8-channel analog input -10…+10 V, 6 x differential input, 2 x single-ended, 16 bit EJ3108

EJ3108 | 8-channel analog input -10…+10 V, 6 x differential input, 2 x single-ended, 16 bit

The EJ3108 analog input processes signals in the range between -10 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 eight input channels of the EJ3108 include six differential inputs and two single-ended inputs. The signal state of the EJ3108 is indicated by light emitting diodes.
