Electronics Repair Questions? Ask an Electronics Technician
Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Question, please, before I try to answer your question finally:
What do you define a 'source voltage' on an output?
- as, 'the output is from the source of a UJT or similar component internal to the controller'?
- or something else -?
Let me know please. Thanks.
So in other words the controller in this case does not have a 24 VDC power supply to the chip in general and does not use such a supply nor switch it on its outputs. Rather, it has a 24 VDC (or perhaps 'within that range' input) that it switches on its outputs. Is that the case here?
