Waveshare USB TO RS232 / RS485 / TTL (UART) Industrial Isolated Converter with Original FT232RL Inside Aluminium Alloy Enclosure Power/ADI Magnetical Isolation,TVS Diode

• USB TO RS232, USB TO RS485, USB TO TTL (UART), adopt original FT232RL, fast communicating, stable and reliable, better compatibility
• Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
• Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
• Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance
