Digital monitoring relay Voltage monitoring, 22.5 mm from 0.1-60 V AC/DC 0vershoot and undershoot 24 to 240 V AC/DC 50 to 60 Hz DC and AC Noise pulses delay 0.1 to 20 s Hysteresis 0.1 to 30 V 1 change-over contact with or without fault buffer screw terminal Successor product for 3UG3531-1AL20, 3UG3531-1AG20 Voltage monitoring relay with digital setting SIRIUS 3UG4 for monitoring voltages for overshooting and undershooting, e.g. for protecting a system from damage, for protecting batteries against deep discharge or for connecting systems as of a specified voltage.
Worldwide use thanks to international certificates. The relay is variably adjustable to overshoot, undershoot or window monitoring. Delay times and RESET behavior are freely parameterizable. Less space required in the control cabinet thanks to slim design. Reliable diagnostics due to display of ACTUAL value and status messages. All versions with removable terminals.
In addition to screw terminals, all the devices are also available with spring-type terminals for fast, maintenance-free and vibration-proof connection. The devices differ with regard to their power supply (internal or external), optionally with wide voltage range or with IO-Link.
The comprehensive range of accessories, such as unit labeling plates, push-in lugs and cover caps, is standardized for all relays.
SIRIUS relays - one range for every application.
