![EPP3632-0001 | EtherCAT P Box, 2-channel analog input, IEPE/accelerometer, 16 bit, 50 ksps, M8](https://multimedia.beckhoff.com/media/epp3632-0001__web_preview.png)
The EPP3632-0001 EtherCAT P Box is a 2-channel oversampling interface for up to two IEPE sensors with 2-wire connection. The current of the integrated constant current source can be set to 2, 4 or 8 mA separately for each channel depending on the sensor and cable length. The input signal is sampled according to the oversampling principle with up to 50 ksamples per second per channel. The measured values can be correlated to other parts of the system through distributed clocks. Except for filtering, the EPP3632-0001 does not pre-process the vibration amplitude values. This is done by the retrieving controller. The interface can be adapted to application-specific requirements by means of adjustable filters and supply currents. The TwinCAT 3 Condition Monitoring library offers extensive algorithms for signal evaluation in the controller, enabling full utilization of the performance and flexibility benefits of the PC platform.
