What is PCB Power Relay
PCB power relay is a miniaturized electronic control device, in which the circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances. The relay has control system (also known as input circuit) and controlled system (also known as output circuit). It is usually used in automatic control circuit. In fact, it is an “automatic switch” that uses small current to control large current. Therefore, it plays the role of automatic regulation, safety protection and conversion circuit in the circuit.

Use Attention of PCB Power relay
- When using AC inductive load, high transient voltage and surge current are applied to the output end, which may lead to the conduction or damage of solid-state relay. Generally, voltage control devices with specific clamping voltage, such as two-wire zener diode or varistor (MOV), need to be connected to the output end. Varistor is recommended to be 1.6-1.9 times of rated voltage;
- For DC inductive loads, such as solenoids, electromagnets and solenoid valves, freewheeling circuits must be used to suppress the back EMF generated during shutdown. Generally, a simpler method is to connect a secondary tube in reverse parallel with the load, but this circuit will affect the release time of inductive loads, such as electromagnetic relays, contacts, electromagnets and solenoid valves, A better line is that a diode and a voltage stabilizing diode are connected in reverse series, or a diode is connected in series with a resistor and then connected in reverse parallel with the load.
- When controlling a small current load close to the minimum load current, a virtual load resistance must be connected in parallel on the load to reduce the leakage current at the output end and produce a higher residual voltage on the load.
- When the circuit board welding installation relay is welded and installed, the welding temperature must be controlled below 260 ℃ and the welding time must be controlled below 5S.
- In order to avoid the temperature rise of solid-state relay exceeding the allowable value, the heat dissipation effect and installation position shall be considered in the design and application. When two or more solid-state relays are installed side by side, appropriate spacing shall be reserved.
Application area of PCB power relay
It is widely used in petrochemical instruments and equipment, food machinery, packaging machinery, textile machinery, CNC machine tools, plastic machinery, fitness equipment, entertainment facilities and other automatic control fields. It can control small motors, incandescent lamps, indicator lights, low-power power supplies, intelligent instruments and meters and various solenoid valves. It can also be used as the driving level of high-power electromagnetic contactors. It is especially suitable for corrosive, humid, dustproof, explosion-proof and other harsh environments, as well as frequent switching occasions.
