EL5001-0011 | SSI monitor terminal

The EL5001-0011 SSI monitor EtherCAT Terminal is used for monitoring the data exchange between SSI master and SSI encoder (slave). The encoder is powered via the existing SSI interface. The interface circuit makes the incoming data stream available to the controller as a data word in the process image. Various operating modes can be permanently set via the control register.
