Product Description:

The Beckhoff part number EL2911 from EtherCAT Terminal functions as a reliable module that connects industrial automation systems.

The Link unit enables safe input-to-output signal transmission, which makes it supremely useful for safety applications integrated in EtherCAT systems. The device works with at least 1-wire and 2-wire signals while allowing power integration through contacts for better installation options. The EL2911 terminal operates with one output channel that allows 10 amperes of maximum output current for covering various industrial control tasks. The terminal functions through the TwinSAFE protocol that provides Safety over EtherCAT communication for reliable and secure operation in safety-critical environments. The terminal performs fault actions within or at or below its watchdog period parameter, which allows quick safety-related interventions during errors. Energy efficiency runs high during operation because the E-bus consumes 180 mA of current, while power contact current usage depends on the load. The terminal shows horizontal installation compatibility while keeping its dimensions at 24 mm x 100 mm x 68 mm for straightforward usage in tight control panel areas.

The EL2911 fulfills the requirements of EN ISO 13849-1:2015 (Cat. 4, PL e) and EN 61508:2010 (SIL 3) safety standards to serve systems demanding high-performance reliability. The IP20 protection standard of this terminal provides sufficient shielding against dust intrusion while preventing users from touching the inside electronics. The device combines a 98 g weight with polycarbonate construction to function properly in industrial processing environments. The device includes signal LEDs that enable users to monitor its operational status easily. It can be purchased at Wake Industrial with a one-year warranty.
