AJMRTC isolated USB to RS485 converter uses FT232RNL controller to convert USB signal into standard RS485 differential serial bus. The isolation barrier separates USB side and RS485 side, effectively preventing ground potential difference damage and noise interference. Multiple protection circuits guard against static, surge, overcurrent and reverse connection. Automatic transceiver control simplifies wiring for Modbus RTU, PLC, industrial sensors, meters and automation equipment. It comes with PWR, TX, RX indicator lights to check communication status at a glance. Ideal for factory automation, data acquisition, equipment debugging and long-distance serial communication.
