Cards not powering from 24v input


  • I have 24vdc connected on the 10-24vdc input with no power.  However, when connecting the pi via usbc input it powers the pi and the sequent cards.   Should I be using the 5v input with 5vdc xformer? 



  • Just confirmed 5vdc input on the 5v header works fine, but I do prefer to power this with 24v. 


  • Hi,

    This card can be used with either a 5V or a 24V power supply. Both power rails with his fuse. I assume the 24V fuse is blown, but you can check that with a multimeter.

     


  • @alexburcea  thanks.  I spoke with sequent this morning, possibly you.  This will all be powered by the ups card when it arrives, so no need to troubleshoot.

    *Disregard this   It's a software issue in Relay Equipment Manager.  4rel4in command line is reporting fine.

    I think the workaround only worked for powering the card.  I'm having a different issue now.  

    I set inputs to jumper 2-3 and connected 3 10k thermistors.  Checking from +5v to the first header pin I see 5v.  Second pin sees around 3-4v, but I'm not getting any data from the card.  

    All relays are operating normally. 


  • Could you give me more info? What do you mean you're not getting any data from the card?

    Have you connected a thermistor to get the temperature or a dry contact to read his state?
