WM30 is a modular power analyzer for single-, two- and three-phase systems. It is made up of a maximum of four components: the main unit that displays measurements on the LCD display and manages 4 alarms, and three accessory modules, one with digital outputs, one with analogue outputs and the other for communication. The digital output module associates alarms with static or relay outputs and/or transmits pulses proportional to energy consumption. The analogue output module associates 0-20 mA or 0-10 V outputs to measured variables. The communication module allows you configure the analyzer and transmit data using a different communication protocol according to the version.
