USB TO RS485 (C) — Industrial Grade Isolated Bidirectional Converter
Industrial grade isolated USB to RS485 converter with original FT232RNL chip. Supports stable communication, suitable for industrial control equipment or applications with high communication requirements.
Key Features
- Supports USB to RS485 bidirectional conversion
- Onboard original FT232RNL chip, providing high-speed, stable, and reliable communication with excellent compatibility
- Onboard isolated transceiver, integrated electrical isolation and ESD protection, greatly improving communication stability and anti-interference in industrial environments
- Onboard TVS (Transient Voltage Suppressor), effectively suppressing surge voltage and transient spike voltage in the circuit, lightningproof and anti-electrostatic
- Onboard resettable fuses and protection diodes, ensuring stable current/voltage output, providing over-current/over-voltage protection, improving shock resistance
- Onboard 3 LEDs for indicating power and transceiver status
