Renesas Electronics Entry-Level DC PLC Module Solution

Renesas Electronics Entry-Level DC PLC Module Solution provides a simple way to prolong the reach of a single 1:1 serial RS232 communication line. A GreenPAK™ communication translator takes the serial input/output and interposes a high-frequency signal on the DC power line, which is in turn decoded by a second similar circuit. Simple power line communication transfers UART data from/to a command station to the remote station over the power connection, and a simple UART connection between stations allows the addition of proprietary protocols. A DC/DC regulator allows running communications over a DC power line carrying 36V_DC maximum while also powering the connected unit with the required low voltage for the MCU.
