opto isolator relay driver

Some readers may think I don't like ICs.
You can see the "large" black device above and to garage door manual lock the left of the lit LED.
See Horowitz and Hill,.Relay Operation, when a voltage is applied zoom gfx 5 patch to the coil, a current passes through it and this creates a magnetic circuit which includes the core, armature and the yoke.29 To date, Vactrols activated by pressing the stompbox pedal are ubiquitous in the music industry.20 In double mold designs the space between the silicone blob inner mold and the outer shell outer mold is filled with dark dielectric compound with a matched coefficient of thermal expansion.While, " digitalWrite(13, high " turns off the bulb.
Electronic Design, July 24, 2000.
Burr-Brown introduced a distinct class of capacitive-coupled analog isolation amplifiers in the 1980s.
Relay driver circuit To drive the relay from a low power signal a transistor is often used to switch the relay.
This configuration refers to optocouplers enclosed in a dark container wherein the source and sensor are facing each other.
