EL3161, EL3162 | 1-, 2-channel analog input terminals 0…10 V, single-ended, 16 bits

The EL3161 and EL3162 analog input terminals process signals in the range between 0 and 10 V. The voltage is digitised to a resolution of 16 bits, and is transmitted, electrically isolated, to the higher-level automation device. The input channels of an EtherCAT Terminal have the reference ground as common ground potential. The EL3161 is the single-channel version. The EL3162 combines two channels in one housing. The signal state of the EtherCAT Terminals is indicated by light emitting diodes.
