The EP4174-0002 EtherCAT Box has four analog outputs which can be individually parameterized, so that they generate signals either in the -10…+10 V or the 0/4…20 mA range. The voltage or output current is supplied to the process level with a resolution of 15 bit (default), and is electrically isolated. The output scaling can be changed if required.

Ground potential for the four output channels is common with the 24 V DC supply. The analog actuators are supplied from the load voltage (freely selectable up to 30 V DC). The applied load voltage is available for actuator supply of further EtherCAT Box modules.
