EL3002 | BECKHOFF | EtherCAT Terminal Analog Input Module

Description

The EL3002 is a 2-channel analog input terminal manufactured by Beckhoff, designed for high-precision voltage measurement within EtherCAT automation systems. It processes signals in the ±10 V range with 12-bit resolution, providing reliable data for industrial monitoring and control. The module utilizes a single-ended input technology and features configurable filtering options, including FIR and IIR filters, to ensure signal integrity.

Features

• 2-channel analog input (±10 V)
• 12-bit resolution (16-bit internal representation)
• Configurable input filter limit frequency (1 kHz)
• Integrated limit value monitoring and overload status indication
• Electrical isolation of 500 V between E-bus and field potential
• Compact housing with signal LEDs for diagnostic feedback

Installation Guidelines

• DIN Rail Mounting: Secure the EL3002 onto a 35 mm DIN rail (EN 60715). Use the integrated double slot and key connection for reliable side-by-side assembly.
• Wiring: The terminal accepts solid (0.08–2.5 mm²) and flexible (0.14–1.5 mm²) conductors. Use a screwdriver for spring-loaded terminal actuation. Strip wires to a length of 8–9 mm.
• Environmental: The unit is IP20 rated. Ensure installation in a clean, temperature-controlled environment within the specified -25 to +60 degC range.
• Hazardous Areas: Complies with ATEX (II 3 G Ex nA IIC T4 Gc). Ensure all local safety regulations are followed when integrating into potentially explosive atmospheres.
