Additional digital Inputs Digital Inputs connected to 0VDC

Additional digital inputs connected to 0VDC serve as a way to interface external devices or systems with a control or monitoring unit. These inputs typically receive signals from digital sensors or switches that provide on/off (high/low) states. The connection to 0VDC ensures a common ground reference for accurate signal interpretation.

Use Case
In an industrial control system, digital inputs connected to 0VDC are used to monitor the status of external equipment, such as machines or sensors. When a sensor is triggered, it sends a signal to the digital input, indicating a change in state (e.g., “on” or “off”). This allows the control system to take action based on the input, such as starting or stopping machinery or triggering alarms.
