Example 2. Line-to-Neutral, Transformer-Isolated Coupling Circuit
Figure 4.2 presents a schematic for a line-to-neutral (L-N), transformer-isolated coupling circuit. Table 4.3 lists
component values and example suppliers/part numbers for coupling to AC mains with a nominal line voltage of
≤240VAC. This schematic can also be used for coupling to wiring other than AC mains with AC or DC voltages of
250V
RMS
or less or for coupling to an un-powered wire pair.
