EL3161 | 1-channel analog input terminal 0…10 V, single-ended, 16 bit

The EL3161 analog input terminal processes 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 the EtherCAT Terminal have the reference ground as common ground potential. The signal state of the EtherCAT Terminal is indicated by light emitting diodes.
