    industrial isolated serial converter adopts WCH CH343G chip to convert USB signal into RS232, RS485 and TTL UART. Digital isolation eliminates interference between computer side and field serial equipment. It is equipped with TVS diodes for surge and electrostatic protection, which effectively safeguards the host against voltage spikes from long-distance wiring. It supports automatic RS485 transceiver switching, adjustable TTL logic level and runs on Windows, Linux, macOS and Android. Widely used for PLC debugging, MODBUS communication, industrial sensor data acquisition and long-distance serial transmission.
