The ECAT-2000 is equipped with EtherCAT protocol and installed by daisy chain connection which allowing flexibility in devices installation and reduces infrastructure and operation costs. All the modules can be deployed in the network topologies such as star, line or ring. The isolation input and output is designed to protect the ECAT-2000 against the harmful interference and environment. The ECAT-2016N is equipped with 1-channel analog input terminal that allows direct connection to a resistor bridge. Users can obtain the input status via the process data. Passed and verified by the conformance test tool, therefore eligible EtherCAT Master or configurator can manipulate it simply and implement your various applications easily.
