Schematic · SSR
What it represents
A solid-state relay switches an output through semiconductor circuitry in response to a control input. Control isolation, output type and leakage depend on the chosen product.
How to read it
- Distinguish the low-power input terminals from the load-side output terminals.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- Name output AC or DC type
- State input operating range
- Reference leakage and load limits
A distinction that matters
An SSR has no ordinary mechanical contact gap and must not be treated as a disconnector.
