Industrial USB to 4-Ch Serial Converter, Original FT4232HL Chip, Supports USB to RS232/485/422/TTL, Multiple Devices Applicable, Multi-OS Compatible

Adopts original FT4232HL chip, fast communicating, stable and reliable, better compatibility. 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. 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; 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; Fully automatic transceiver circuit with no delay, ensures fast and stable communication between the USB port and different interfaces, without interfering with each other. Onboard TTL serial 3.3V /5V voltage translator, config the TTL level via switch; 9 LEDs for indicating the power and transceiver status. High quality USB-B connectors, smoothly plug/pull. Industrial grade metal case, supports wall-mount installation, solid and beautiful, easy to install
