Integrated circuit for controlling time-delay by time-delay module

Abstract

The invention relates to a time delay module, in particular to an integrated circuit which controls time delay through the time delay module. The time delay module of the invention is composed of a CPU, an input normal closed switch control signal J1, an output normal open switch signal J5, an input 12V power supply J3 and a time delay control bridle wire OPTION, wherein the time delay is mainly controlled by a base plate CPU. The time delay module enters the working state after a DC12V power supply is input on a receiving terminal J3 and a normal open switch control signal is input on a receiving terminal J1, simultaneously, a normal open switch signal is input on the receiving terminal J5, a closing signal is input on the receiving terminal J1, the receiving terminal J5 outputs a closing signal after CPU time delay, and the delay time can be set according to different conditions. The time delay module is mainly used in entrance guard systems which are installed on large-scale department stores, office buildings, resident dwelling high-rise buildings and the like, and has and the effects of accurate delay time, simple time delay setting, simple circuits, easy construction, low cost and good burglarproof effect.

Description

technical field [0001] The present invention relates to a time delay module, in particular to an integrated circuit for controlling the time delay through the time delay module. Good anti-theft effect, simple operation, safe and reliable. technical background [0002] The delay circuit currently used, the conventional delay is to rely on the electronic component resistance R and capacitor C to realize the delay function. Due to the change of the delay element in the manufacturing process and the difficulty of adjusting the delay after it is manufactured, it is impossible to achieve an accurate delay time. , very inconvenient to use. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a delay module with precise delay time and easy delay setting, simple circuit, easy implementation, low cost and good anti-theft function. [0004] In order to realize the above technical solution, the delay mod...
