Single -phase solid -state relay is a non -contact electronic switch, which has the characteristics of small input power, high sensitivity, low control power, good electromagnetic compatibility, low noise and high working frequency.You can control the optoelectronic isolation between the circuit and the load circuit, and the application is widely used, such as industrial electric furnaces, oven, pumps, and electric motors.

Single -phase solid -state relay wiring
1. If the solid-state relay purchased is a zero-zero-trigger method, then the control terminal has two control wiring, voltage+and voltage-just need to connect the voltage signal within the effective range to the correct polarity on the control end.EssenceThe output of the solid relay is connected to the fire line and a single -phase fire line, respectively.2. If the crystal tube module is purchased, the control terminal has 4 control wiring, namely G1, K1, G2, K2. At this time, an additional trigger circuit needs to be added to trigger control. Generally, the pulse transformer trigger circuit is recommended.
Single -phase solid -state relay principle
1. Single -phase solid -state relay is a non -contact switch device with a relay characteristics with a semiconductor device instead of traditional electrical connection points as a switching device. The single -phase SSR is the source device of the four ends, two of whichThe input output is isolated by light. After the input terminal is added with DC or pulse signals to a certain current value, the output can be changed from a discontinued state to a general state.2. AC solid -state relay is divided into excessive voltage (referred to as zero type) and random guide type (referred to as random type) according to the switch method.3. The two -way thyristor output type (ordinary type) and unidirectional silicon condensed (enhanced) are divided into two -way thyristor output type (ordinary type).4. The needle insertion type (natural cooling, no need to bring a radiator) and the device fixed on the metal bottom plate (cooled by the radiator) used on the printing line board (cooling).
