Product Description:

The Beckhoff EL1004 is an EtherCAT terminal designed to connect various devices related to automation systems. One of its key features is its connection technology, which includes a 2-wire setup. This means that the terminal connects to devices using two wires, making it simple and efficient to integrate different control systems. The 2-wire connection minimizes wiring complexity and costs, providing a reliable connection while minimizing installation time. The 2-wire technology is commonly used in various industrial devices, offering a robust and straightforward solution for connecting units to different automation systems. This setup allows for smooth and flexible integration into existing setups, ensuring high compatibility and ease of use.

The EL1004 does not have distributed clocks. Distributed clocks are often used in EtherCAT networks to synchronize communication across multiple devices in real time. However, as the EL1004 does not require this feature, it can be used in systems where time synchronization between devices is not critical. This makes it a simpler and more cost-effective option for applications that do not demand precise timing control, such as basic input monitoring or control tasks.

The EL1004 terminal is made of four input channels that run under a nominal voltage of 24 VDC. These inputs work on the fixed voltage signals to determine the state of the systems. It can be used in any digital input-related operations. The terminal features 3 mA input current and has 3.0 ms of filtering time that ensures quick and stable operation management. This EL1004 interacts with most industrial control systems by using a two-wire system that makes it easy to use. It can be easily connected to different connectors as it has a simple wiring system, thus suitable for industrial use.
