Hi,
I have a query that if one needs to interface inputs to p.l.c. input module that are coming out various sensors/transducers?Since if I have some inputs from 220V source while some are from power transistor,s.c.r. etc.Definitely there are some inputs that have current rating more than what p.l.c. can handle. Then how can we interface such inputs?

But according to my knowledge interposing relay can be used for output side i.e. to drive high current(and voltages) connected at output terminal.
