Abstract

The invention discloses a solid state relay and application thereof, and the relay comprises an input part which comprises a Hall switch P1, a diode D3, a diode D4, a triode Q1, a resistor R2, a resistor R1 and a resistor R4; an output part which comprises a field effect transistor Q4, a field effect transistor Q5, a field effect transistor Q6 and a field effect transistor Q7, wherein the field effect transistor Q4 and the field effect transistor Q5 are used as a group of outputs, and the field effect transistor Q6 and the field effect transistor Q7 are used as a group of outputs; and an isolation part which is used for isolating the input part and the output part and comprises an isolator U1 and an isolator U2. The solid-state relay senses an external magnetic field signal through the Hall switch, and the input part, the output part and the isolation part realize a conversion function under the action of the magnetic field signal; the isolation part is used for isolating input and output, and it is guaranteed that electrical parameters are not interfered by an external magnetic field; a two-way output mode is adopted, positive and negative output ends can be regardless, a user can randomly stipulate that current enters from one section and exits from the other end, and flexible conversion is achieved.

Description

technical field [0001] The invention belongs to the field of electronic appliances, and in particular relates to a solid state relay and its application. Background technique [0002] The solid state relay is mainly used in the control system for monitoring the magnetic field. The switching of the solid state relay is controlled by an external magnetic field. The solid state relay introduces a Hall switch element to meet the magnetic switching function of the solid state relay. [0003] When the traditional solid state relay monitors the magnetic field in the magnetic field monitoring system, the magnetic induction element, the external control circuit and the solid state relay are combined to form a monitoring system, which results in a large size and low reliability of the monitoring system. Contents of the invention [0004] The purpose of the present invention here is to provide a solid state relay that can switch the internal on and off of the solid state relay throug...
