Engineering limitation: This application only performs preliminary entity-parameter screening for one independent power source and one field device per loop. Multi-source circuits, FISCO, special control drawings, cable fault analysis, EPL, gas/temperature suitability, installation and all certificate conditions require separate assessment.

Engineering document review

Source and field-device certificates, channel settings and special conditions checked. Area classification, EPL, temperature class, cable installation and segregation assessed separately. This is an independent one-source / one-device circuit compatible with entity screening.

Calculation basis and limitations

Uo ≤ Ui; Io ≤ Ii; Po ≤ Pi; ΣC = Ci + (cable length × pF/m ÷ 1,000) ≤ Co*; ΣL = Li ÷ 1,000 + (cable length × µH/m ÷ 1,000) ≤ Lo*. Co* and Lo* are adjusted limits where the applicable linear-source mixed-reactance 50% rule is triggered.

Numerical results only: use actual certification / control drawings and selected gas group. This table alone does not establish installation compliance, Ex protection suitability or a full IEC 60079-25 descriptive system document.
