Hi to all,

Good afternoon I just want to ask if there's a relay output card for s7-300 that has normally close contact.
And also is there anyone here that has electrical wiring diagram for relay output card module of s7 because I'm confuse right now because I saw a document that has a 16 points relay output with only 20pin front connector.
I'm thinking that a relay output that has 16pts should use a 40pin front connector.

Thank you very much

what kind of card are you using
SM 322; DO 16 x DC 24 V/ 0,5 A; (6ES7322-1BH01-0AA0)

point 1 ist 1+ 24Vdc
point 2 to 9 are the outputs 1 to 8
point 10 is 1+ ground

point 11 is 2+ 24Vdc
point 12 to 19 are the outputs 9 to 16
point 20 is 2+ ground ... 0=10805256

there you will find manuals

Here are the manuals:

For S7-300 ... n-US-1.pdf

For S7-400 ... _en-US.pdf

You can use some additional relays to have NC contacts or you can program the outputs for NO.

Best regards!
