EtherCAT P: The one cable solution – One step closer to automation without control cabinets

EtherCAT P: The one cable solution – One step closer to automation without control cabinets

The EPP1809-0021 EtherCAT P Box with digital inputs acquires binary control signals from the process level and transfers them, with electrical isolation, to the controller. The signal state is displayed by LEDs; the signals are connected via screwable M8 connectors.

The sensors are supplied from the control voltage US. The load voltage UP is not used in the input module. The connected sensors are supplied via an internal, short-circuit proof driver block with a total of 0.5 A for all sensors.

Thanks to the 3.0 ms input filter the EPP1809-0021 is particularly suitable for electronic and mechanical inputs, with the benefit of additional signal debouncing.
