This USB to RS485/422 converter has an FT4232HL chip, providing fast and stable communication and USB connectivity to a 4-channel multi-functional serial port, which is ideal for expanding or debugging a variety of industrial serial port devices. Additionally, it supports USB to 2-channel isolated RS485/422 and 2-channel isolated RS485. The converter is equipped with onboard unibody power supply isolation that provides a stable isolated voltage without the need for an external power supply for the isolated terminal.
It also has an onboard unibody digital isolation to facilitate signal isolation, increasing the converters's reliability and anti-interference capabilities while maintaining low power consumption. Furthermore, it includes an onboard TVS (Transient Voltage Suppressor) that effectively protects against surge voltage and transient spike voltage, providing lightning-proof and ESD protection. This makes it an excellent choice for industrial environments requiring reliable and secure communications.
