Beckhoff EL5101 Encoder Interface Module

Beckhoff EL5101 is a 1-channel EtherCAT encoder interface terminal for direct connection of incremental encoders with RS422 differential signals or TTL single-ended signals. It evaluates input frequencies up to 1 MHz (4-fold: 4 million increments/s), provides microincrement interpolation (1/256) for finer position resolution, and supports EtherCAT Distributed Clocks for synchronous acquisition plus a timestamp on the last registered incremental edge. The terminal also offers additional status (5 V DC) and gate/latch (24 V DC) inputs, and can supply the encoder with 5 V (generated from 24 V power contacts) and 24 V via the terminal connection points.
