Solid-state AC switch
Solid-state AC switch Designed for AC commutation and load management of low-voltage circuit is input to the detector optodriver zero phase, which provides galvanic isolation.
Simple diagram of Infrared barrier
This simple little circuit infrared barrier, triggered by crossing it. All farm consists of two parts – a transmitter and receiver.
Both are fed a constant stabilized voltage 12 … 16 V, current consumption is less than 20mA transmitter, receiver – 30mA.
