The EL3122 analog input terminal processes signals in the range between 4 and 20 mA. The current is digitized to a resolution of 16 bits and is transmitted, electrically isolated, to the higher-level automation device.
The EL4122 analog output terminal generates signals in the range between 4 and 20 mA. The power is supplied to the process level with a resolution of 16 bits and is electrically isolated. Ground potential for the output channels of the EtherCAT Terminal is common with the 24 V DC supply. The output stages are powered by the 24 V supply. The EL4122 combines two channels in one housing. The signal state of the EtherCAT Terminal is indicated by light emitting diodes.
The KL3122 analog input terminal handles signals in the range from 4 to 20 mA. The current is digitized to a resolution of 16 bits (the default is 15 bits), and is transmitted, in an electrically isolated form, to the higher-level automation device.
