This is an industrial USB to RS485 converter with original FT232RL inside. Built-in gas discharge tube, self-recovery fuse, ESD and TVS protection circuit. It is small and exquisite. Simple operation with automatic transmitting, receiving and conversion. It features fast communications speed, stability, safety and reliability. It is perfect for a variety of industrial control equipment or applications with high communications requirements.

Features:

- USB to RS485 communications

- Original FT232RL for high-speed communications, with stability and reliability, better compatibility

- On-board TVS (Transient Voltage Suppressor) effectively suppresses surge voltage and transient spike voltage in the circuit, lightning-proof & anti-static

- On-board self-recovery fuse and protection diodes ensure stable output of current and voltage, provides over-current/over-voltage protections, improve shock resistance ability

- 3 LED indicators for checking power supply and signal transceiving status
