Simple counting type bidirectional timing controller

Abstract

The invention relates to a simple counting type bidirectional timing controller which is composed of time relays, intermediate relays, a combined switch and a control button. Time-delay power-on within a range of 0.01s-99.99h can be realized and time-delay power-off control within the range of 0.01s-99.99h can also be realized via the design of the time relays and the intermediate relays and combined switch and connecting lines. Time-delay power-on within the range of 0.01s-99.99h can be realized and time-delay power-off control within the range of 0.01s-99.99h can also be realized so that production field automatic control equipment, lighting electrical appliance time-delay control, maintenance place warning lamp control, automatic cycle equipment control and forward and backward rotation equipment control and the like are facilitated. The simple counting type bidirectional timing controller can also be popularized and applied to the aspects of warehouse and household antitheft control.

Description

technical field [0001] The invention belongs to the technical field of timing controllers, and relates to a simple counting type bidirectional timing controller. Background technique [0002] At present, most of the known timing controllers are software timing, or use the internal timing mechanism of the CPU, use software programming, or utilize a microprocessor to execute a delay program segment to realize. There are various finished products on the market, with various shapes and complex internal structures, and users need to buy them before they can be used. This is inconvenient for the on-site maintenance personnel of enterprises. In an enterprise, if such a timer needs to be used, a plan must be made first, and after being approved by all levels of departments, it will be handed over to the ordering department for procurement, and it will be obtained after a few months, which is very time-consuming and laborious. Therefore, can the required timers be formed by using th...
