Beckhoff ELM3604-0000 | EtherCAT Terminal, 4-channel analog input, IEPE/accelerometer

The ELM360x EtherCAT Terminals are designed for the evaluation of IEPE

sensors (Integrated Electronics Piezo-Electric), which are mainly used for

vibration diagnostics and acoustics. The constant current feed can be set

to 0/2/4 mA. The input characteristics are also flexibly adjustable from

DC to 10 Hz in the CoE. The ELM360x basically measures voltages AC/DC

and in addition, the internal scaler function can be used if, for example,

an output in acceleration [m/s²] is desired. In voltage measurement mode

12 different measurement ranges from ±20 mV to ±10 V and 0 to 20 V

are adjustable.

Irrespective of the signal configuration, all ELM modules have the same

technological properties. The ELM360x modules for IEPE evaluation offer

a maximum sampling rate of 20.000 or 50.000 samples per second. IEPE

sensors are often connected via coaxial cables, therefore the ELM360x-0002

feature a BNC connector. The 2-pin version with push-in (ELM360x-0000)

on the other hand is ideal for industrial use where a plug is unplugged

less frequently for maintenance purposes and fast wiring is much more

important.

Available on request as variant with factory calibration certificate or ISO

17025-/DAkkS-compliant certificate including Beckhoff recalibration service.

Extensive documentation is available from Beckhoff sales, support or

This ELM3xxx series measurement terminal enables efficient implementation

of complex system-integrated data acquisition systems (DAQ) that place

high demands on measurement accuracy and time synchronization.
