Description

Designed for highly accurate temperature measurement in demanding industrial automation applications, the Beckhoff EL3201-0020 is a high-precision 1-channel analog input terminal configured for Resistance Temperature Detectors (RTD). This EtherCAT terminal enables direct connection of sensors utilizing 4-wire connection technology to ensure maximum measurement accuracy by compensating for cable resistance. Each module is factory-calibrated and delivered with a corresponding calibration certificate, making it suitable for applications requiring strict compliance and traceably accurate temperature logs.

The EL3201-0020 processes signals from various RTD sensor types, including Pt and Ni variants, as well as general resistance measurements. Its integration into the EtherCAT system allows for fast, deterministic communication with the central controller, translating process data directly into a 1 x 32-bit RTD process image. Features such as integrated digital filtering and configurable limit value monitoring allow for flexible adaptation to specific process dynamics.

Features

  • Single-channel high-precision analog input for temperature measurement.
  • Supports a wide range of sensor types: Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni1000, and direct resistance measurements.
  • True 4-wire connection technology for precise lead wire compensation.
  • 16-bit analog resolution offering exceptional precision of 0.01 degC per digit.
  • Factory-calibrated with a provided calibration certificate.
  • Integrated digital filtering and software-configurable limit value monitoring.
  • Direct power supply via the E-bus communication interface.

Applications

  • Precision climate and test chamber monitoring.
  • Chemical processing and reactor temperature regulation.
  • Food production and thermal processing lines.
  • Calibration laboratories and quality assurance stations.
  • HVAC and building automation monitoring.

Installation Guidelines

  • Mounting: Mount horizontally or vertically on a standard 35 mm DIN rail conforming to EN 60715. Ensure the locking slide is securely engaged.
  • Wiring Connection: Use solid, stranded, or ferruled conductors. Insert wires via spring actuation using a standard flathead screwdriver.
  • Shielding & Noise Reduction: Utilize shielded cabling for sensor lines to prevent electromagnetic interference from power and motor cables. Connect the shield directly to the fieldbus terminal earth ground.
  • E-bus Contacts: Ensure the gold-plated E-bus contact surfaces are clean and free of dust before slotting adjacent terminals together.

Compliance and Certifications

  • CE
  • UL

What sensor types are compatible with the Beckhoff EL3201-0020?

The EL3201-0020 supports a wide range of sensors including Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni1000, and resistance measurements from 10 Ohm up to 1.25 kOhm.

Why is 4-wire connection technology used in the EL3201-0020?

4-wire connection technology is utilized to provide high-precision measurements by fully compensating for the lead resistance of the sensor cabling, preventing line resistance from introducing measurement errors.

Does the EL3201-0020 terminal come with calibration documentation?

Yes, the EL3201-0020 is a factory-calibrated analog terminal and includes an individual calibration certificate.

What is the measuring error and resolution of this terminal?

It features a resolution of 0.01 degC per digit, with a measuring error of less than +/-0.1 degC at 40 degC ambient temperature using a Pt100 sensor in a 4-wire connection.
