Monitoring voltage relay HRN-56

Relay monitors phase sequence and failure (e.g. control of correct motor winding etc.).

DESCRIPTION

  • Supply is done from monitored voltage.
  • Supply from all phases which means that relay is functional also in case of one phase faillure.
  • Fixed time delay T1 (500ms) and adjustable time delay T2 (0-10s) to eliminate short voltage drops and peak.
  • Faulty state is indicated by LED and by opening of output relay contact.
  • 7 types according to supply.

TECHNICAL PARAMETERS

  • Monitored power voltage: 

HRN-56/120: 3 x 120 V 
HRN-56/208: 3 x 208 V
HRN-56/240: 3 x 240 V
HRN-56/400: 3 x 400 V
HRN-56/480: 3 x 480 V
HRN-56/575: 3 x 575 V

  • Umin: 70 – 95% of monitored voltage.
  • Output contact: 1x changeover 8 A/250 V AC1 (AgNi, 2500 VA).
  • 1-MODULE, DIN rail mounting (HRN-56/480 a HRN-56/575 in 3-MODULE design).
