Digital monitoring relay Speed monitoring for IO-Link from 0.1...2200 rpm Overshoot and undershoot Start-up delay time Tripping delay time Hysteresis 0.1 to 99 rpm 1 changeover contact, screw connection Digitally adjustable speed monitoring relay SIRIUS 3UG4 for monitoring speeds for overshoot and undershoot, e.g. in the event of slip or a belt drive breaking, also suitable for slowly rotating motors. Worldwide use thanks to wide voltage supply and internationally validated. Fast commissioning possible thanks to menu-guided parameterization and actual value display for limit value determination. The device has a permanent display of the actual value or error type. 2- or 3-wire sensors and sensors with mechanical switching or electronic output can be connected. Auxiliary voltage for the sensor is integrated. Device can be changed without rewiring thanks to removable terminals. Reliable system diagnostics thanks to clear error messages on the display and switchable error memory. 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 optionally available with IO-Link. The comprehensive range of accessories, such as device identification plates, insertion tabs and cover caps, is standard for all relays. SIRIUS relays - a program for all cases.
