    Need help. How to wire Fault Relay contact ?

    See attached screenshot. R2C is common & R2A is normally open contact.

    When VFD drive gets faulted or not running, I would like to get input to Micrologix PLC.

    Do I need to provide +24Vdc to R2C ? Let me know

     

    Thanks !

    Hello RAJ,

    If your 24VDC input card has a common of 0vdc or neg(-) of the power supply you are using then you need 24VDC+ on either contact. The other contact wire should go back to the input terminal you want to use.

    Hope the pic came out OK. See Attachment
