Digital monitoring relay cos phi and current monitoring for IO-Link AC 90...690 V, 0.2...10 A Overshoot and undershoot Start-up delay time Tripping delay time Hysteresis 0.1 to 3.0 A 2 changeover contacts, spring-loaded technology Digitally adjustable cos phi monitoring relay SIRIUS 3UG4 for monitoring power factor and active current for overshoot, e.g. in the case of dirty filter systems, or for undershoot, e.g. in the case of a V-belt break or pump idling. Worldwide use thanks to wide voltage and international validation. The relay also monitors smaller single-phase motors with an idle current of less than 0.5 A. Implicit monitoring for cable breakage and phase failure possible. The measuring principle cos phi or active current can be selected. Less space required in the control cabinet thanks to a narrow width. Reliable diagnosis through display of ACTUAL value and status messages. All versions with removable connection terminals.In addition to screw connection technology, the devices are also available with spring-loaded connections for a quick, maintenance-free and vibration-proof connection. They are optionally available with IO-Link.The comprehensive range of accessories, such as device identification plates, push-in tabs and cover caps, is standardized for all relays.SIRIUS relays - a program for all occasions.
