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?
Just any relay should work, I like the Allen Bradley 700HK series myself, they are din mounted,SPDT relays that do not take up much space in the panel.
You just need to go to ab.com and get the part number for 24vdc coil from the online catalog.
