Usb To 4ch Rs232485

Features

• Adopts original FT4232HL chip, fast communicating, stable and reliable, better compatibility.
• Supports USB to RS232, USB to RS485.
• Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal.
• Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, and low power consumption.
• Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightningproof and ESD protection.
• Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, and improve shockproof performance.
• Built-in 120ohm resistance on RS485 output interfaces, and users can enable it through a DIP switch, easy and flexible.
• 9 LEDs for indicating the power, debugging status, and transceiver status.
• Industrial grade metal case, supports wall-mount and rail-mount installation, solid and beautiful, easy to install.
