solutions consist of a wide range of products. These products include TwinCAT automation software, Bus Terminals, and Lightbus systems, among others. They believe in strict compliance with quality standards, and ensuring the best customer service is something they highly value. Today, Beckhoff operates around the globe and through a network of partnerships and subsidiaries, has spread its network in almost 75 countries. Their entire product range is very economical but is not compromised in durability and performance parameters.\u003cbr\u003e\u003cbr\u003eThe EL6021 is an EtherCAT terminal produced by Beckhoff. The EL6021 has robust electronics and a solidly built outer housing. Due to these features, it can withstand extreme temperatures and very high humidity conditions. The system’s performance remains uncompromised in a temperature range of -25 to 60ᵒ C (for storage: -40 to +85 degrees Celsius). It can be interfaced with RS422\/485 interfaces. The system has a line impedance of 120 ohms and comes with an approx. 1000 m cable that is extremely handy when a long-distance operation is required.\u003cbr\u003e\u003cbr\u003eFull and half-duplex channels are provided for transferring data and the default data transfer rate is 9600 baud. Since Beckhoff’s products are designed for operating in all kinds of environments, which include very harsh conditions, the EL6021 comes with a design that conforms to the international protection IP20 class standards. IP 20 ensures that the enclosure is protected against solid objects up to 12 mm in diameter. The system is very lightweight and has a mass of just 55 g. Overall, the EL6021 is suitable for a variety of applications owing to its flexibility and high functionality.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturer information\u003cbr\u003e\u003c\/strong\u003e\u003cstrong\u003eBeckhoff\u003c\/strong\u003e Automation is a German manufacturer of open automation systems, including industrial PCs, I\/O and fieldbus components, drive technology, automation software, and hardware for machine vision.
