BECKHOFF EL3048 EtherCAT 8 Channel Analog Current Input Terminal
The Beckhoff EL3048 is a high-density EtherCAT analog input terminal designed for industrial current signal acquisition. It supports eight single-ended input channels for measuring signals in the range of 0 to 20 mA. The module digitizes the input signals with 12-bit resolution and transmits them electrically isolated to the higher-level automation controller.
The EL3048 integrates eight channels into a compact 12 mm-wide housing, making it ideal for applications requiring multiple analog inputs while minimizing cabinet space. Advanced FIR/IIR filtering and limit monitoring functions improve measurement stability and reliability.
