1.Q: Would you like to make multiphase relay?
A: OPTO22 only manufactures single-phase SSR. If multiphase operation is required, one relay is used for each phase. Due to the limitation of semiconductor type used by SSR, it is not practical to manufacture multiphase SSR. However, multiphase operation can be achieved by using multiple relays.
2.Q: What are the restrictions on Using SSR?
A: Compared with mechanical relays, SSR has very few limitations. First, because SSR is semiconductor based, it cannot be turned on all the way or off. This means that the relay is in the "on" state, and the relay still has internal resistance when there is current, which makes the relay warm. When in the off state, the relay still has a small leakage current, usually a few ma. Current leakage can be used to keep some loads from shutting down, especially when high impedance is high. In addition, SSR is very sensitive to voltage transients, although the relays of OPTO22 have excellent transient protection, and the performance will be damaged or reduced if the relay is subjected to sufficient times of impact. This makes SSR not ideal when it is used to drive large inductive electromechanical loads, such as some solenoids or motors. SSR must not be applied to certain conditions, such as safety power switch, because even in off state, leakage current exists. Leakage current through SSR exi
3.Q: What are the advantages of using SSR compared with mechanical relays?
A: In many applications, it is necessary to switch power elements (from a few watts to several kilowatts) very quickly. A good example is the control of heater elements in the temperature control system. The heating of input system is adjusted by wide pulse amplitude modulation, and the heating element with fixed power is switched periodically from seconds to minutes. Mechanical relays have limited switching times because their components are broken after tens of thousands of times. SSR has no such problems. If applied properly, it can run indefinitely.
