Beckhoff EL3124-0090 EtherCAT Terminal

The Beckhoff EL3124-0090 is a high-precision 4-channel analog input EtherCAT Terminal designed for differential current measurements in the 4–20 mA range. Featuring 16-bit resolution and electrical isolation, it transmits analog signals safely and reliably to higher-level controllers. Integrated TwinSAFE SC (Single Channel) functionality allows standard signals to be safely evaluated in accordance with safety requirements, enabling innovative safety architectures without dedicated safety wiring. Recognizable by its distinctive yellow front stripe, the EL3124-0090 is ideal for process control systems where safety, precision, and integration are paramount.
