NGRM

LINETRAXX® NGRM700

  • Volledig configureerbaar
  • Ontworpen voor eenvoudige retrofit
  • Meertalige gebruikersinterface
  • Kan werken in systemen op 5000 m boven zeeniveau zonder derating

De NGRM700 is een geavanceerd apparaat waarmee de NGR-bewaking alle nodige informatie over de aarding van het systeem kan bieden. De NGRM700 bewaakt de weerstandswaarde van de nulgeleiderweerstand (NGR) naar aarde en de foutstroom die door de NGR vloeit in HRG-systemen (High Resistance Grounded).

Het relais kan worden aangesloten op het visualisatiesystemen of rechtstreeks op het communicatienetwerk.

Met de NGRM700 kan de gebruiker aan de lokale vereisten voldoen.

Accessory for FP200-NGRM: Transparent front cover 144x72 (for IP65)*B98060005

*When using the "transparent front cover 144x72 (IP 65)" the cutout in the switchboard cabinet must be extended in height from 66 mm to 68 mm (+0.7/-0 mm).

The degree of protection IP65 applies only to the user interface FP200-NGRM when using the front cover. The degree of protection for the complete device is still IP30.
