• Electrical data of the EXA PH202S-F:- Supply circuit: Vmax=17,5 V; Imax=380 mA; Pi=5,32 W; Ci=737 pF; Li=2.6 µH.- Sensor input circuit: Vt=14.4 V; It=32.3 mA; Ca=600 nF; La=36 mH
• Any FM Approved FISCO barrier may be used that meets the following requirements:Voc or Vt ≤ 17,5 V; Ioc or It ≤ 380 mA; Poc or Pt ≤ 5,32 WWhen installing this equipment, follow the manufacturer’s installation drawing.Installation should be in accordance with ANSI/ISA RP 12.06.01 "Installation of Intrinsically Safe Systems for Hazardous (Classified) Locations"and the National Electrical Code (ANSI/NFPA 70).Associated apparatus connected to the FISCO barrier must not use or generate more than 250 Vrms or Vdc.
• Resistance between FISCO Intrinsically Safe Ground and earth ground must be less than 1.0 Ω.• The FISCO concept allows the interconnection of several I.S. apparatus not specifically examined in such combination. The criterion for such
interconnection is that the voltage (Vmax), the current (Imax) and the power (Pi) which I.S. apparatus can receive and remain intrinsically safe,considering faults, must be equal to or greater that the voltage (Voc, Vt), the current (Ioc, It) and the power (Poc, Pt) which can be providede bythe FM approved FISCO barrier. In addition, the maximum unprotected residual capacitance (Ci) and inductance (Li) of each apparatus (otherthan the terminator) connected to the Fieldbus must be less than or equal to 5nF and 10 µH respectively.
• In each I.S. Fieldbus segment only one active source, normally the FM Approved FISCO barrier, is allowed to provide the necessary power forthe Fieldbus system. All other equipment connected to the bus cable has to be passive (not providing energy to the system), except to a leak-age current of 50µA for each connected device. Seperately powered equipment needs a galvanic isolation to insure that the I.S. Fieldbus circuitremains passive.
• The cable used to interconnect the devices needs to comply with the following parameters:Loop resistance R’: 15 to 150 Ω/km; Inductance per unit length L’: 0.4 to 1 mH/kmCapacitance per unit length C’: 80 to 200 nF/km(C’ = C’ line/line + 0.5 C’ line/screen if both line are floating)(C’ = C’ line/line + C’ line/screen if the screen is connected to one line)Length of spur cable: max. 30 mtr.Length of trunk cable: max. 1 kmLength of splice : max. 1 mtr.
WARNING- Substitution of components may impair Intrinsic Safety- To prevent ignition of flammable or combustible atmospheres, disconnect power before servicing or read, understand and adhere to the
manufacturer’s’live maintenance procedures.

• Any FM Approved FISCO barrier may be used that meets the following requirements:Voc or Vt ≤ 17,5 V; Ioc or It ≤ 380 mA; Poc or Pt ≤ 5,32 WWhen installing this equipment, follow the manufacturer’s installation drawing.Installation should be in accordance with ANSI/ISA RP 12.06.01 "Installation of Intrinsically Safe Systems for Hazardous (Classified) Locations"and the National Electrical Code (ANSI/NFPA 70).Associated apparatus connected to the FISCO barrier must not use or generate more than 250 Vrms or Vdc.
• Resistance between FISCO Intrinsically Safe Ground and earth ground must be less than 1.0 Ω.• The FISCO concept allows the interconnection of several I.S. apparatus not specifically examined in such combination. The criterion for such
interconnection is that the voltage (Vmax), the current (Imax) and the power (Pi) which I.S. apparatus can receive and remain intrinsically safe,considering faults, must be equal to or greater that the voltage (Voc, Vt), the current (Ioc, It) and the power (Poc, Pt) which can be providede bythe FM approved FISCO barrier. In addition, the maximum unprotected residual capacitance (Ci) and inductance (Li) of each apparatus (otherthan the terminator) connected to the Fieldbus must be less than or equal to 5nF and 10 µH respectively.
• In each I.S. Fieldbus segment only one active source, normally the FM Approved FISCO barrier, is allowed to provide the necessary power forthe Fieldbus system. All other equipment connected to the bus cable has to be passive (not providing energy to the system), except to a leak-age current of 50µA for each connected device. Seperately powered equipment needs a galvanic isolation to insure that the I.S. Fieldbus circuitremains passive.
• The cable used to interconnect the devices needs to comply with the following parameters:Loop resistance R’: 15 to 150 Ω/km; Inductance per unit length L’: 0,4 to 1 mH/kmCapacitance per unit length C’: 80 to 200 nF/km(C’ = C’ line/line + 0,5 C’ line/screen if both line are floating)(C’ = C’ line/line + C’ line/screen if the screen is connected to one line)Length of spur cable: max. 30 mtr.Length of trunk cable: max. 1 kmLength of splice : max. 1 mtr.

• Any FM Approved FISCO barrier may be used that meets the following requirements:Voc or Vt ≤ 17,5 V; Ioc or It ≤ 380 mA; Poc or Pt ≤ 5,32 WWhen installing this equipment, follow the manufacturer’s installation drawing.Installation should be in accordance with ANSI/ISA RP 12.06.01 "Installation of Intrinsically Safe Systems for Hazardous (Classified) Locations"and the National Electrical Code (ANSI/NFPA 70).Associated apparatus connected to the FISCO barrier must not use or generate more than 250 Vrms or Vdc.
• Resistance between FISCO Intrinsically Safe Ground and earth ground must be less than 1.0 Ω.• The FISCO concept allows the interconnection of several I.S. apparatus not specifically examined in such combination. The criterion for such
interconnection is that the voltage (Vmax), the current (Imax) and the power (Pi) which I.S. apparatus can receive and remain intrinsically safe,considering faults, must be equal to or greater that the voltage (Voc, Vt), the current (Ioc, It) and the power (Poc, Pt) which can be providede bythe FM approved FISCO barrier. In addition, the maximum unprotected residual capacitance (Ci) and inductance (Li) of each apparatus (otherthan the terminator) 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 FM Approved FISCO barrier, is allowed to provide the necessary power forthe Fieldbus system. All other equipment connected to the bus cable has to be passive (not providing energy to the system), except to a leak-age current of 50µA for each connected device. Seperately powered equipment needs a galvanic isolation to insure that the I.S. Fieldbus circuitremains passive.
• The cable used to interconnect the devices needs to comply with the following parameters:Loop resistance R’: 15 to 150 Ω/km; Inductance per unit length L’: 0,4 to 1 mH/kmCapacitance per unit length C’: 80 to 200 nF/km(C’ = C’ line/line + 0,5 C’ line/screen if both line are floating)(C’ = C’ line/line + C’ line/screen if the screen is connected to one line)Length of spur cable: max. 30 mtr.Length of trunk cable: max. 1 kmLength of splice : max. 1 mtr.
