I/O Modules Troubleshooting

Check if the power supply voltage level is OK and that there is no high voltage (> 24 VAC or > 40 VDC) connected to the inputs/outputs of the XF821AU, XFL821AU, XF822AU, XFL822AU, XFR822AU, XFLR822AU, XF823AU, and XFL823AU I/O modules.

Replace the problem I/O module with another module of the same kind.

If the problem persists, this is an indication that the problem is caused by the application or incorrect wiring.

If the problem is solved, this is an indication that the I/O module was defective.

For troubleshooting purposes on all I/O modules the following features can be used:
