Siemens Sirius 3UG4 Monitoring relay

Digital monitoring relay speed monitoring from 0.1 to 2200 rpm 1 changeover contact with or without fault buffer spring connection system. Speed monitoring relay with digital setting SIRIUS 3UG4 for speed monitoring on overshoot and undershoot, e.g. in the event of slipping or cracks in a belt drive, and also suitable for slow-rotating motors. Worldwide use due to a wide voltage supply range and international certificates. Fast commissioning possible thanks to menu-driven parameterization and display of current values for threshold determination. The units have a permanent display of actual value and error type. 2- or 3-wire sensors and sensors with mechanical switching output or semiconductor output can be connected. Auxiliary voltage to sensor is integrated. Equipment replacement possible without rewiring due to removable terminals. Reliable system diagnostics thanks to unequivocal error messages on the display and connectable error memory. In addition to screw terminals, all devices are also available with spring terminals for quick, maintenance-free, and vibration-proof connection. They are available as an option with IO-Link. The comprehensive range of accessories, such as device nameplates, push-in shoes, and cover caps, is standardized for all relays. SIRIUS relays - a series for every application.
