PRI-51/16A is a current monitoring relay for the Imax level in 1-phase AC circuits, e.g. for monitoring heating in rail switches and heating cables.
Key features
- Current range: AC 1.6 – 16 A (AC 50-60 Hz)
- Tripping level set smoothly by potentiometer
- Adjustable delay 0.5 – 10 s to ignore short current peaks
- Supply AC 24 – 240 V and DC 24 V, galvanically separated from the measured current
- Output: 1× changeover 8 A/AC1
- 1-module DIN rail housing, 90 × 17.6 × 64 mm
