Low Insulation observed on parallel DC Supply


Low insulation is observed on 24V DC supply source DB due to many parallel path circuits required on board. Due to this low insulation, the control PCB cards are damaged frequently.

The desirable Insulation value should be 1 Mega Ohm. In a DB, If any circuit is operating in low insulation, the visual/audio information of the same should be available on the source end so that user can isolate only that circuit for DI/DR
