Description

The BECKHOFF EL2911 is an EtherCAT Terminal equipped with integrated TwinSAFE logic, functioning as a link unit between safe input and output signals within an industrial automation network. This safety-related I/O component combines secure logic processing and signal connection capabilities directly on the EtherCAT terminal bus, allowing safety functions to be implemented locally and decentralized across the machine topology.

Designed for integration into standard Beckhoff terminal segments, the EL2911 communicates via the Safety over EtherCAT (FSoE) protocol, enabling safety-critical data to be transmitted alongside standard process data over the same physical Ethernet cable without requiring dedicated safety wiring networks.

Features

Integrated TwinSAFE logic for decentralized safety applications
Safety over EtherCAT (FSoE) communication protocol support
Combines safe input and output handling within a compact terminal housing
Direct connection to the EtherCAT E-bus for system communication
Power contacts supporting up to 10 A current load for field-side supply
Status indication via onboard signal LEDs

Applications

Decentralized machine safety architectures requiring local logic processing
Safety-instrumented conveyor systems and material handling equipment
Industrial machinery requiring Cat. 4, PL e and SIL 3 compliance
Modular manufacturing cells utilizing Safety over EtherCAT networks

Installation Guidelines

Verify the exact model number (EL2911) against system engineering documentation prior to installation.
Ensure all power supplies and field voltage sources are completely switched off and locked out before handling the terminal.
Inspect the terminal housing, contacts, and mechanical locking mechanisms for any transit damage.
Mount the terminal onto the 35 mm DIN rail by snapping it into place alongside existing EtherCAT terminals using the double slot and key connection.
Connect solid, stranded, or ferruled conductors to the spring-actuation connection points using a suitable screwdriver, ensuring proper stripping lengths (8 to 9 mm).
Confirm proper seating of power contacts and E-bus connectors between adjacent terminal blocks.
Restore power only after verifying all safety wiring, network connections, and TwinSAFE configuration parameters within the TwinCAT engineering environment.
