Digital monitoring relay Current monitoring, 22.5 mm from 2-500 mA AC/DC 0vershoot and undershoot 24 to 240 V AC/DC 50 to 60 Hz DC and AC ON delay and noise pulses delay 0.1 to 20 s Hysteresis 0.1 to 250 mA 1 change-over contact with or without fault buffer screw terminal Successor product for 3UG3521-1AL20, 3UG3521-1AG20 and 3UG3521-1AC48-0AA1 Current monitoring relay with digital setting SIRIUS 3UG4 for monitoring currents for overshooting and undershooting, e.g. for ensuring the functionality of electrical loads or for open-circuit monitoring.
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. In addition, they are available in various voltages, and optionally 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.
