Hi there i have a question regarding NPN conection at Alen Bradly RsLogix500 1756ID32 Digital card input.
How do i connect from my Inditop Unit for Alfalaval valve in to my plc for NPN conection?
 
I believe is 1756-IB32 not ID32 and 1756 is a controllogix things and should be RSlogix 5000, and are you talking about the open and close feedback valve?.. please elaborate
 
I've never heard of a 1756-ID32. The 1756-IB32 has sinking inputs for use with PNP (sourcing) devices. The 1756-IV32 has sourcing inputs for use with NPN (sinking) devices.
