EL3001, EL3002 | 1-, 2-channel analog input terminals -10…+10 V, single-ended, 12 bits

The EL3001 and EL3002 analog input terminals process 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 Terminals are single-ended inputs with a common, internal ground potential. The EL3001 is the single-channel version and is characterised by its fine granularity and electrical isolation. The EL3002 version combines two channels in one housing. The signal state of the EtherCAT Terminals is indicated by light emitting diodes.
