With the EE 121-1 from the S-DIAS series energy, power and phase angle can be recorded directly at the machine. The compact DIN rail module supports the user in predictive maintenance and can also be used to monitor costs.

The voltages from the 3 input phases (L1, L2 and L3) are measured and up to 12 currents are recorded which can be assigned to any phase. The voltage, as well as current inputs have a 16-bit resolution. The measuring range of the UL/CSA verified module is 0-520 V AC and 0-2 A AC.

In addition to current and voltage sequences, the EE 121-1 can be used to measure and monitor the phase position and frequency. It enables the calculation of Ueff and Ieff for each channel, as well as the energy consumption since the first activation. The module can also detect power disruptions or a phase drop and registers the 0 crossing point for the application.

The main power synchronization is also possible with the S-DIAS module. A timestamp function is hereby provided for the zero voltage crossing points. Therefore, when using several energy recording modules, the time offset of the voltage zero crossing points of two main voltages can be determined.
