Embodiment Construction

[0016] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to the following embodiments, and it can be foreseen that those skilled in the art may produce various changes in implementation in combination with the prior art.

[0017] On the basis of the relay parameters of the prior art, the time relay of 0.5-10A (resistance) load type can be realized by J300 electromagnetic part plus TD module or digital circuit. The TD delay module is an integrated module with high precision and large-scale delay function, which can be used in various delay circuits, such as figure 1 , is composed of TD module (HG9127, HG9129B or HG9160) and electromagnetic relay J300 constitute the action delay relay circuit schematic diagram.

[0018] The TD module and J300 electromagnetic relay in this scheme are products that have been verified by actual use (the TD module is widely used in our factory for ...

Abstract

The invention discloses a high-reliability time relay, which comprises a time delay (TD) module and an electromagnetic relay, wherein the TD module is a thick-film time delay integrated circuit; the model number is HG9127, HG9129B or HG9160; the TD module comprises an external resistor R for adjusting time delay; and the model number of the electromagnetic relay is J300. The high-reliability time relay is a product which meets the military product condition, is large in action time delay range, high in precision, small in size, light in weight and relatively large in load and has relatively high competitiveness. Particularly, in the aspect of aviation, due to high precision, small size, light quality and relatively high load, an aircraft electrical system can be greatly simplified; the overall performance of the aircraft is improved; and the high-reliability time relay has relatively high military significance.

Description

technical field [0001] The invention relates to electronic devices of the relay type, in particular to a high-reliability time relay. Background technique [0002] The existing delay relay products have a small load of 0.05A ~ 2A (resistive); the weight is more than 100g; the delay part mostly adopts the old-fashioned RC punch and discharge circuit and the NE555 chip or frequency divider to form a delay and other technologies, so The accuracy is relatively low at 10% or more. [0003] Some of its product parameters are shown in the following table: [0004] [0005] Obviously, the parameters of the delay relay products are increased to: the load is 0.5A-5A (resistive), and some products are up to 10A (resistive); the weight is only about 50g ~ 70g; the delay accuracy is about 5% ~ 8% . That is to develop a product with a large delay range, high precision, small size, light weight and large load, which has stronger competitiveness. SUMMARY OF THE INVENTION [0006] T...
