Description

The EL3002 analog input terminal processes signals in the range between -10 and +10 V. The voltage is digitised to a resolution of 12 bits, and is transmitted, electrically isolated, to the higher-level automation device. The input channels of the EtherCAT Terminal are single-ended inputs with a common, internal ground potential. The signal state of the EtherCAT Terminals is indicated by light emitting diodes.
