EP5001-0002 | SSI encoder interface

The EP5001 EtherCAT Box is an interface for the direct connection of SSI encoders with differential inputs (RS485).The interface circuit generates a pulse for reading the encoder and makes the incoming data stream available to the controller as a data word in the process image. Various operating modes, transmission frequencies and bit widths can be permanently stored in a control register. The encoder is connected via an 8-pin M12 socket.
