If an AC signal is examined, the turn on, turn off and zero-volt switch ing can be seen. Figure 3 shows a typical 60 HZ, 120VAC signal with a corresponding relay input signal: Figure 3 shows the sequence of zero-volt switching operation. At Stage 1, an input signal is applied to the relay. The relay will not turn on until the threshold voltage of 5V is reached. Once this poi nt is reached (Stage 2), SCR #1 ( designated as the SCR which con trols positive AC voltage) turns on. However, SCR #1 only conducts for an instant, as the cycle quickly crosses zero. At this point (Stage 3), SCR #1 will turn off and SCR #2 (negative AC voltage) turns on. Li kewise, at the next zero cross (Stage 4), SCR #2 will turn o ff and SCR #1 conducts again. Even though the input signal is terminated at Stage 5, the rela y will continue to conduct (typical SCR behavior) until Stage 6, when SCR #1 crosses zero and ceases to conduct. Please note that turn on can likewise begin on the negative phase of the AC cycle with a -5V threshold, though only the positive phase is shown here.
