The photorelay is a semiconductor relay used in combination of AC and DC, and is a device in which a light emitting device and a light receiving device are integrated. The input and output sides are electrically insulated, but signals can be transmitted via optical signals.
The photorelay has the advantages of no mechanical contacts, long life, low operating current, high isolation voltage, high-speed switching, and low leakage current.
The photorelay is a semiconductor relay used in combination with AC / DC, and refers to a device in which a light emitting device and a light receiving device are integrated. The input and output sides are electrically insulated, but signals can be transmitted via optical signals.
Whether the photorelay has mechanical contacts, long life, low operating current, high isolation voltage, and high-speed switching. Low leakage current, both AC and DC. Widely used in measuring instruments, communication equipment, office automation.
Mainly used in measurement equipment, communication equipment, security equipment, medical equipment, etc.
There are many types of relays. In actual use, users can generally choose according to the classification and selection of manufacturers. This classification is as follows: (1) Signal relay: suitable for occasions requiring signal switching, such as communication, security and fire protection, AV equipment, etc.
(2) Power relay: widely used in home appliances, industrial control, power supply, security, office automation, etc.
(3) Electric power relay: It is suitable for metering, relay protection, industrial automation and other fields.
(4) Industrial relay: widely used in elevators, machine tools, electric power, metallurgy, environmental protection, cement and other industries.
(5) Automotive relays: used in power, chassis, security, anti-theft, driving information and body electronic systems.
