EL3201 | BECKHOFF | EtherCAT Terminal RTD Input Module

Description

The EL3201 is a high-precision 1-channel analog input terminal by Beckhoff designed for industrial temperature measurement. It supports a wide array of RTD sensors, including Pt and Ni types, as well as general resistance measurements. The module offers flexible connection technologies, supporting 2-, 3-, and 4-wire configurations to ensure accurate readings by compensating for lead resistance. With a resolution of 0.1 degC per digit and a robust digital filter, the EL3201 provides reliable thermal data for complex EtherCAT control systems.

Features

• 1-channel RTD input with support for Pt and Ni sensors
• Flexible 2-, 3-, and 4-wire connection technologies
• High resolution of 0.1 degC per digit
• Integrated digital filtering and limit value monitoring
• Electrical isolation of 500 V between E-bus and signal voltage
• Compact, DIN rail-mountable housing with status LEDs

Technical Specifications

Installation Guidelines

• Wiring: The terminal uses spring-loaded connections. For high-precision applications, a 4-wire connection is recommended to eliminate the impact of lead resistance.
• Mounting: Snap onto a 35 mm DIN rail (EN 60715). Use the double slot and key connection for stable mechanical integration.
• Environmental: Ensure the module is kept within its IP20 environmental rating; avoid exposure to condensation or extreme dust/moisture.
• Safety: For installation in hazardous areas, ensure adherence to the ATEX rating (II 3 G Ex nA IIC T4 Gc).
