product description:
USB interface converter is designed for industrial automation communications, solving the problem of modern PC without communication serial port, however Many important devices in the current industrial environment still use the RS-232/RS-422/RS-485 interface interface design. Many users use USB to RS-232/RS-422/RS-485 converters to implement PC and RS-232/RS-422/ Data transmission between RS-485 devices can realize long-distance serial communication. The communication interface uses optical isolation technology. 600W lightning surge protection circuit, providing 1000V isolation voltage can effectively inhibit lightning and ESD protection.
Features:
*Built-in photoelectric isolator and 600W surge protection
Can provide 2500V isolation voltage, can effectively suppress lightning and ESD, and can effectively prevent lightning and
Common ground interference
*Built-in processor automatically senses the direction of the channel data flow
Automatically determine the channel status, automatically switch the enable control circuit, and easily solve the serial data transmission and receiving conversion delay problem
*USB interface power supply
Built-in overload protection is safe and reliable, suitable for any host USB interface access
