FT232RNL USB TO RS232/485/422/TTL Interface Converter
This industrial-grade isolated USB Converter has an onboard original FT232RNL Chip, which provides fast communication, stability, high reliability, and has multi-system support including Mac, Linux, Android and Windows 11 / 10 / 8.1 / 8 / 7. The converter also has multiple conversion support, including USB to RS232, USB to RS485, USB to RS422, USB to TTL
Featuring a safer isolated design with onboard unibody power supply isolation, a stable isolated voltage, and no extra power supply needed for the isolated terminal. With a USB-B port for the power supply, an RS232 Port, and an aluminium alloy enclosure with wall-mount support for easier installation. This device is a great choice when looking for a safe, reliable and easy-to-use converter.
Features
- Original FT232RNL chip, fast communicating, stable and reliable, better compatibility
- Multiple communication interface conversion: USB to RS232, USB to RS485, USB to RS422, USB to TTL
- Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
- Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
