A Solid state relay is defined as a relay that uses voltage to change the state of the relay. Apply 12 or 24 VDC to the relay control input and the output relay changes state

A form C relay is like our accessory switches. It has an output with three wires, COM, NC, and NO

The form C relay usually has something internal triggering the relay so you are not sending voltage to control inputs to change the output state of the relay.

A solid-state relay uses voltage to change the state of the relay. Applying 12 or 24 VDC to the relay control input will trigger it to change state.
