Harmony Control. This current monitoring relay monitors a conductor for exceedance or undershoot of the set limit value in the range 2-500 mA. Two relay changeover switches are available for reporting, which can be loaded up to 5 A. The mode of operation, the limit value, the switching hysteresis and a drop-out delay are adjustable. The settings are made using control elements on the front, which can be protected against changes under a transparent cover. The width is 35 mm and it is mounted on the top hat rail. The wide-voltage power supply 24-240 VAC/DC (50-60 Hz) enables universal use. The cable connection is made using screw terminals.
