Beckhoff’s expanded EL51xx I/O series features enhance incremental signal analysis.

Beckhoff Automation introduced its EL51xx line of EtherCAT terminals with built-in incremental signal analysis for 5V incremental encoders via RS422, TTL signals or open collector interfaces. Available in four models, the terminals acquire incremental signals with frequencies up to 5 MHz and feature many parameterization options. Each terminal offers an integrated sensor supply, which is parameterizable to 5, 12 or 24V. Additional integrated functions include rotary axis functionality, workpiece measurement and standstill monitoring. The measurement of period, frequency and speed with a resolution of 10ns is also available. In addition, the terminals implement a duty cycle measurement of the incoming signal.
