EL1258 EtherCAT Terminal
The EL1258 digital input terminal acquires the fast binary 24 V control signals from the process level and transmits them, in an electrically isolated form, to the controller. Each EtherCAT Terminal has eight channels that indicate their signal state via light emitting diodes.
