EL3004, EL3008 | 4-, 8-channel analog input terminals -10…+10 V, single-ended, 12 bit

The EL3004 and EL3008 analog input terminals process 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 EL3004 EtherCAT Terminal, the four single ended inputs are 2-wire versions and have a common, internal ground potential. The EL3008 version combines eight channels in one housing. The power contacts are connected through. The reference ground for all inputs is the 0 V power contact. The signal state of the EtherCAT Terminals is indicated by light emitting diodes.
