S7/200 24vdc ? on the 110v model?

Hello everyone,

I want to buy a S7/200, the ones I have are 24vdc, I am looking for a 110v and know that the part numbers tell you the voltage (ie xxxx xxx-x(A/B)xxx-xxxx) so A=24 vcd and B=110v

So now to my question if I buy a 110vac do they have built in transformers? some others do GE, AB, Mit but some others don't AD (model dependent) so I was wondering do the S7/200 110v model have and 24vdc output?

Or does anyone have a link to the manual or wiring guide

Many thanks
Mark

Hello Mark;

Here is a link to the S7-200 system manual; if it does not provide all the required answers, come back to the forum:
http://support.automation.siemens.com/WW/view/en/1109582

If you look in the appendices, in the CPU technical specifications, you will see that the models wirh part no. 6ES721x-xBD23-0XB0 have AC power, DC inputs and relay outputs. So you can probably use the outputs as required in your projects.

Hope this helps,

VERY MUCH...

Do you know how many Google pages and Siemens pages that I looked at, looking for that and I even search here (bad idea)

Thanks,
