Hello guys
The title of the thread is somewhat inaccurate as I am troubleshooting the devices connected to the a PLC with transistor outputs and would like to know what would happen if I connect a +24VDC to the output terminals while the PLC is powered up and wired to devices.
The PLC is powered with 24VDC and the loads are connected just like in the attache pdf, so let's say I wanted to test the device connected to Q4 by connecting a 24DC to Q4 directly to see if the device will turn on. Would that damage the transistors in the PLC?
Thanks
Kal
