How to replace a safety output card (1734-OB8S)?

[wendaiyu 0]

Hi, guys, how’s going?

 

We have an AB controller Logix5572S with safety functions. We suspect one safety output card (1734-OB8S) is defective.

 

Could you give us a help to how to replace a safety output card? We have not taken related training yet. It’s a little bit tough.

 

Thanks a lot.
