Abstract

An intrinsically safe circuit, which includes a voltage source, a Zener diode (106), a transistor (108), a switching element (109), one or more resistors (110,107,105), and a current limiting stage (114-118). According to this aspect, the intrinsically safe circuit may be configured such that an over-voltage threshold is determined by a voltage across the Zener diode, a base-emitter voltage of the transistor, and a voltage across the one or more resistors.
