My Experience With Sink And Source In Plc

As an automation engineer, I have worked with various programmable logic controllers (PLCs) over the years. One of the most common questions that I get asked is the difference between sink and source in PLCs.

When I first started working with PLCs, I found it confusing to understand the difference between sink and source. However, as I gained more experience, I realized that it was a crucial concept to understand to ensure the proper functioning of the system.

Difference Between Sink And Source In PLC

What Is A Sink?

In a PLC system, a sink is a device that consumes current from the output. In other words, it is a device that is connected to the negative side of the power supply. When the PLC sends a signal to the output module, the current flows from the positive side of the power supply, through the output module, and into the sink device.

What Is A Source?

A source, on the other hand, is a device that provides current to the output. In other words, it is a device that is connected to the positive side of the power supply. When the PLC sends a signal to the output module, the current flows from the source device, through the output module, and into the load.

My Personal Review And Suggestion On “Difference Between Sink And Source In PLC”

Overall, understanding the difference between sink and source in PLCs is crucial for the proper functioning of the system. While it may seem confusing at first, with experience and practice, it becomes easier to understand. I suggest that anyone working with PLCs takes the time to understand this concept and follows the appropriate safety precautions to ensure the safety of the system and the people working with it.

Question & Answer and FAQs

Q: Can I connect a DC motor to a sink output?

A: No, a DC motor requires a source output as it needs a positive voltage to operate.

Q: What is the difference between a sinking input and a sinking output?

A: A sinking input is a device that switches to ground when activated, while a sinking output is a device that provides a ground connection when activated.

Q: How do I know if a device is a sink or a source?

A: Consult the manufacturer’s documentation for the device or use a multimeter to determine the polarity of the device.
