ABSTRACT:
An isolator, such as a common-mode-reactor, and power-conditioner network is utilized to provide at least one of adequate segment impedance, cross-talk or adequate high-frequency-interference attenuation on, or between, participating segments. The participating segments comprise adequate power conditioning, and are supplied by an isolated or non-isolated common power supply. At least one of the segments may have one of two poles in resistive and/or capacitive and/or inductive contact to ground, as well as having one of the segments, in resistive and/or capacitive and/or inductive contact to another of one of two poles of other segments. The power-condition and common-mode inductor provide adequate two-wire Fieldbus communication impedance, by use of series passive reactance, where each reactor may comprise one, or more, separate reactors, intersected and/or shunted by one, or more, n-order passive dampers, having damping characteristics adequate to curtail provoked signal bias and/or jitter and/or distortion and/or resonance using a minimal amount of series-resistance.
