Grounding Control Device EKX-4

DESCRIPTION
  • Monitored grounding during loading and unloading inflammable liquids or solids in tank trucks, silo trucks and railway wagons
  • For use in gas and dust hazardous areas of zone 1 (equipment category II 2 G) and 21 (II 2 D)
  • Prevents manipulation due to object recognition
  • Controlled derivation of the static electricity
  • Immediate interruption of the loading operation when unsafe grounding connection occurs
  • According to all currently relevant EMC and ATEX directives
  • High functional safety according to EN 61508 / SIL 2 (Hardware-Assessment)

BENEFITS OF EKX-4

  • Prevents manipulation due to object recognition (by measuring the impedance)
  • Opening of the housing during operation in gas-hazardous areas is allowed
  • Automatic diagnosis system self-monitors all safety-related functions continuously
  • Due to the cable compensation, it is also possible to connect cables up to 30 m
  • NAMUR-compatible Ex i control output
