R N Mart

electrical connection that provides a path to ground (DC negative) for a load. In a sinking configuration, the load connects between the power source (+) and the switching device, which then connects to the common or ground
(-). It acts as the return path, enabling current to flow through the device to complete the circuit. Sinking logic is essential for sensors or PLCs that pull current to the ground, commonly used in NPN sensor circuits. It is the opposite of sourcing, which provides the positive voltage source.
