Miniature relay on exit(release) s7-300

M digital output module is : DO 16 x AC 120v / 230 v

322-1FH00-0AA0

and my schema is :

A1 coming DO

14 Tension of networks

11 solenoid valve .

Thank you for your help.

Hello, I linked with exits(releases) 230v of s7-300, relay PLC-RSC-230UC / 21 but when I cut my exit(release) the reel of the relay remains engaged. You could help me. Thank you

 Hello leclercq,

considering that it is a semiconductor output will have a residual voltage when it is in OFF. You have measured this with a multimeter? If you try to put in place of what you have for example a 3RH will definitely work. I think you should try to decrease this residual voltage if you want to leave this type of relay.
