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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eFeatures\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eOriginal FT4232HL chip, fast communicating, stable and reliable, better compatibility\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSupports USB to 4-ch multi-functional serial port, convenient for expanding or debugging various industrial serial port devices\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSupports USB to 2-ch isolated RS485\/422 + 2-ch isolated RS485\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eUnibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eUnibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eTVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning proof \u0026amp;
