Where am I wrong? Please advise me. Thank you Thu Attachment test.GIF (662 Downloads)

I assume it is properly set or the module would report a power problem. Do all the outputs have this same problem? What about the inputs? Do they work? By what you state, it sounds like you have it properly configured. Unplug the output connectors and measure the output directly on the pins (carefully!!!). If the outputs are changing state, there may simply be a loose connection or a bad output connector.
