EL4014, EL4018, EL4114 | 4-, 8-channel analog output terminals 0…20 mA, 12/16 bits
The EL4014, EL4018 and EL4114 analog output terminals generate analog output signals in the range between 0 and 20 mA. The power is supplied to the process level with a resolution of 12 bits (EL4014/EL4018) or 16 bits (EL4114) and is electrically isolated. Ground potential for the output channels of an EtherCAT Terminal is common with the 24 V DC supply. The output stages are powered by the 24 V supply. The EL4014 and EL4114 versions have four channels. The EL4018 combines eight channels in one housing. The EtherCAT Terminals indicate their signal state by means of light emitting diodes.
