  1. Dear Panic, How are you? i hope you are doing well !.

    Please i have a problem in a machine contain  output relay card 1769- OW16 and the loads are sol. valves +24 VDC many output points are failure from the output card  of two different machines with no any problem in the loads and no short circuit as all output are protected by fuses.

    so, i think the problem in the output relay card lifetime as the outputs are turn on and off with a high frequency and no any problem in any sol. coil or any fuse.

    i suggested to change to +24 VDc output card 1769- OB16 and put Phonix contact relay on all outputs for isolating the loads from the output card.

    But i do not know if i need to add a reversed diode across the relay coil or not??  and is the phonix relay is considered an inductive load or not??

    Thank You very much

      1. this is wrong use of forum. don't send personal messages, post questions in forum

      2. you provided no info on load type. inductive only refers to characteristics but not size etc. to get specific answer, you need to ask specific question (in the fORUM)

      3. i don't know either. whatever this "phoenix relay" is, does not tell the type (CR, SSR etc.)

      NOTE: i decided to not issue any warning or banning you yet but if you send me again unsolicited or personal message instead of asking for help in forum - i will reconsider that position.

      it is simple, just be a top-gun... if anyone else is better, that is not a good sign at all... :-) 

      seriously, higher education is very different from highschool, nobody will push you to work hard - you need to do this yourselves, make sure to work on your time management! make sure to not fall behind on any course, my recommendation is to read all material few days before it is actually taught in the class. this will give you chance to ask right questions and learn more than others. this will also help reduce your workload peaks... specially when exam time comes... work out all practice problems, not only recommended ones. 

      if you are interested in automation, i strongly suggest to build circuits in your spare time. it will teach you so much more than what is delivered in the class.
