Voltage monitoring relay HRN-42 series

2 NO/NCACAC/DC

Monitoring voltage relay HRN-42Monitoring 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 ranges1. 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.
