4-channel analog input -10…+10 V, differential input, 16 bit EJ3104

EJ3104 | 4-channel analog input -10…+10 V, differential input, 16 bit

The EJ3104 analog input processes signals in the range from -10…+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 EJ3104 EtherCAT plug-in module are differential inputs.
