In the lifecycle management of ABB DCS 400/500B/600 series DC speed control systems, the continuity of spare parts supply is the top priority to ensure stable operation of the production line. When the built-in I/O on the standard SDCS-CON-2 control board of the system cannot meet complex on-site requirements, engineers usually introduce the SDCS-IOB-3 (I/O CONNECT. BD) expansion board. As a key interface for analog and pulse encoder signals, it is widely used in speed feedback, temperature monitoring, and upper computer analog control of transmission systems
