Allowable Inductance/Capacitance for Intrinsically Safe External Wiring

Keep the inductance (Lw) and capacitance (Cw) for the external wiring in the intrinsically safe circuit as shown below:

Lw

≤ Lo – Li, Cw ≤ Co – Ci

where Lo is the maximum external inductance, Li is the internal inductance, Co is the maximum external capacitance, and Ci

is the internal capacitance.
