USB TO RS232/485/422/TTL isolated USB to RS232/485/422/TTL converter

Description

An isolated USB - RS232/RS485/Rs422/TTL converter for industrial applications that provides easy communication between the USB interface and RS232, RS485, RS422 and TTL standards. The converter is based on the popular FT232RLN chip and a number of built-in protection circuits, such as power isolation, ADI magnetic isolation and TVS diode, which ensure high reliability of the device. A built-in self-voltage fuse and protection diodes ensure stable current and voltage outputs and provide overvoltage protection. The module also has a built-in voltage level converter for operation in 3.3 V and 5 V TTL systems. The converter is characterised by fast communication, stability, reliability and safety. It is therefore the ideal choice for industrial control devices and applications with high communication requirements. Full documentation including the necessary drivers is available on the product wiki page.
