BECKHOFF ELM3602-0000 EtherCAT Terminal

Description

The BECKHOFF ELM3602-0000 is a 2-channel analog input EtherCAT Terminal designed for IEPE and accelerometer signal measurement. Built within a durable zinc die-cast metal housing, this precision terminal delivers 24-bit resolution and supports a maximum sampling rate of 50 ksps per channel simultaneously, with selectable oversampling factors up to 100. It is engineered for integration into EtherCAT industrial automation networks, providing reliable data acquisition for vibration monitoring, acoustic analysis, and high-precision sensor applications.

This measurement terminal features advanced signal processing capabilities, including TrueRMS calculation, free numeric filters, PeakHold functions, integrator and differentiator blocks, and non-linear scaling. Connection diagnostics such as broken wire and short circuit detection help ensure operational reliability, while distributed clocks provide synchronized timing across the network with an accuracy significantly below 1 microsecond.

Installation Guidelines

1. Verify that the system power supply and EtherCAT network are completely de-energized before handling hardware.
2. Inspect the ELM3602-0000 terminal for any transport damage or bent pins.
3. Mount the terminal onto a standard 35 mm DIN rail conforming to EN 60715, ensuring the locking mechanism engages securely.
4. Connect solid conductors directly via push-in technique, or use a screwdriver for fine-stranded conductors with ferrules according to the specified cross-section limits.
5. Ensure proper shielding and grounding practices are applied to all incoming sensor cables to maintain measurement accuracy.
6. Restore power and verify module status via the integrated signal LEDs and TwinCAT engineering software.
