIC and 5 km in IIB Length of splice: max = 1 m Terminators At the end of each trunk cable an FM Approved line terminator with the following parameters is suitable: R = 90...100 Ω C = 0 ....2.2 μF

The load resistance of pulse output should be used to 1kΩ, 2W.If no translation of the pulse output possible by the cable length or the frequency of the pluse output,the load resistance should be selected by calculation as shown below.

Example of CEV cable capacitance 0.1µF/km

WhereE = Supply voltage (V) f = Frequency of pulse output (kHz)R = Value of load resistance (kΩ)

C = Cable capacitance (µF) P = Power ratio of the load resistance (mW)
