Description

Designed for high-precision resistance measurements, the Beckhoff EL3692 is a 2-channel analog input EtherCAT Terminal capable of reading values from 100 mΩ up to 10 MΩ. It features a high-resolution 24-bit analog-to-digital converter and supports both 2-wire and 4-wire connection configurations to eliminate lead wire resistance errors. Integrating seamlessly into standard EtherCAT networks, this module provides fast, reliable, and highly stable data acquisition for industrial sensors, potentiometers, and variable resistance devices.

The EL3692 dynamically manages measuring ranges through automatic range selection or direct PLC controller configuration. Additionally, it provides built-in wiring failure detection to alert systems of open circuits, ensuring maximum operational safety and diagnostics in critical process control applications.

Features

Two high-resolution (24-bit) analog input channels dedicated to resistance measurements.
Broad measuring span from 100 mΩ up to 10 MΩ.
Flexible technology supporting both 2-wire and 4-wire connection methods.
Automatic or controller-driven range switching.
Pulse and continuous measurement modes for minimized power dissipation and self-heating.
Integrated wire failure diagnostics.
Galvanic isolation of 1500 V between the E-bus and the field potential.
Compact 12 mm terminal housing designed for efficient space utilization on DIN rails.

Applications

Precision RTD and temperature sensor monitoring.
Industrial testing benches and quality control systems.
Strain gauge and potentiometer monitoring in manufacturing environments.
Heavy duty automation systems requiring precise resistance tracking.
