Entity Concept & NI Field Circuit Parameters
The Transmitter must be installed according to National Electrical Code (ANSI-NFPA 70). Equipment approved for intrinsic safety may be connected to barriers based on the ENTITY CONCEPT. The intrinsically safe devices must not be a source of power. The maximum voltage, current, and power the device can receive must be equal to or greater than what the barrier delivers. Capacitance (Ci) and inductance (Li) of the device plus wiring must be less than the barrier's capacitance (Ca) and inductance (La).
