    Does Schneider Electric offer a direct replacement for the Berger Lahr D900 series of drive cards?

    No, there is no drop-in replacement available to replace the Berger Lahr D900.xx drive cards.
    This includes all versions of D900.  
    D900.00, D900.50, D900.51, D900.53, D900.61, D900.62, D900.63.... and all others that are not listed but are part of the D900 family.


    Customers must upgrade to Lexium SD326DU25S2
    They must also replace the existing stepping motor with a BRS3xxW version
    Motors used with D900 drive cards are not compatible with SD326 due to a lower voltage rating of the motor windings.   Example: VRDM3910/50 LNA   
    The "N" character in the motor type code designates a motor winding rated for 130v.
    Motors used with SD326 have a winding rated for 325v

    It should be noted that all frame sizes of motors used with D900 drive cards are available in the Lexium BRS motor family so replacement of the motor will not require any mechanical adaptation.

    Contact Schneider Electric Technical Support for assistance with selecting suitable BRS motor when upgrading from D900 drive cards to Lexium SD326.
