Intrinsic Definition & Meaning - Merriam-Webster

WebAn intrinsically safe barrier relay, for example, may be used to interface with the hazardous area. Zener barriers consist of a simple network of diodes (Zener, for example) to clamp the voltage, a fuse to protect the Zener diodes and the entire network against faults, and resistors to limit the current output. WebAssociated Apparatus is generally thought of as a stand-alone zone barrier or isolation interface (known colloquially as the barrier) but it applies to any equipment with intrinsic safety and non-intrinsic safety terminals as the barrier may be built in to other equipment e.g. distributed I/O cards or output from an alternatively protected Hazardous area device …
