Digital monitoring relay for current monitoring, 22.5 mm for IO-Link AC/DC 0.05...10.0 A. Overcurrent and undercurrent converter scaling factor, hysteresis from 0.01 to 5.0 A, start-up delay time, and trigger delay time. Equipped with a changeover contact and screw connection. Digitally adjustable current monitoring relay SIRIUS 3UG4 for monitoring currents for over- and under-thresholds, for example, to ensure the functionality of electrical consumers or for wire break monitoring. Suitable for global use due to international certifications. The relay can be variably set for over-, under-threshold, or window monitoring. Delay times and RESET behavior are freely parameterizable. Reduced space requirement in the control cabinet thanks to a narrow width. Reliable diagnostics through the display of actual values and status messages. All versions come with removable connection terminals. In addition to screw connection technology, the devices are also available with spring-loaded connections for quick, maintenance-free, and vibration-resistant connections. They are also available in various voltages, optionally with IO-Link. The comprehensive accessories, such as device identification labels, insertion tabs, and cover caps, are uniform for all relays. SIRIUS relays - a program for all cases.
