Introduction
The EP3632 EtherCAT Box is a two-channel oversampling interface for up to two IEPE sensors with two-wire connection. The current of the integrated constant current source can be set separately to 2 mA, 4 mA or 8 mA 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 channel and second. Distributed clocks allow the measured values to be related to other parts of the plant. Except for filtering no preprocessing of the vibration amplitude values takes place in the EP3632. This is handled by the retrieving controller. The interface can be adapted to the application-specific requirements by means of adjustable filters and supply currents.
The TwinCAT 3 Condition Monitoring library offers extensive algorithms for evaluating the signals in the controller, so that the performance and flexibility advantages of the PC platform can be fully exploited.
