GRI8-01 Current Monitoring Relay

GRI8-01 Current monitoring relay

GRI8-01 monitoring relay serves for monitoring of heating in rail-switches, heating cables, consumption of one-phase motors, indicates current flow.

Adjustable delay 0.5 – 10 s to eliminate short current peaks.
Flexible adjustment by potentiometer, choice of 6 ranges
: AC 0.05-0.5A; AC 0.1-1A; AC 0.2-2A; AC 0.5-5A; AC 0.8-8A; AC 1.6-16A
Possible to use for current scanning from the current transformer.
Universal supply AC 24 – 240 V or DC 24 V.
Relay status is indicated by LED.
1-MODULE, DIN rail mounting.
