Beckhoff EL3681 analog input terminal

The EL3681 is a single-channel digital multimeter terminal from the Beckhoff EtherCAT Terminal series, designed for direct measurement of voltage, current, resistance, and other electrical quantities within the EtherCAT I/O system. It integrates a full digital multimeter function into a standard 12 mm EtherCAT terminal, enabling automated electrical measurement, test, and calibration tasks directly from the controller. It is commonly used in test benches, automated production testing, and diagnostic applications.
