Beckhoff EL3702 original analog input terminal

The EL3702 is a two-channel analog input terminal from the Beckhoff EtherCAT Terminal series, designed for high-speed acquisition of ±10 V signals using oversampling. It samples the input signals at a much higher rate than the EtherCAT bus cycle and transmits multiple sampled values per bus cycle to the controller, enabling precise capture of fast transient signals and high-frequency waveforms. It is commonly used for vibration analysis, transient recording, and high-dynamic measurement tasks.
