EL4712

EL4712 is a Beckhoff terminal in the EL EtherCAT Terminals series. It provides two single-ended outputs with a common ground reference and uses a 24 V output supply. Its 16-bit resolution, including the sign bit, provides signed output values. Both channels are sampled simultaneously, keeping their output timing aligned. The terminal supports a maximum output rate of 100 ksamples/s and a maximum oversampling factor of 100, allowing multiple output values to be processed within one control cycle. Distributed-clock precision is less than 100 ns for closely synchronized operation.

The process image width is n × 2 × 16 bits plus 2 × 16 bits plus 4 bytes, accommodating oversampled output data, channel values, and associated control information. The supported load is less than 500 Ω, and interference deviation is 5%. The terminal draws 100 mA from the E-bus. It mounts on a 35 mm rail and has an IP20 protection class, providing finger protection while requiring an enclosure for exposure to water or fine contaminants. It supports a maximum relative humidity of 95%.
