Product Description

Description

The BECKHOFF EL3204 is a high-precision 4-channel analog input EtherCAT Terminal designed for direct connection of resistance temperature detectors (RTDs). This terminal operates in 2-wire technology, allowing for reliable and space-efficient temperature measurement across diverse industrial automation environments.

Equipped with a highly configurable microprocessor, the BECKHOFF EL3204 linearizes signals across the entire operating temperature range. It supports a broad array of sensor types, including popular Pt and Ni series standards, as well as direct resistance/potentiometer measurements. Internal digitizing is executed with a high 16-bit resolution to ensure precise process data transmission to the controller.

This compact 12 mm terminal is powered directly via the E-bus, eliminating the need for external field-side supply connections. With integrated diagnostics, a configurable digital filter, and limit value monitoring, the terminal provides a robust and highly integrated temperature measurement interface within any EtherCAT network architecture.

Features

  • Supports four independent temperature channels using 2-wire connection technology.
  • Compatible with Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni1000, and KTY sensor curves.
  • Offers a generic resistance measurement function for potentiometers and sensor elements up to 4 kOhm.
  • High-resolution 16-bit analog-to-digital conversion yielding 0.1 degC per digit.
  • Configurable conversion times from 2 ms to 800 ms (default setting at approximately 85 ms).
  • Complete electrical isolation of 500 V between the E-bus and the measurement channel electronics.
  • Integrated digital filtering and software-configurable limit-value monitoring.

Applications

  • Industrial thermal regulation and climate control systems.
  • Motor, bearing, and winding temperature monitoring in drive systems.
  • Process instrumentation requiring multi-channel resistance temperature measurements.
  • Thermal management within modular EtherCAT control platforms.

Installation Guidelines

  1. De-energize the System: Ensure the power supply is completely disconnected from the TwinCAT system and adjacent terminal blocks before commencing installation.
  2. Mount the Terminal: Align the terminal with the 35 mm DIN rail (EN 60715) and press until the locking mechanism clicks securely into place. Maintain appropriate structural slot-and-key side-by-side alignment.
  3. Verify Power Requirements: Verify that your EtherCAT Coupler or preceding terminal can supply the required typ. 190 mA of E-bus current.
  4. Conduct Wire Connection: Strip the wires to 8–9 mm. Activate the spring-clamp using a screwdriver, insert the conductor (solid or flexible), and release to clamp.
  5. Run Diagnostic Check: Apply system power and check the integrated status LEDs for channel state and communication health within TwinCAT.
