EPP4174-0002 | 4-channel analog output ±10 V or 0/4…20 mA, parameterisable, 16 bit

The EPP4174 EtherCAT P 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.

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 P Box modules.
