Product Description

Beckhoff EtherCAT terminal EL3681-0030 is designed to operate with a supply voltage of 300 V AC/DC and can be used for monitoring of high voltage power supply and electrical appliances. Another of its main characteristics is the current range up to 10 A at the present time, which makes it possible to use it in low-current and high-current devices. The EL3681-0030 has a plus sign resolution of 18 bits This means that the signal accuracy is exceptional and signal is differentiated with high granularity; small changes in voltage or current are easily detected.

Besides the accuracy, the EL3681-0030 is designed for reliability and safety from overvoltage and overcurrent. This one has an isolation voltage of 1500 V, which ensures the system is shielded against electrical interferences. One of its chief strengths is in the ability to isolate from the input when this capability is most needed; for example, where noise or high voltage is present. The measurement uncertainty of the terminal at 40°C is as low as 0.01%, further increasing dependability in critical data acquisition applications. The EL3681-0030 is also equipped with spring loaded compression on all the connections it has to make to the network to ensure that the connection is firm and reliable. This has the benefit of increasing reliability of the connecting systems, in case stability of connection and lack of data loss is important. The terminal itself has a lightweight of approximately 50 grams meaning it can be easily integrated into large EtherCAT systems without the addition of size or complications.

In addition, the EL3681-0030 carries the CE, UL, and ATEX certification indicating that it meets requirements of most countries. This certification makes it safe for use in explosive areas or areas with certain norms for working environment such as chemical, refineries, and energy production.
