S210
Dual 1 Form A
Solid State Relay
The S210 is a single-pole, double-throw, normally open, SCR output device. The circuits are composed of one LED on the input side which
activates an optically coupled IC circuit on the output side - controlling the firing angle of two back-to-back SCRs. This circuit assures no
false triggering under most adverse conditions and a tight zero-volt window not exceeding 5V.

This solid state relay has been designed with a driver circuit that controls the operation of two back-to-back silicon controlled rectifiers (SCRs),
each responsible for one half of the AC cycle. If an AC signal is examined, the turn on, turn off and zero-volt switching can be seen. Figure 1
shows a typical 60 Hz, 120Vac signal with a corresponding relay input signal:
ZERO-VOLT SWITCHING
Figure 1 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 point is reached (Stage 2), SCR #1 (designated as the SCR which controls 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. Likewise, at the next zero cross (Stage 4), SCR #2 will turn off and SCR #1 conducts again.
Even though the input signal is terminated at Stage 5, the relay 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.
