EL5152 | 2-channel incremental encoder interface

The EL5152 EtherCAT Terminal is an interface with 24 V inputs for the direct connection of incremental encoders. With the EL5152, two 32 bit counters with quadrature decoder can be read and set.

The EL5152 supports the synchronous reading of the encoder value, together with other input data, into the EtherCAT system via high-precision EtherCAT distributed clocks (DC).
