The Beckhoff EL2612 is a versatile 2-channel relay output EtherCAT Terminal designed for switching AC and DC loads in automation systems. With its compact design, change-over contact configuration, and wide operating range, it provides engineers with a flexible solution for integrating both signal-level and power-level switching into EtherCAT-based control architectures.

Each of the two output channels in the EL2612 uses a relay-based change-over contact, allowing it to switch between two circuits or provide reliable on/off control of a single circuit. This flexibility makes the module suitable for a wide range of tasks, including controlling actuators, switching low-power devices, or interfacing with external control systems.

The terminal is rated for up to 125 V AC and 30 V DC, supporting both alternating and direct current applications. With an ohmic switching capacity of 0.5 A per channel for AC and 2 A per channel for DC, the EL2612 can reliably manage light loads such as solenoids, relays, small motors, or signal devices. In addition, its ability to switch very small signals — down to 10 µA at 10 mV DC with intact contact coating — makes it well suited for handling sensor signals or other delicate circuits.

Relay technology provides galvanic isolation between the control system and the switched load, ensuring safety and robustness in industrial environments. This isolation protects sensitive electronics on the EtherCAT side from voltage fluctuations or disturbances in the field wiring, increasing system reliability and service life.

The EL2612 consumes approximately 150 mA from the E-bus, while integrating seamlessly into Beckhoff’s modular I/O system. It communicates status and diagnostics directly to the EtherCAT master, allowing real-time monitoring and straightforward configuration. Its compact terminal housing conserves valuable DIN rail space, enabling high-density installations and simplified cabinet layouts.

Typical applications of the EL2612 include switching auxiliary circuits, controlling signal lamps, operating small relays, or managing setpoints in process automation. Its ability to handle both low-level signals and moderate power loads makes it a practical choice for mixed applications where versatility and reliability are required. In building automation, it can control HVAC elements or low-voltage lighting, while in machine automation it provides reliable control for auxiliary devices and monitoring systems.

In summary, the Beckhoff EL2612 is a compact and flexible relay output terminal offering two change-over contacts for AC and DC loads. With voltage ratings up to 125 V AC and 30 V DC, switching capacities of 0.5 A AC and 2 A DC, and support for very low minimum loads, it delivers dependable performance across diverse applications. By combining relay isolation with EtherCAT integration, the EL2612 ensures safe, precise, and efficient switching in modern automation environments.
