Waveshare Industrial USB 4-Ch Serial Converter, Original USB

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
