Mini USB to RS485 / RS422 Converter FTDI CHIP with Screw Terminals and Windows 10 Support


Quick Overview

USB to RS-485 / RS-422 Converter contains an FTDI Chip with terminals photoelectric interface can convert the single ended USB signal into difference RS-422 or RS-485 signal. The converter includes Transient Voltage Suppressor technology!

Availability: In stock



GM-482422 USB to RS485 / RS422 Converter FTDI Chip with Terminals photoelectric isolation interface converter can convert the single ended USB signal into difference RS422 or RS485 signal. The built-in photoelectric isolator of the USB to RS485 / RS422 Converter can provide an isolation voltage as high as 2500Vrms. There is also a rapid transient voltage suppression protector for protection of RS422 / RS485 interface with advanced TVS (Transient Voltage Suppressor) technology

Under normal conditions the TVS tube is in a state oh high resistance. However, when both ends of the TVS tube are hit by transient high energy, the impedance at the both ends can be depressed by the TVS at very high speed. After absorbing a high current, the voltage between the two ends is depressed and kept at a pre-set value; therefore no damage is caused to the electrical components behind the transient high voltage impact.

The protector can effectively restrain lighting or ESD (Electro-Static Discharge) with a protection voltage of 600w on each line for lightning surge and transient voltage events, while transmission of RS-422 / RS-485 is maintained by capacitors between the poles.
