Beckhoff EL3024 4-Channel Analog Input Terminal

Beckhoff EL3024 EtherCAT Terminal is a four-channel analog input module that reads current-loop sensors in the 4–20 mA range with 12-bit, differential resolution. Each of the four channels converts the loop current into a digital value for the EtherCAT network, enabling precise, channelized acquisition of process signals. The differential input layout helps suppress noise common in industrial environments, improving measurement accuracy across long cables and noisy installations. As part of Beckhoff's EL30xx family of analog input terminals, the EL3024 integrates seamlessly into Beckhoff EtherCAT I/O systems and supports per-channel diagnostics, including fault indication if a wire is broken or the measured current falls outside the expected range. Typical applications include interfacing 4–20 mA process sensors in automation and control systems—such as chemical processing, water/wastewater treatment, building automation, and manufacturing lines—where reliable current-loop measurement is required. Key specifications: 4 input channels, current input 4–20 mA, 12-bit resolution, differential inputs, EtherCAT terminal interface, and built-in channel diagnostics.
