Description

The EL5151-0021 EtherCAT Terminal is an interface with 24 V inputs for the direct connection of incremental encoders. A 32-bit counter with quadrature decoder can be connected to the interface. A 32-bit latch input for the zero pulse can be read, set or activated. In addition, a parameterisable 24 V DC output is available, which is set when a specified count value is set (compare function). The integrated workpiece measurement function enables logging of the start and end values of the counter. The measurement is triggered by the external latch input. Both values are output separately as 32-bit values.
