Miniature time relay

Abstract

The invention discloses a miniature time relay, and the time relay comprises a power supply loop which enables an input AC voltage to be converted into a needed DC voltage through voltage reduction rectification, and supplies power to other loops; the display loop is used for displaying the working state of the miniature time relay to a user in real time through an indicator lamp; the timing loop is composed of a special programmable timing integrated circuit and peripheral electronic components, provides a time delay function for the miniature time relay, and provides a level trigger signal for the output of the output loop; the output loop is used for reading the time delay signal in the timing loop, and controlling an internal intermediate relay to act if a delay ending signal is read; compared with the prior art, the reliability and the accuracy are greatly improved, the labor cost and the material cost of manufacturers are greatly saved, and the production efficiency and the user experience are improved.

Description

technical field [0001] The invention belongs to the field of electronic equipment, and in particular relates to a miniature time relay. Background technique [0002] The time relay is a novel time relay produced by ASIC and professional manufacturing technology. It has the characteristics of small size, light weight, compact structure, high delay precision, wide delay range, good reliability and long life. It is suitable for delay control in various automatic control places that require high precision and high reliability. [0003] At present, the internal circuits of the time relays produced by major manufacturers are complicated, the debugging steps of the delay time are complicated, the production process is cumbersome, and the production efficiency is low. The volume is too large to adapt to the control environment with micro volume and high integration requirements. [0004] At present, there is no product in China that can meet the user's requirements for time relays...
