What are sinking and sourcing?

Question

Accepted Answer

Sinking and Sourcing are terms used in electrical engineering to describe the flow of current in a circuit.

Sinking refers to the flow of current from the load to the ground or power supply.
Sourcing refers to the flow of current from the power supply to the load.
Sinking and sourcing are important considerations when designing circuits with microcontrollers or other digital devices.
For example, a microcontroller may use sinking or sourcing to control the flow of current to an LED.
Sinking and sourcing can also refer to the type of output used by a sensor or actuator in a control system.

Accepted Answer

Sinking
The current flows into the device from the positive terminal. The PLC provides the ground path for the current.
Sourcing
The current flows out of the device from the positive power supply. The PLC provides the positive voltage for the current
