USB to 4-ch Serial Converter It is the Industrial USB to 4-ch Serial Converter, USB To RS232/485/422/TTL. Supports USB to 4-ch multi-functional serial port, convenient for expanding or debugging various industrial serial port devices; Supports USB to 1-ch TTL + 1-ch TTL/RS485 + 1-ch isolated RS485/422 + 1-ch isolated RS232/485.
Original Industrial Grade ChipOnboard original FT232RNL chip, Fast communication, stable & reliable, better compatibility. Multi system SupportSupports Mac, Linux, Android, Windows 11 / 10 / 8.1 / 8 / 7, etc.
Safer Isolated Design Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal. Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption.
Multiple Protection, Safe And Stable Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & ESD protection. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance.
Aluminium Alloy Enclosure Aluminium alloy enclosure with sand blasting and anodic oxidation, Solid and durable; Wall-Mount Support, More flexible for industrial installation
