The BECKHOFF EL3174 is a four-channel analog input terminal designed for the EtherCAT I/O system. This multi-function terminal processes signals spanning voltage and current ranges, accommodating inputs such as plus/minus 10 V and plus/minus 20 mA with a 16-bit resolution. As part of the High-Density housing series, the device integrates four independent channels into a narrow 12 mm module width, making it well-suited for space-constrained control cabinets requiring multi-channel analog data acquisition.
The terminal features parameterizable input types, supporting both differential voltage measurements and single-ended current measurements. Equipped with distributed clock support capable of sub-microsecond precision, the EL3174 allows synchronized sampling across distributed automation nodes. It communicates process data via the EtherCAT E-bus, requiring no manual addressing or physical configuration switches during setup.
