Introduction
The EPP1819-0005 EtherCAT P Box with digital inputs acquires binary control signals from the process level and transfers them electrically isolated to the controller. The signal state is indicated by means of LEDs. The signal connection is made via screwable 4-pin M8 connectors. This means that sensors with antivalent channels (NC/NO, change-over) can be connected directly using a 4-pin cable.
The sensors are supplied from the control voltage US. The load voltage UP is not used in the input module, but it can optionally be connected for forwarding and is fed through to the next device.
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 input filter of 10 µs, the EPP1819-0005 is preferably suitable for electronic inputs that transmit to the controller with the shortest possible delay due to the short filter time. The use of antivalent sensors also enables the sensor to be diagnosed.
