Problems solved by technology

Due to the relatively poor working reliability of the relay, and the complicated working conditions of the peripheral working circuit it controls, the contacts of the relay are stuck due to the high current. In addition, because the coil of the relay is energized or other When the disconnection is caused by the cause, it may cause an accident under special working conditions

Abstract

The invention consists of SCM. One output end of SCM is connected with coil of relay. The one of contacts of replay is connected with peripheral working circuit. Another output end of SCM is connected with system failure discrimination circuit. The system failure discrimination circuit consists of another contact of relay and resistor R. Another contact of relay is connected in series with resistor R.

Description

Technical field: [0001] The invention relates to a relay output circuit controller. Background technique: [0002] The existing relay output circuit controller contains a single-chip microcomputer, an output end of the single-chip microcomputer is connected with a wire package of a relay, and a group of contacts of the relay controls a peripheral working circuit. Due to the relatively poor working reliability of the relay, and the complicated working conditions of the peripheral working circuit it controls, the contacts of the relay are stuck due to the high current. In addition, because the coil of the relay is energized or otherwise When the disconnection is caused by the cause, it may cause an accident under special working conditions. Invention content: [0003] The purpose of the present invention is to provide a relay output circuit controller with high working reliability. [0004] The solution of the present invention is as follows: a single-chip microcomputer is...
