Universal voltage or current detecting and
monitoring relay
71.41.8.230.1021 - Voltage monitoring
71.51.8.230.1021 - Current monitoring
• Zero voltage memory according to
EN 60204-7-5
• Programmable for DC or AC detection level:
- range detecting: upper and lower value
- upper set point minus hysteresis range
(5...50)% for switch on
- lower set point plus hysteresis range
(5...50)% for switch on
• Fault memory
• Electrical isolation between measuring
and supply circuits
• Immune to supply interruptions of < 200 ms
• Wide detecting range:
- voltage: DC (15...700)V, AC (15...480)V
• 35 mm rail (EN 60715) mounting
Features
• Programmable universal voltage monitoring
relay
• Programmable universal current monitoring relay
• Usable with current transformer 50/5, 100/5,
150/5, 250/5, 300/5, 400/5 or 600/5
