Braking functions. 'Caution and stumbling' functionality by using two sensor circuits with various response temperatures in order to end up being able to react before shutdown (at the.g.
Switch in additional air conditioning, reduce load). Multimotor protection with a solitary device, y.g. For conveyor lines where various motors require to end up being switched off concurrently. Benefits at a glimpse. One device covers all electric motor powers. General make use of through dual terminal labeling for supervising relays and overload security equipment.

SIRIUS 3UG4 and 3RL2 monitoring relays facilitate the supervising of different electric and mechanised parameters in the feeder and dependable system security against harm. The relays can be installed in stand-alone set up (3UH4); on the other hand, the 3RL2 current monitoring exchange can end up being directly incorporated in the feeder by easy plug-on mounting on SIRIUS 3RT2 contactors. SIRIUS supervising relays not really only function freely parameterizable threshold values and a lot more adjustment options, but also provide definitive diagnostics and are usually even able to correct an wrong phase sequence autonomously. Several versions are also accessible with IO-Link user interface for link to the control. Find out more about IO-Link: The positive result: Targeted prevention of production errors - lasting increase of availability and productivity.
There are usually supervising relays available for the following applications:. For security against overheating Thermistor motor defense relays supply decisive advantages in situations in which current-dependent defense making use of either a outlet breaker or an overload relay is not really the ideal solution. In specific situations, overheating can occur without getting detected by the cold weather picture in the routine breaker or overload relay, for instance in the case of large starting, procedure with regularity converters, strong braking procedures or limited ventilation. The SIRIUS 3RN2 thermistor electric motor protection relays shield the engine reliably against overheating as they keep track of the turning temp of motors directly. The heat of strong, liquefied and gaseous press signifies the almost all frequently measured parameter in industrial applications.

Not least because of this reality perform SIRIUS temp supervising relays assist as the ideal gadgets for program defense. They monitor process temperature ranges just as reliably as the temp inside control cupboards or engines - if needed actually with upward to three sensors at the same period. Analog and electronic versions are usually accessible to suit various needs. Numerous versions are furthermore available with IO-Link interface for connection to the control.
