To answer the need for incremental encoders due to their compactness, Beckhoff created the comprehensive EL51xx EtherCAT Terminal series for analysis of 5 V incremental encoders via RS422 and TTL signals. Thanks to their extension by four highly compact and high-performance I/Os, analysis of incremental signals in the controller can now be implemented in an even more space-saving and cost-effective manner.

Incremental signals with high frequencies up to 5 MHz

The four new EtherCAT Terminals feature numerous parameterization options and integrated functions that enable optimum adaptation to control tasks. Each EtherCAT Terminal offers an integrated sensor supply, parameterizable to 5, 12 or 24 V. Encoders with differential RS422, 5 V TTL or open collector interface can be connected. Based on internal pull-up resistors, no external wiring is required for open collector analysis. Additional 24 V digital inputs are used to save, lock and set the counter value.
