8-channel analog input terminal 0…20 mA, single-ended, 12 bit EJ3048

EJ3048 | 8-channel analog input terminal 0…20 mA, single-ended, 12 bit

The EJ3048 analog input processes signals in the range between 0 and 20 mA. The current is digitised to a resolution of 12 bits, and is transmitted, electrically isolated, to the higher-level automation device. The EJ3048 EtherCAT plug-in module combines eight channels in one housing. The signal state of the EJ3048 is indicated by light emitting diodes.
