You can get them combined with high-current devices to simplify the wiring ('Solid State Relays') though they tend to be a bit pricey. To be precise, it's driving a triac rather than an SCR. The circuit is a bit weird, (e.g. the resistor values are weird and the transistor would normally be placed between the opto-isolator and ground) though it's nothing compared to the auto-translated text, which often seems to be referring to a different circuit.
