Bornier BECKHOFF EL3101 Module d'entrée analogique 1 canal EtherCAT

Description

Precision measurement in high-speed industrial control systems is achievable with the EL3101 EtherCAT analog input terminal. This compact 12 mm module is engineered to process differential analog signals within the range of +/-10 V with a digitized resolution of 16 bits (including sign). Operating directly on the Beckhoff EtherCAT E-bus system, it delivers rapid conversion speeds alongside advanced Distributed Clocks (DC) synchronization, achieving precision of less than 1 us. The hardware architecture incorporates a robust 500 V electrical isolation boundary between the communication bus and the signal circuits to protect downstream control infrastructure.

The EL3101 supports custom signal processing behaviors through configurable digital filters, including FIR (Finite Impulse Response) and IIR (Infinite Impulse Response) options. Integrated software features like limit value monitoring and adjustable process image mappings allow automation engineers to tailor data representation to specific application needs, making it a reliable choice for demanding testing, power, and process manufacturing environments.

Technical Specifications

Connections and Interfaces

Installation Guidelines

• Mount vertically on standard 35 mm DIN rails conforming to EN 60715.
• Ensure the double slot and key connection is fully locked with adjacent terminals.
• Strip field wire insulation to 8-9 mm before insertion.
• Depress the spring tension clamp using a standard flathead screwdriver during terminal wiring.
• Use solid conductors, stranded wire, or wire-end ferrules ranging from 0.08 to 2.5 mm² (AWG 28-14).
• Keep ventilation pathways clear to allow convective heat dissipation in enclosed cabinets.
