USB To RS485 RS422 FDTI Converter

The PCM-KW-193 utilizes an authentic FTDI FT232RL chip, paired with AM26C31/32 differential transceivers, to facilitate reliable conversion from USB to RS485/RS422 industrial buses. It features a built-in automatic transmit/receive switching circuit, eliminating the need for software-based flow control. Equipped with LED indicators for transmit/receive activity and power status, it allows for real-time monitoring of operational conditions. It supports multiple operating systems (Windows, Mac, Linux) and offers plug-and-play functionality. It is widely applied in scenarios such as PLC communication, intelligent instrumentation, access control and security systems, and variable frequency drive (VFD) commissioning. The housing is constructed from interference-resistant ABS material, and the output ports are available as screw terminals or DB9 female connectors, meeting the rigorous demands of industrial environments.
