The Beckhoff EL2002 is a 2-channel digital output EtherCAT Terminal designed to reliably switch 24 V DC loads in automation systems. Compact and efficient, it provides dependable control of actuators and devices such as solenoids, relays, indicator lamps, and small motors, making it a versatile building block for distributed I/O architectures.

Each channel of the EL2002 can switch loads up to 0.5 A, providing sufficient capacity for a wide variety of field devices. The terminal is designed for ohmic, inductive, and lamp loads, ensuring flexibility across different applications. Its short-circuit proof design provides robust protection against wiring faults or overload conditions, while integrated reverse voltage protection safeguards connected devices and the terminal itself against incorrect wiring or polarity reversal.

The EL2002 is engineered to withstand high inrush currents, with a maximum breaking energy of less than 150 mJ per channel. This ensures reliable performance even when switching lamp loads or inductive devices that draw brief surges of current during operation. These protective features extend the service life of both the terminal and the connected devices, ensuring long-term reliability in industrial environments.

Connectivity is provided via 4-wire technology, which simplifies wiring and ensures clear separation of control and load circuits. Its compact EtherCAT housing conserves DIN rail space, enabling high-density installations while maintaining straightforward accessibility for wiring and maintenance. This makes it a practical choice for control cabinets where space optimisation is a priority.

The EL2002 integrates seamlessly into Beckhoff’s EtherCAT I/O system, providing deterministic, real-time communication with the controller. Outputs can be switched quickly and precisely, synchronised with other terminals and devices across the network. This real-time responsiveness supports advanced automation strategies such as interlocks, machine coordination, or time-critical output switching.

Typical applications for the EL2002 include driving signal lamps and pilot lights, actuating pneumatic or hydraulic valves, energising relays or contactors, and controlling small motors or actuators. It is equally suitable for machine automation, process control, and building systems, wherever compact and reliable digital outputs are required. Its robust protection and wide load compatibility ensure that it can be deployed confidently in diverse operating environments.

In summary, the Beckhoff EL2002 is a reliable 2-channel digital output terminal that combines compact design with strong protection and robust switching performance. With 24 V DC operation, up to 0.5 A per channel, short-circuit and reverse voltage protection, and EtherCAT integration, it provides precise and dependable control of field devices. As part of Beckhoff’s modular I/O platform, the EL2002 offers engineers a flexible and efficient solution for modern automation systems.
