In contrast with electromechanical relays, the subcomponents in an SSRs are entirely electronic:

1. An SSR’s input circuit (like the coil of an electromechanical relay) connects to a system control. As voltage entering the SSR changes — 3 to 32 Vdc is common — it prompts the input circuit to act. In one common variation, the circuit activates upon application of any in-range voltage exceeding the relay’s pickup voltage value … and deactivates upon reduction of input to below the relay’s dropout voltage value.

2. An SSR’s coupling communicates energization and de-energization commands to the relay output — acting as the go-between between the input and output circuits. Note that this portion of an SSR is specially engineered to ensure the input circuit interfaces with the output circuit in a galvanically isolated way … so that high-power (output) load current is segregated by the relay’s coupling section. That reliably prevents load current from flowing to the relay input — even during system failure.

Various technologies are used for the coupling portion of an SSR:

The most common type, photocoupler SSRs, uses an LED or infrared light source on the input circuit to communicate with a photosensitive semiconductor on the output switch side. In contrast, transformer-coupled SSRs use a dc-ac converter to generate output that magnetically couples to the output via a low-power transformer.

3. Next an SSR’s trigger or drive circuit connects one of several designs taking the form of a:

• Silicon-controlled rectifier (SCR) for high-speed switching of (usually) short-duration “on” periods
• Back-to-back thyristor called a triac — short for triode for alternating current
• Metal-oxide semiconductor field-effect transistor (MOSFET) or Darlington transistor (for dc)
• Insulated-gate bipolar transistor (IGBT) for dc

Here, zero-switching operation — the most common for SSRs — as well as peak switching, dc switching, and instant-on switching are all options to tailor the relay action to the type of load the system drives. For example, analog switching uses a synchronizing circuit to make output voltage track input voltage — and allow a wide variety of possible output voltages within the SSR’s allowable range. These excel in soft-start designs to drive electric motors.

4. Beyond that, an SSR’s output (power) circuit connects to the load being controlled. Past the switch it may also include a snubber circuit (in some cases, a reverse-connected diode) or a zero-crossing detector to reduce spikes and transients and electromagnetic interference (EMI) during switching. That’s an issue because SSRs switch load current through attached inductive loads — and (according to Faraday’s law) current interruption induces voltage rise. Any such rise across the SSR exceeding the maximum ratings may cause damage.
