There are two main areas of the solid state relay:
SSR input: There are a number of aspects of the input circuit to consider as the input LED needs to operate under the required input conditions:
Input drive level: The input circuit needs to ensure that the optical transmitter, i.e. LED is able to operate wit the specified drive level. This normally requires the inclusion of a current limiting resistor and any other electronic components to ensure the LED lights sufficiently with the incoming signal. Solid state relays are available that operate with input voltages of anywhere from a few volts upwards.
DC or AC input: If the SSR is intended for operation with a DC input then it can operate with a minimum of additional electronic components - possibly just a current limiting resistor. If AC operation is intended, then a rectifier and normally a bridge rectifier is used to rectify the input signal so that the LED is only driven with a signal of the correct polarity. The LED light will pulse with the alternating waveform - twice the frequency if a bridge rectifier is used. This bridge rectifier can be incorporated as part of the solid state relay, or possibly added externally.
SSR output: The output side of the solid state relay also requires understanding as there can be a number of additional electronic components beyond the basic photo-sensitive switching device.
A variety of different devices can be used for the output of solid state relays: transistors, thyristors / SCRs, MOSFETs and triacs. The device type determines many of the characteristics of the SSR.
If the output is a single transistor, FET or thyristor / SCR then this means that this SSR can only conduct in one direction and can only be used for controlling DC loads. A triac or two thyristors / SCRs in the output are generally required for AC operation - paired MOSFETs are also sometimes used.
The specified maximum output ranges for solid state relays can range from a few volts up to hundreds of volts AC or DC and the current levels that can be carried can be up to tens or even hundreds of amps according tot he specification of the particular device.
