USB/RS232/RS485/TTL Converter, Isolated USB/RS232/RS485/TTL multi-channel converter

Multibus USB/RS232/RS485/TTL converter with integrated power supply isolation, digital isolation and protection circuits.

Peculiarities:
- Convert USB/RS232/TTL to RS232/RS485/TTL;
- Original FT232RL chip, fast communication, stable and reliable;
- Built-in overvoltage and overcurrent protection circuits;
- Power supply isolation, ensure stable isolated voltage;
- Built-in magnetic isolation, ensuring signal isolation, high reliability, strong anti-interference, low power consumption;
- Built-in TVS (transient voltage suppressor), effectively suppresses overvoltage and transient peak voltage in the circuit;
- Built-in self-healing fuse and protection diodes ensure stable current/voltage outputs;
- Built-in TTL 3.3V/5V voltage converter, group B terminal TTL level setting by switch;
- Aluminum alloy body.
