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 Chip: Onboard original FT232RNL chip, Fast communication, stable & reliable, better compatibility.
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
Multi system Support: Supports Mac, Linux, Android, Windows 11 / 10 / 8.1 / 8 / 7, etc.
