Features

Electronic load relays with motor management (ELR-MM) combine fast, wear-resistant, semiconductor switches and modern measurement and evaluation electronics. The active-power input of electrical drives is calculated every 6.6 ms from three currents, voltages, and the phase angle. This enables continuous status monitoring. Freely parameterizable signaling and switching thresholds for detecting under/overloads provide functions that far exceed standard motor protection. All relevant electrical values such as apparent power, active power, reactive power, currents, voltages, and phase angles, as well as the values of the internal cycle counter and elapsed-time meter can be requested via the display. Actuators and variable-speed drives, pumps, and tools are switched using the ELR-MM load relay and at the same time monitored and protected against dirt or wear. As an option, the devices can be coupled to fieldbus systems via a defined interface for online monitoring.
