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

* Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning proof & ESD

* protection

* Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance

* Fully automatic transceiver circuit with no delay, ensures the USB port communicates with different interfaces fastly and stably, without interfering with each other

* Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch

* 3 LEDs for indicating the power and transceiver status

* High-quality USB-B and RS232 connectors, smoothly plug/pull

* Industrial grade metal case, supports wall-mount and rail-mount installations, solid and beautiful, easy to install
