EP5151-0002 | Incremental encoder interface with single-ended inputs

The EP5151-0002 EtherCAT Box is an interface for the direct connection of incremental encoders with 24 V DC inputs. A 32/16 bit counter with a quadrature decoder and a 32/16 bit latch for the zero pulse can be read, set or enabled. Interval measurement with a resolution of up to 100 ns is possible.

Due to the optional interpolating microincrement function, the EP5151-0002 can supply even more precise axis positions for dynamic axes. In addition, it supports the synchronous reading of the encoder value together with other input data in the EtherCAT system via high-precision EtherCAT distributed clocks (DC). The encoder is connected via an 8-pin M12 socket.
