Waveshare Convertitore Industriale USB a 4-Ch Seriale

Caratteristiche principali

• 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
