Product Q&A

• Q: Can the input threshold be adjusted for different battery voltages?
  • A: Yes, the pick-up voltage levels are configurable to ensure reliable operation across common substation DC voltages.
• Q: Does this module support time-stamping?
  • A: All inputs on this BIM are scanned at high frequency to provide millisecond-accurate event recording within the IED.
• Q: Is the 1MRK000508-BDR04 hot-swappable?
  • A: While the hardware is robust, it is recommended to de-energize the IED or follow specific safety protocols before removing internal modules.
