Product description:
USB interface converter is a kind of industrial automation communication, which solves the problem of no communication serial port in modern PC.
Many important devices in the industrial environment still use the RS-232/RS-422/RS-485 interface interface design, so many users use USB to
RS-232/rs-422/rs-485 converters to implement PCs with Rs-232/RS-422/ data transmission between RS-485 devices enables long-distance serial communication. The communication interface end uses optical isolation technology.
The 600W lightning surge protection circuit provides 1500V isolation voltage to effectively suppress lightning and ESD protection.
Features:
Built-in photoelectric isolator and 600W surge protection power supply can provide 1500V isolation voltage, which can effectively suppress lightning and ESD, and can effectively prevent lightning strikes and
Common ground interference
The built-in processor automatically senses the channel data flow direction to automatically determine the channel status, automatically switches the enable control circuit, and easily solves the serial port data transmission and reception conversion delay problem.
Using USB interface power supply Built-in overload protection is safe and reliable, suitable for any host USB interface access
