Introduction
The EP4174 EtherCAT Box has four analog outputs which can be individually parameterised, 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.
The four outputs have a common ground potential, which is galvanically isolated from the ground potentials of the supply voltages. The analog actuators are supplied from the load voltage (freely selectable up to 30 VDC). The applied load voltage is available for actuator supply of further EtherCAT Box modules.
