EL5002 | SSI encoder interfaces

The EL5002 2-channel SSI interface EtherCAT Terminal allows the direct connection of two SSI encoders. 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.
