AJMRTC isolated TTL to RS485 converter is an industrial serial transceiver for level conversion and long-distance communication. It adopts integrated power and signal isolation design to eliminate common-mode noise and ground potential difference, which protects your main control board from damage caused by bus surge. It runs in half-duplex mode for two-way data exchange between TTL UART and RS485 differential bus. Built-in multi-protection components improve stability in noisy factory, cabinet and field monitoring environments. It is widely used for Modbus RTU sensors, inverters, PLC communication and embedded IoT serial expansion.
