Troubleshooting Sinking Outputs

[mprochko 0]

Hello Everyone, Had a minor question about sinking outputs and how to do you troubleshoot them. I have been working with Sourcing outputs for the last 5 years and if you want to test if the output is energized on PLC IO Card just measure to see if you get 24 VDC. However we have a customer that wants to use a automation direct dl05 with sinking outputs. If I want to troubleshoot the outputs and make sure that just the output is active before trying to diagnose wiring issues how do you do it?

Just turn your voltmeter upside down!! The procedure is still the same, but you will see 24 volts when an output is OFF and zero volts when it is ON. OR ... Measure from the output to the +24 side of the supply instead. That will give you the readings on the meter that you are used to seeing.

Your right. Figured it was me just forgetting something. Thanks for the help.
