Abstract:
A solid-state relay utilizing a light-emitting diode to transmit optical energy steadily to a photo-sensitive solid-state device to control the conductivity of solid -state elements. A relatively low power source of AC or DC can be used to operate photo-sensitive uni-junction transistor or a pair of lightactivated silicon-controlled rectifiers.
