This application provides all the necessary circuitry and software to interface a DC motor to a PCS Controller or a PLC on a Chip IC or Module. The motor direction and speed is controlled using two Pulse Width Modulation channels. The circuitry is designed to be optically isolated for noise immunity and all the components required are listed.
