Product Name: BECKHOFF EL3044 4-Channel Analog Input Terminal Product Brand: BECKHOFF Product Code: EL3044 Product Artikel: BECKHOFF EL3044 4-Channel Analog Input Terminal
The EL3044 analog input terminal processes signals in the range between 0 and 20 mA. The current is digitised to a resolution of 12 bits and is transmitted (electrically isolated) to the higher-level automation device. The EL3044 EtherCAT Terminal features 2-wire conductors for the four single-ended inputs with a common internal ground potential. The power contacts are connected through. The signal state of the EtherCAT Terminal is indicated by light emitting diodes.
