[?]: Relay output issues

Post by reymond_craig » Mon May 18, 2009 1:49 pm

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

Hello!

Here are the manuals:

For S7-300

For S7-400

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