The ECAT-2055 is built in isolated 8 digital inputs and 8 digital outputs. Users can obtain the input and output status not only via the process data but also from its LED indicators. It has passed and verified by the conformance test tool, therefore eligible EtherCAT Master or configurator can manipulate it simply and implement your various applications easily.
