The device measures electrical motor variables (voltage, current, harmonic distortion, power, energy and earth leakage current), monitoring overloads through the thermal model, controlling them and measuring other variables, such as motor and bearing temperature. It also includes a data logger function for storing trends of the electrical variables, alarms and fast data logging for storing start-up profiles. Through the communication features, it is possible to transmit all monitored variables to a supervision control system for data collection and process control. Profibus and Modbus TCP/IP protocols are available to insert the device into a majority of applications. The operator interface is freely programmable and can show instantaneous values and alarm messages. Windows-based configuration and monitoring software simplifies plant design through graphic block configuration and connection, where the blocks are all the variables that can be used, as inputs, outputs, ANSI function, electrical and temperature variables, logical functions, timers and counters.
