Features
Adopts original FT2232HL chip, fast communication, stable and reliable, better compatibility
Extending USB to 2CH RS485, allows concurrent and independent communication for each channel
Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit
Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance
Built-in 120R terminal resistor on the RS485 ports, configurable via jumper for flexible switching
