Product Description

Beckhoff produces the EL2809, an advanced industrial automation gear for dependable and durable digital output control, as part of their EL EtherCAT Terminal Series. With its space-saving design and 16 separate output channels, this little terminal module may be used for a variety of purposes. The EL2809's core capability is its nominal voltage handling capability of 24 V DC. Many industrial control systems use this particular voltage level as a standard, which makes it compatible with a range of actuators and other devices. An essential component in preserving the integrity of industrial processes is the terminal's ability to withstand voltage variations between -15% and +20%, which guarantees steady operation even in the face of potentially unstable power supply circumstances. This terminal's remarkable output current capacity is one of its best qualities. Importantly, these outputs are short-circuit resistant, and each of the 16 channels has a maximum current delivery capacity of 0.5 A.

This implies that the EL2809 can tolerate the spike in current without being harmed in the case of an unintentional short circuit, avoiding expensive repairs and downtime. Adding reverse voltage protection to every channel further strengthens this protection, protecting the terminal from improper wiring or voltage spikes. Ohmic, inductive, and light loads are just a few of the load types that the EL2809 can manage, demonstrating its flexibility. Its design, which takes into account the distinct qualities of every load type, is the reason for this wide adaptability. For example, when turned off, inductive loads like motors and solenoids produce back EMF. The internal circuitry of the EL2809 is built to control this back EMF, protecting the terminal and guaranteeing seamless functioning. The EL2809 is designed to endure the demands of industrial settings in addition to its electrical capabilities. It can operate successfully in a variety of environments because of its working temperature range of -25°C to +60°C. Additionally, even under extreme circumstances, the terminal meets EN 60068-2-6 and EN 60068-2-27 criteria for shock and vibration resistance.

In order to reduce interference with other devices and make sure that external electromagnetic noise doesn't interfere with its functioning, the EL2809 also complies with the electromagnetic compatibility standards EN 61000-6-2 and EN 61000-6-4. A cleaner and more orderly installation is made possible by the "1-wire" connection technique, which streamlines wiring and uses fewer wires. The EL2809 has an energy-efficient design with typical current usage of 140 mA on the E-bus and 35 mA (plus load) on the power contacts. With a typical turn-on time of 60 µs and a typical turn-off time of 300 µs, the terminal's quick switching speeds guarantee a prompt response to control signals, which is crucial for accurate and dynamic control of automated operations. Wake Industrial gives customers additional peace of mind and guarantees the EL2809's quality and dependability with a one-year warranty.

Frequently Asked Questions about EL2809


Q: What is the EL2809 terminal, and who manufactures it?

A: The EL2809 terminal is a 16-channel digital output EtherCAT terminal designed for industrial automation, with a nominal voltage of 24 V DC. Manufactured by Beckhoff as part of its EL EtherCAT Terminal Series, this component is used to control various types of loads, such as ohmic, inductive, and lamp loads.

Q: What types of loads can the EL2809 handle?

A: The EL2809 is versatile in its load compatibility, supporting ohmic, inductive, and lamp loads. This range is due to its carefully designed circuitry that accommodates each load type's unique electrical characteristics. For example, inductive loads, like motors and solenoids, generate back EMF when switched off, but the EL2809 is designed to manage this energy, preventing potential damage and ensuring reliable operation.

Q: What protection features does the EL2809 offer for industrial use?

A: The EL2809 is equipped with multiple protection features to enhance durability and prevent damage. Each of its 16 output channels includes short-circuit protection, allowing it to handle current surges without harm if a short circuit occurs. Additionally, it has reverse voltage protection on each channel, preventing damage from accidental reverse wiring or voltage spikes. These features help to reduce downtime and repair costs in industrial applications.

Q: What is the output current capacity for each channel of the EL2809?

A: Each of the 16 channels of the EL2809 terminal can deliver a maximum output current of 0.5 A. Importantly, this output is short-circuit-proof, meaning that in the event of a short circuit, the terminal can withstand the surge without damage. The short-circuit protection further enhances reliability, making the EL2809 suitable for high-demand applications where equipment must be robust and resilient.

Q: How does the EL2809 ensure fast switching times in applications?

A: The EL2809 offers rapid response times, with a typical turn-on time of 60 µs and a turn-off time of 300 µs. These fast switching times enable the terminal to respond quickly to control signals, making it suitable for dynamic and precise control tasks in automated processes. This feature ensures that industrial applications requiring high-speed responses can be executed efficiently and accurately.
