Description:
This USB PC adapter is an optoelectronic isolation adapter designed for industrial use. It provides surge and lightning protection for both the USB and RS485 interfaces. The 7972-0CB20-OXAO is an optical isolator for industrial design with USB and RS485 ports. It features surge and lightning protection circuitry for Siemens S7-300/400 and S7-200 series PLCs. It is particularly suitable for sensitive industrial field communication connections, providing a variety of protective measures to ensure safe system operation.
Photoelectric isolator:
This device is also known as a photocoupler or short-circuit optocoupler. Optical couplers use light as a medium for transmitting electrical signals. It provides excellent isolation of input and output signals. The main advantages of optocouplers are: unidirectional signal transmission, electrical isolation at the input and output ends, no interference from the output signal at the input end, strong interference suppression, and stable operation.
