This is Waveshare FT232RL USB TO RS232/485/TTL Interface Converter, Industrial Isolation. An industrial USB to RS232/485/TTL isolated converter from Waveshare with the original FT232RL inside. It features embedded protection circuits such as power isolation, ADI magnetical isolation, and TVS diode, etc. What’s more, the USB TO RS232/485/TTL comes with an aluminium alloy enclosure, make it solid and durable to work.

The Waveshare FT232RL USB TO RS232/485/TTL Interface Converter, Industrial Isolation is very easy to use, fully automatic transceiving without delay. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipment and/or applications with high communication requirements.


  1. Waveshare FT232RL USB TO RS232/485/TTL Interface Converter, Industrial Isolation: USB TO RS232, USB TO RS485, USB TO TTL (UART).
  2. Adopt original FT232RL, fast communicating, stable and reliable, better compatibility.
  3. Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal.
  4. Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption.
  5. Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic.
  6. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance.
  7. A fully automatic transceiver circuit with no delay ensures the USB port communicates with different interfaces fastly and stably, without interfering with each other.
  8. Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch.
  9. Aluminium alloy enclosure with sandblasting and anodic oxidation, CNC process opening, solid and durable.
