Conversor InLine® USB para série RS485 com isolador, USB-A para terminal de 4 pinos

The InLine® USB to Serial RS485 Converter with isolator connects a computer's USB-A port to RS485 devices and Modbus networks via a virtual COM port. It features galvanic isolation up to 2.5 kV, surge, lightning and ESD protection, and an integrated 120 Ω terminating resistor for reliable data transmission.

Key features

• Galvanic isolation up to 2.5 kV reduces potential differences and ground loops
• Surge, lightning and ESD protection guard against electrical interference
• Automatic direction switching in half-duplex mode, no software settings required
• FTDI FT232RNL chipset supports baud rates from 300 to 512,000 bps
• Integrated 120 Ω terminating resistor reduces signal reflections
• Supports Windows XP to Windows 11, Linux, macOS and Android
• Screw terminal ensures secure wiring; two GND terminals for ground connections or cable shielding
