  • Each circuit is rated for 2 amps. A fuse is hard-soldered which protects it.
  • Each relay draws about 10 milliamps when switched on.
  • Each relay has an LED wired to the circuit so that when the LED lights up when the relay is switched on.
Wiring the solid state relay. The LED doesn't switch off, when GPIO is cut? Do you know why?
