Digital monitoring relay Voltage monitoring, 22.5 mm from 10 to 600V AC/DC above and below AC/DC 24 to 240 V DC and AC 50 to 60 Hz Interference peak delay 0.1 to 20 s Hysteresis 0.1 to 300 V 1 changeover contact with or without fault memory Screw connection successor product for 3UG3532-1AL20, 3UG3532-1AG20 SIRIUS 3UG4 digitally adjustable voltage monitoring relay for monitoring voltages that are too high or too low, for example to protect a system from damage, to protect against deep discharge of the battery or to switch a system on at a defined voltage.Worldwide use through international certificates. The relay can be set variably to over-, under-shoot 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 diagnostics by displaying ACTUAL value and status messages. All versions with removable connection terminals.In addition to screw connection technology, the devices are also continuously available with spring-type terminals for a fast, maintenance-free and vibration-proof connection. The devices differ in self-supplied and externally supplied devices, either in wide voltage or with IO-Link.The comprehensive accessories, such as device identification plates, insertion lugs and cover caps, are uniform for all relays.SIRIUS relay - a program for all cases.This text is machine translated.
