Monitoring voltage relay HRN-42

Monitoring DC / AC 1-phase in 3 ranges. 

DESCRIPTION

  • Monitoring voltage with 2 independent levels (overvoltage/undervoltage).
  • MEMORY function – manual reset key on frontal panel.
  • Function of second relay (independent/parallel).
  • Adjustable delay for short peaks.
  • Setting the Umax level (in% range) and the monitored Umin levels (in% of the set upper limit– function WINDOW)
  • Galvanically isolated supply voltage. (Instead of monitoring relays HRN-3)

TECHNICAL PARAMETERS

  • Power voltage AC 230 V, AC 400 V or AC/DC 24 V
  • Monitored ranges

1. range: 10 – 50 V (Input resistance 212 kΩ, max. permanent voltage 100 V)
2. range: 32 – 160 V (Input resistance 676 kΩ, max. permanent voltage 300 V)
3. range: 100 – 500 V (Input resistance 2,12 MΩ, max. permanent voltage 600 V)

  • Output contact: 2x changeover 16 A/250 V AC1 (AgNi, 4 000 VA) for all monitored levels.
  • 3- module, DIN rail mounting.
