32、on.Optical Isolator: The optical isolator in a SSR provides isolation between the input circuitry / control system, and the output circuit connected to the AC mains. The type of optical isolator used in the relay may also determine whether it is a zero-crossing or random-fire output. Trigger Circuit

33、: This processes the input signal and switches the output state of the SSR. The trigger circuit may be internal or external to the optical-isolator.Switching Circuit: This is the portion of the SSR that switches the power to the load. It usually consists of a transistor, SCR, or FET in a DC applicat

34、ion, or a triac, alternistor, or back-to-back SCR in an AC application.Protection Circuit: Many applications require some form of electrical protection to prevent the SSR from being damaged in the application, or from mis-firing due to environmental conditions.
