Digital monitoring relay voltage monitoring, 22.5 mm from 10 to 600V AC/DC overshoot and undershoot AC/DC 24 to 240 V DC and AC 50 to 60 Hz interference peak delay 0.1 to 20 s 1 changeover contact with or without error memory spring-loaded technology Digitally adjustable voltage monitoring relay SIRIUS 3UG4 for monitoring voltages for overshoot and undershoot, e.g. to protect a system from damage, to protect against battery deep discharge or to switch on a system from a defined voltage. Worldwide use through international validation. The relay can be variably set to overshoot, undershoot or window monitoring. Delay times and RESET behavior can be freely parameterized. 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. The devices are divided into self-supplied and externally supplied devices, optionally in a wide voltage range or with IO-Link.The comprehensive accessories, such as device identification plates, push-in tabs and cover caps, are standardized for all relays.SIRIUS relays - a program for all occasions.
