EL3632 | EtherCAT Terminal, 2-channel analog input, IEPE/accelerometer, 16 bit, 50 ksps
Distributed Clocks: the integrated time management system in EtherCAT
SPS IPC Drives 2018:
Measurement technology with Bus Terminals: Functional overview and parameterisation
Measurement technology easily configured: Analog EtherCAT input terminals.
Measurement technology simply integrated: With the analog EtherCAT Terminals.
Accelerometers with IEPE interface can be directly connected to the EL3632 EtherCAT Terminal. The measuring signals are analyzed on the PC via the TwinCAT library. This enables all benefits of the PC platform, such as performance and flexibility, to be fully utilized. Alternatively, custom software can be used for the analysis. The terminal can be adapted to individual requirements through configurable filters and supply currents.
A galvanically isolated measurement configuration can be achieved using the EL9560. Through interfacing via EtherCAT and support of the distributed clocks function, the measurement results – and any detected defects – can be precisely allocated to an axis position.
