Description

The BECKHOFF ELX3314-0090 is a high-precision 4-channel analog input EtherCAT Terminal designed for direct connection of thermocouples located in hazardous areas. This intrinsically safe (Ex i) terminal enables direct interface to sensors in Zone 0 or Zone 20 environments without requiring external safety barriers. It features integrated TwinSAFE SC (Single Channel) technology, allowing standard analog signals to be safely transmitted and analyzed within TwinSAFE systems.

Utilizing high-resolution 16-bit analog-to-digital conversion, the BECKHOFF ELX3314-0090 ensures accurate and repeatable temperature measurement across industrial processes. The hardware includes integrated digital filtering and characteristic curve linearization for standard thermocouple types. The terminal is designed to operate as part of an intrinsically safe EtherCAT segment, which must be powered via an ELX9560 power supply terminal.

Features

  • Four differential analog inputs optimized for temperature measurement using thermocouples.
  • Intrinsically safe (Ex i) design for direct connection to sensors in Zone 0 and Zone 20.
  • TwinSAFE SC technology for utilizing process signals in safety-directed tasks.
  • High-accuracy 16-bit resolution with integrated curve linearization.
  • Configurable digital filters and hardware-based limit value monitoring.
  • Compact 12 mm housing with individual diagnostics LEDs per channel.

Applications

  • Hazardous-area temperature sensing in chemical and petrochemical processes.
  • Industrial furnace, boiler, and thermal treatment monitoring.
  • Oil and gas refining, transport, and storage facility automation.
  • Safety-related temperature monitoring within TwinSAFE system environments.

Installation Guidelines

  1. De-energize System: Completely disconnect all power sources from the bus terminal system before installing, wiring, or removing components.
  2. DIN Rail Mounting: Securely snap the terminal onto a standard 35 mm DIN rail (EN 60715) ensuring proper fit of the double slot and key connection.
  3. Intrinsically Safe Segmentation: Install the terminal exclusively within an ELX-series segment powered by a dedicated ELX9560 power supply terminal.
  4. Cable Separation: Maintain physical separation between intrinsically safe (Ex i) field wiring and non-intrinsically safe power and signal cables.
  5. Grounding and Shielding: Connect the shielding in accordance with local hazardous area electrical regulations and ensure low-impedance grounding of the DIN rail.

Replacement and Configuration Guidelines

When replacing a BECKHOFF ELX3314-0090, record the channel terminal wiring layout before disconnection. Mount the replacement unit and configure the matching sensor type, filtering, and scaling parameters in TwinCAT using the appropriate EtherCAT Slave Information (ESI) file. Verify any TwinSAFE SC configurations to confirm proper diagnostic integration into the safety program.
