Digital monitoring relay current monitoring, 22.5 mm from 0.05-10 A AC/DC overshoot and undershoot Supply voltage: AC/DC 24 V DC and AC 50 to 60 Hz without galvanic isolation from the measuring circuit Start-up and interference peak delay 0.1 to 20 s Hysteresis 0.01 to 5 A 1 changeover contact with or without error memory Spring-loaded technology Digitally adjustable current monitoring relay SIRIUS 3UG4 for monitoring currents for overshoot and undershoot, e.g. to ensure the functionality of electrical consumers or for wire break monitoring. Worldwide use thanks to international certificates. 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 diagnostics 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 also available in various voltages, optionally with IO-Link. The comprehensive range of accessories, such as device identification plates, push-in tabs and cover caps, is standard for all relays. SIRIUS relays - one program for all cases.
