The invention relates to a cycle timing controller. The controller is composed of 12V DC power supply, timer circuit, output level amplification circuit and relay control circuit. The timer circuit is composed of oscillation circuit, reset circuit and 10 level output ports. Most of the common timers can only set a time to control the on or off of electrical appliances. Some control objects need periodic intermittent work, such as: exhaust fans in the kitchen, neon sign advertisements or industrial equipment, etc. It needs to be closed regularly, and the timer with only a single timing function is incompetent. The cycle timing controller circuit of the present invention can solve the control problem of the above electric appliances. The controller has a simple circuit principle and reliable working performance. It can properly adjust the parameters of resistance and capacitance in the oscillation circuit of the 14-stage binary counter integrated circuit IC1 in the circuit, or change the control line connected to the corresponding output terminal of the integrated circuit IC1 (Q4~Q14 ), you can get different cycle waiting time and action execution time.
Description
technical field [0001] The invention belongs to the field of electronic technology, and relates to a cycle timing controller. Background technique [0002] Most of the general timers can only set a time to control the opening or closing of electrical appliances, sound and light reminder devices, and some control objects need periodic intermittent work, such as: exhaust fans in the kitchen, regular ventilation in wards or pharmacies , disinfection equipment in operating rooms, fountains in parks, intermittent irrigation of lawns, neon sign advertisements, regular water supply by water pumps or regular heating of electric water heaters, etc., they need to turn on the power at regular intervals, and also need to turn off the power at regular intervals, and the timer with a single timing function Controlling these objects appears powerless. [0003] The cycle timing controller circuit of the present invention can conveniently solve the control problem of the above electric appl...
