AJMRTC RS232 to RS485/422 converter converts standard RS232 signals into differential RS485 or RS422 bus signals. Equipped with mature SP3232EEN and SP485EEN chips, it delivers stable communication across a wide baud rate spectrum. The DB9 female port connects to legacy RS232 devices, while the terminal block provides A/B/GND for RS485 and TA/TB/RA/RB/GND for RS422. Built-in protection circuits defend against static, surge and wiring faults in noisy factory environments. LED indicators show power, transmit and receive status. It works with PLC, sensors, meters and Modbus RTU equipment, ideal for industrial data acquisition and serial communication upgrades.
