Where to Find ABB AC800M Manual - Control.com

It must be hot there today...lol.

109.5°F at the moment.

But, really, this yahoo would be irritating if I were in the Arctic.

i believe that is quite close - (i still haven't realized at this point WTH the S800 is)

You are correct, you did not explain your problem very well. From the sparse valid information you provided I could search for the users manual of a ABB DCS IT input card but that should be your job. I have no idea at all what type of proximity switch you have. You might have a switch and controller electronics package that is simply not going to work with an interface circuit. Lots of very bright people have ordered the wrong parts. I do not understand why you think that you have only two nodes to work with. You have at least three; signal, +24V, 24V RTN.

You just need to use 24 VDC power for inductive NPN two wire proximity which u have used for ABB card

u r using -ve as common use the same common for NPN two wire inductive proximity blue cable and connect proximity black cable to ABB digital input card

at the time of inductive proximity enrgise state it will became NC from NO stat and u will get input. +ve at ABB digital input card

Your cards and sensors are simply not compatible, most European IO cards are expecting positive voltage input as 1, they are common ve-, npn type sensors are trying to connect IO cards to ve- when activated. So you need to change your sensors to pnp type or pure dry contact type, otherwise you will need to add a converting relay for each such kind of inputs, wire the coil to ve+ and ouptput of proximity switch, then you have freedom to use contacts of that relay. Change IO cards to negative input cards is another option, if you have a big bunch of sensors already installed. Profibus IO cards like Beckhoff offered that kind of solutions, they have both positive input cards or negative input cards and they can be hooked to European CPUs most of the time.

npn sensors are compatible to Japan or American IO cards, like Mitsubishi, AB.

Don't really understand your question...
