Photoelectric control circuit used in cotton feeder control

Published:2011/4/14 2:04:00 Author:Nicole | Keyword: photoelectric control, cotton machine control

Photoelectric control circuit used in cotton feeder control
When phototransistor T1 has illumination, it is low resistivity, then the potential in A point is falling, 3AX31 is conduction, relay is pull-in, to control the cotton feeder. 200μF capacitor and 3kΩ resistance form charge loop, to prevent the potential in A point from rising, it is a delay function, it can avoid too much actions of relay. 120Ω resistance is current negative feedback resistance, it is used to steady the work point of 3AX31. 2CP2 is used to protect 3AX31.
