    photoeye and relay selction

    Sorry about that. I worded the question wrong. I understand how a relay works. What I had a question about was when the DC circuit energizes the coil, what is the correct contact rating. Why did you choose 10 amps? Just to make sure the rating is a couple hundred times bigger than the...

    micrologix 1200 and photoeye help

    I have a photoelectric sensor with a DC control output (PNP) of 100ma (26.4V) max. I need to interface it to a micrologix 1200 with a 120VAC input card. What kind of relay do I need to do this?
