The Beckhoff EL2912 EtherCAT Terminal is a compact and powerful safety output module designed to deliver secure control of actuators and other field devices in functional safety applications. With two safe digital outputs, TwinSAFE technology, and full EtherCAT integration, the EL2912 combines safety and flexibility within Beckhoff’s modular I/O ecosystem.

Each of the two outputs can switch 24 V DC loads with a maximum continuous current of 2 A per channel, making the EL2912 suitable for directly driving actuators such as solenoid valves, contactors, safety relays, and motor brakes. Integrated short-circuit protection and current monitoring enhance reliability by safeguarding both the module and connected devices from overloads or wiring errors.

What sets the EL2912 apart is its support for TwinSAFE Logic functionality. Unlike simple output modules, it can execute decentralised safety functions directly within the terminal, such as emergency stop logic, enabling/disabling actuators, or safety zone control. This allows system designers to implement distributed safety architectures, reducing the reliance on central safety controllers and providing modular flexibility for machine sections or subsystems.

The terminal communicates using Safety over EtherCAT (FSoE), ensuring deterministic, fail-safe exchange of safety-related data across the EtherCAT network. This enables synchronised operation with other TwinSAFE devices and guarantees reliable communication for safety-critical tasks. The fault response time is parameterizable, tied to the watchdog timer, ensuring that any unsafe condition is detected and addressed within a predictable timeframe.

The EL2912 draws its logic supply from the E-bus, consuming approximately 200 mA, while the output power is provided via the power contacts, which are load-dependent. This separation ensures stable operation, with clear distinction between control logic and field power distribution. Diagnostic LEDs on the terminal housing provide immediate feedback on channel status, communication, and error conditions, simplifying commissioning and maintenance.

Compact and space-efficient, the EL2912 integrates seamlessly into EtherCAT I/O racks. Its design supports 1-/2-wire connection technology, allowing for flexible and simple wiring of safety devices. Its robust construction and wide applicability make it suitable for use in a broad range of safety applications, including machine safety, robotics, packaging equipment, process plants, and building automation.

In summary, the Beckhoff EL2912 EtherCAT Terminal is a versatile and secure safety output module. With two 24 V DC/2 A safe outputs, TwinSAFE logic capability, FSoE communication, and parameterizable fault response, it offers engineers a reliable and flexible tool for implementing distributed safety functions in modern automation environments.
