EL4022 | 2-channel analog output terminal 4…20 mA, 12 bit

The EL4022 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 12 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 EL4022 combines two channels in one housing. The signal state of the EtherCAT Terminal is indicated by light emitting diodes.
