What Is SCADA? Supervisory Control Without Replacing the PLC
SCADA sits above PLCs and RTUs: it acquires field data, alarms operators, and issues supervisory commands across plants and remote assets—without replacing local deterministic control.

The 140DSI35300 is a Modicon Quantum series Digital Input Module manufactured by Schneider Electric. This module is designed for use within Quantum automation systems, providing high-density input signal processing for industrial control applications. Operating at a nominal voltage of 24 VDC, the 140DSI35300 ensures reliable acquisition of digital signals in complex automation environments. Its robust construction and integration capabilities make it suitable for various B2B industrial projects requiring precise input monitoring and system stability.
