This is Waveshare Industrial Isolated USB To 4-Ch RS232 Converter, Onboard Industrial Grade Original FT4232HL Chip, Fast communication, stable & reliable, better compatibility. Supports USB to 4-ch isolated RS232, convenient for expanding multiple RS232 industrial serial devices. ( RS232 Female Port )
It has onboard protection circuits such as built-in power isolation, ADI magnetical isolation, and TVS diode. Onboard unibody power supply isolation, provides stable isolated voltage. Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, anti-static
Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, improve shock proof performance. Onboard power supply screw terminal, allows 5V~36V DC wide range input
Compatible with Mac/Linux/Android/Windows 11 / 10 / 8.1 / 8 / 7, etc
