The IE4112 analog output module generates analog output signals in the range from 0/4 to 20?mA. The power is supplied to the process level with a resolution of 15?bits (default), and is electrically isolated. If the input is transmitted without an arithmetical sign, 16?bit resolution may also be selected. If necessary, the output scaling can be altered. Ground potential for the four output channels is common with the 24?V?DC supply. The analog actuators are powered by the load voltage. The applied load voltage (which can be any value up to 30?V?DC) is fed through to supply the actuators.
