BECKHOFF EL3008 8-Channel Analog Input Terminal
Product Code:EL3008
Description
The EL3008 analog input terminal 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. The power contacts are connected through. The reference ground for all inputs is the 0 V power contact. The signal state of the EtherCAT Terminal is indicated by light emitting diodes.
