4-channel analog input -10…+10 V, single-ended, 12 bit EJ3004

EJ3004 | 4-channel analog input -10…+10 V, single-ended, 12 bit

The EJ3004 analog input processes 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. In the EtherCAT plug-in module, the four single ended inputs are 2-wire versions and have a common, internal ground potential. The signal state of the EJ3004 is indicated by light emitting diodes.
