HRN-42/UNI is a voltage monitoring relay for AC or DC voltage in three ranges, with two independently monitored levels.
Key features
- Monitored ranges AC/DC 10 – 50 V, 32 – 160 V, 100 – 500 V (one input monitored at a time)
- Upper level Umax set in % of range; lower level Umin set in % of the range (WINDOW function)
- Independent time delays for Umax and Umin, 0.1 – 10 s each
- Output: 2× changeover 16 A/AC1, one contact per level; independent or parallel operation selectable
- Supply voltage AC/DC 24 – 240 V, galvanically separated from the monitoring inputs
- DIN rail housing, 90 × 52 × 65 mm
