The Klockner Moeller EM4-201-DX2 Expansion IO Module adds dedicated digital I/O capacity to an EM4-201-DX2 PLC system, enabling you to extend sensing and control without replacing the main controller. Designed for 24 V DC logic and compatible with Moeller EM4 devices, this expansion module connects through the Suconet bus to synchronize I/O with the central processor. Use cases include expanding inputs for safety interlocks, sensors, or actuator control in compact automation cabinets, conveyors, and machine automation, providing additional channels while keeping the primary PLC footprint unchanged.
