Industrial USB to RS485/422 Converter FT232RL

The USB to RS485 / RS422 is an industrial-grade, isolated USB to RS485/422 converter. It uses the original FT232RNL, an industrial rail design, built-in protection circuits such as power isolation, ADI magnetic coupling isolation, and TVS. The USB to RS485/422 is easy to use and can automatically transmit and receive without delay. It is characterized by high communication speed, stability, reliability, and safety, and can be used for various industrial control devices or applications with high communication requirements. 

Features: 

• Integrated original FT232RL and SP485EEN enable fast communication, stable and reliable, compatibility. 
• Integrated power isolation provides stable isolated voltage and no additional power supply is needed for the isolated terminal. 
• The converter has TVS fuses to suppress surges and voltage spikes. 
• Integrated self-recovery fuse and protection diodes ensure stable current/voltage outputs, provide protection against overcurrent/overvoltage, and improve impact resistance 
• It has a built-in 15KV ESD isolation protection and 600W lightning and surge protection. 
• Integrated 120R termination resistor on the RS485/RS422 ports 
• The converter has 3LEDs as status indicators. 
• The converter features an industrial ABS housing design for rail mounting, which is small, easy to install, and cost-effective.
