EL4024, EL4028, EL4124 | 4-, 8-channel analog output terminals 4…20 mA, 12/16 bits
The EL4024, EL4028 and EL4124 analog output terminals generate signals in the range between 4 and 20 mA. The power is supplied to the process level with a resolution of 12 bits (EL4024/EL4028) or 16 bits (EL4124) 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 EL4024 and the EL4124 have four channels. The EL4028 combines eight channels in one housing. The signal state of the EtherCAT Terminals is indicated by light emitting diodes.
