Abstract

The invention discloses an input and output circuit for a solid-state relay and the solid-state relay. The relay has the advantages of high load capacity, high reliability, high insulation resistance,high overload capacity, high reliability and high salt spray resistance. The control speed is high, and the driving energy requirement is low; the overall dimension is designed to be 21.8 mm*12.8 mm*10 mm. The solid-state relay provided by the invention is compact in structure, small in size and light in weight, and the weight of the solid-state relay provided by the invention is less than 8g; under the limitation of volume and weight conditions, small output resistance, low power consumption and high output power are ensured.

Description

technical field [0001] The invention relates to an input circuit, an output circuit and a solid-state relay, in particular to an input circuit and an output circuit for a solid-state relay and a solid-state relay including the input circuit and the output circuit. Background technique [0002] Solid State Relay (Solid State Relay, abbreviated as SSR), as an important branch of the relay field, its interior is a non-contact switch composed of microelectronic circuits, discrete electronic devices, and power electronic power devices. The isolation between the control terminal and the load terminal uses photoelectric coupling or pulse signal. The input terminal of the solid state relay uses a small control signal to directly drive a large current load. [0003] The working principle of the solid-state relay is: use semiconductor devices instead of traditional electrical contacts as a non-contact switching device with relay characteristics. The single-phase SSR is a four-termina...
