EtherCAT Terminals Analog Input

Interface Modules

The Beckhoff EL3104 is a compact EtherCAT Terminal designed for high-precision analog voltage measurement in industrial automation systems. This terminal features four differential analog input channels capable of processing signals in the range of -10 to +10 V DC. The voltage signals are digitized with 16-bit resolution including sign, providing accurate measurement data that is transmitted electrically isolated to higher-level automation devices via the EtherCAT fieldbus protocol. The differential input design minimizes noise interference, making it suitable for demanding measurement applications. The terminal supports distributed clocks for synchronized data acquisition across EtherCAT networks and includes configurable FIR/IIR filters and limit value monitoring. With its compact 12 mm housing width, DIN-rail mounting capability, and IP20 protection rating, the EL3104 integrates seamlessly into modular PC-based control systems for sensor monitoring, process value acquisition, and machine diagnostics.
