Hi all,
Great site and looking for some help.Doing my Electrician exams and PLC's are a topic on it.Heres an exam question from a past paper i cant find the answer to.Any help would be great!!
Q:
Explain the operation of a triac output module for a programmable controller and explain why the current drain must exceed its holding current.
If someone knows could they keep the answer somewhat condensed.
Many thanks,
Stephen
