Product Description

Description

The BECKHOFF ELM3604-0002 is a high-precision, 4-channel analog input EtherCAT Terminal specifically designed for high-speed dynamic measurement applications. This measurement module is engineered to interface directly with IEPE (Integrated Electronics Piezo-Electric) sensors, accelerometers, and voltage signals, making it an ideal choice for high-accuracy industrial vibration analysis, acoustics, and structural condition monitoring.

Constructed in a durable zinc die-cast housing, the BECKHOFF ELM3604-0002 offers superior shielding and thermal dissipation characteristics. It provides high-speed simultaneous sampling up to 20 ksps per channel at a 24-bit resolution. With integrated single-ended 2-wire BNC interfaces, the terminal guarantees secure connection and optimal signal path integrity for sensitive measurement environments.

This terminal is packed with advanced onboard DSP (Digital Signal Processing) functionalities, including a free numeric filter, TrueRMS calculations, integration/differentiation, non-linear scaling, and PeakHold. These integrated math functions enable decentralized preprocessing directly on the hardware, significantly reducing the CPU load on the central EtherCAT master controller.

Features

  • Four independent, high-precision analog input channels supporting IEPE and voltage measurements.
  • Fast simultaneous sampling rates up to 20 ksps (50 µs cycle time) per channel.
  • High-resolution 24-bit analog-to-digital conversion with integrated sign bit.
  • Shielded BNC connection technology for reliable single-ended 2-wire wiring.
  • Selectable oversampling factor from n = 1 to 100 for flexible signal processing configurations.
  • Onboard signal processing features, including TrueRMS, PeakHold, non-linear scaling, and custom numeric filters.
  • Distributed Clocks (DC) support with synchronization accuracy under 1 µs.
  • Rugged zinc die-cast metal housing with integrated status and diagnostic LEDs.

Applications

  • Industrial condition monitoring and preventative maintenance of rotating machinery.
  • High-speed vibration analysis and structural health monitoring.
  • Acoustic testing, noise measurement, and dynamic load evaluation.
  • Test bench operations requiring high-accuracy, synchronized analog signal acquisition.

Installation Guidelines

  1. Ensure that the power supply to the EtherCAT system and the E-bus segment is completely disconnected before mounting or removing modules.
  2. Inspect the BECKHOFF ELM3604-0002 for any visible physical damage before mounting.
  3. Install the module on a standard 35 mm DIN rail (conforming to EN 60715) until it is securely locked into position.
  4. Secure side-by-side positioning of adjacent terminals using the double slot and key connection mechanics.
  5. Connect standard shielded BNC cables to the input ports. Always utilize shielded cabling to preserve signal integrity for sensitive dynamic measurements.
  6. Verify the system grounding path to prevent ground loops that could distort high-precision IEPE sensor readouts.
  7. Apply E-bus power and proceed with software configuration and terminal mapping via TwinCAT System Manager.
