EL3022
The Beckhoff EL3022 from the EL EtherCAT Terminals series by Beckhoff is a high-precision analog input terminal featuring two differential inputs with a signal current range of 4...20 mA and a resolution of 12 bit (16 bit presentation incl. sign). It delivers rapid data conversion with a default conversion time of 0.625 ms and maintains signal integrity via an input filter limit frequency of 1 kHz and a common-mode voltage of max. 10 V. The module’s internal resistance is typically 85 Ω + diode voltage, while its surge voltage resistance of max. 35 V safeguards against spikes. Powered via the E-bus with a typical consumption of 130 mA, it operates reliably across a temperature range of -25...+60 °C and can be stored between -40...+85 °C. Ideal for demanding industrial automation tasks, the EL3022 ensures accurate, robust current measurement in challenging environments.
