Beckhoff Automation released the EL51xx EtherCAT Terminals, which features built-in incremental signal analysis functionality. As incremental encoders have become increasingly more important due to their compactness, the EL51xx series meets the need for analysis of 5V incremental encoders wiith RS422 and TTL signals.

Per a company press release, The EL51xx series now includes:

·       EL5102: 2-channel incremental encoder interface, 5 V (RS422, TTL, open collector)

·       EL5112: 2-channel incremental encoder interface, 5 V (2 x AB or 1 x ABC RS422, TTL, open collector)

·       EL5122: 2-channel incremental encoder interface, 5 V single-ended (TTL, open collector)

·       EL5131: 1-channel incremental encoder interface, 5 V with two parameterizable 24 V DC outputs

The new series, which includes four terminals, comes equipped with eXtreme Fast Control (XFC) technology, enabling analysis of incremental signals in the controller.

Signals are acquired with frequencies up to 5MHz and come with parameterization options and integrated functions that enable optimum adaption to control tasks.

Further, the terminals offer integrated sensor supplies that is parameterizable to 5, 12 or 24 V. Users are able to connect encoders with differential RS422, 5V TTL, or open collector interfaces.

Additionally, it’s based on internal pull-up resistors, eliminating the need for external wiring.
