EL4011, EL4012, EL4112 | 1-, 2-channel analog output terminals 0…20 mA, 12/16 bits

The EL4011, EL4012 and EL4112 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 (EL4011/EL4012) or 16 bits (EL4112) and is electrically isolated. Ground potential for the output channels of an EtherCAT Terminal is common with the 0 V DC supply. The output stages are powered by the 24 V supply. The EL4011 is a single-channel version. The EL4012 and the EL4112 combine two channels in one housing. The EtherCAT Terminals indicate their signal state by means of light emitting diodes.
