This is a rephrasing of an earlier thread - which should be deleted - sorry, I'm new new to the forum concept - don't know how to delete an earlier thread!
Please advise if it is acceptable to use the CPU power supply unit PS 307 5A 24VDC/0VDC supply outlets to power a SM322 32xDO 24VDC/0.5A (6ES7 322-BL00-0AA0) module.
I have wired the DO module front connector correctly and connected it to the PS 307 5A in order to observe the LED indication of output status.
There were no lamps or other loads connected to the outputs.
Now, with the module re-established in its industrial setting and connected up to indicator lamps I find there is insufficient power to drive more than 2 lamps whereas last week, before taking the module out, ALL lamps could be simultaneously driven - during Lamp Test for example
Could the module have been damaged by operating it without output load in the form of the indicator lamps?
When I connect certain lamps other LEDs on module glow or pulse dimly even though output is "0" - a possible earth fault?
