Beckhoff EL3612 2-Channel Analog Input Terminal

Beckhoff EL3612 is a 2-channel EtherCAT analog input terminal that accepts 0–20 mA current‑loop signals on each channel and converts them to 24‑bit digital values, enabling high‑resolution monitoring of current loops in automation systems. Each channel employs differential inputs to reject common‑mode noise, increasing accuracy in electrically noisy factory environments, and the device integrates seamlessly with Beckhoff's I/O system for fast cyclic data exchange. Designed for use with loop‑powered sensors and standard 4–20 mA instrumentation, the EL3612 provides two independent measurement channels with guaranteed resolution across the full 0–20 mA range, making it suitable for precision flow, pressure, and level sensors in process control. As part of Beckhoff's EL36xx EtherCAT analog input family, it occupies a fieldbus terminal slot and enables scalable expansion of current‑sense measurements within an EtherCAT network. Key specifications include two differential 0–20 mA inputs, 24‑bit resolution, and EtherCAT compatibility for synchronized data exchange with the host controller.
