EL1144 EtherCAT Terminal
The EL1144 digital input terminal acquires the binary 12 V control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The EtherCAT Terminal has four channels that indicate their signal state via light emitting diodes. The 12 V supply voltage can be generated with the EL9512 power supply terminal, and fed into the power contacts.
