ABB DRA02 Card Rack: Industrial Control Module for Efficient Process Automation

ABB DRA02 Card Rack: Industrial Control Module for Efficient Process Automation

Product Overview

The ABB DRA02 card rack is a key and versatile component in industrial automation. Precision-engineered, it is the foundation for a reliable and efficient control system. Designed for seamless integration into a wide range of industrial devices, the card rack facilitates the connection and operation of multiple input/output (I/O) modules. It plays a key role in enabling smooth data transmission and control signal propagation, which is essential for the accurate and timely operation of industrial processes. Whether in a large manufacturing plant or a complex industrial facility, the DRA02 card rack acts as a central hub, ensuring that all connected components work together for optimal process automation.

Brand Background

ABB is a globally recognised technology leader with a history spanning more than 130 years. 1988 saw the merger of the Swedish company ASEA with the Swiss company BBC Brown Boveri to form ABB, headquartered in Zurich, Switzerland. with operations in more than 100 countries and around 110,000 employees, ABB has established itself as a key player in a wide range of industries.

ABB is at the forefront of innovation in industrial automation. It continues to develop advanced products and solutions based on its extensive expertise in electrical, robotics, automation and motion control. The company's investment in research and development drives cutting-edge technologies that increase productivity, improve efficiency and contribute to the sustainability of industrial operations. the DRA02 card rack exemplifies ABB's long-standing reputation for quality, reliability and technical excellence.

Technical specifications

Physical dimensions: The dimensions are 130 x 100 x 190 mm (H x W x D, some sources indicate a height of 250 mm, a width of 40 mm and a depth of 200 mm, the first set of data, which is more detailed and possibly more accurate, is preferred for consistency). This compact size makes it easy to install even in industrial environments where space is limited.

Weight: The card rack weighs approximately 5.0kg, making it easy to install and transport.

Input Voltage: Compatible with 24V DC power supplies, the DRA02 provides a stable and reliable power input to the connected modules.

Operating Temperature Range: The DRA02 can operate over a wide temperature range of - 20°C to + 70°C (+ 60°C in some sources, a wider range is used here to cover more information). This makes it suitable for a wide range of industrial environments, including harsh locations.

Communication interfaces: Equipped with Ethernet/LP interfaces (some literature also mentions RS-485 interfaces, both are listed here for completeness). These interfaces enable seamless data communication between the card rack, connected I/O modules and other components in the industrial automation network.

Number of slots: The card rack has 20 slots (some sources state that it can support up to 12 I/O modules, assuming that the 20 slots can accommodate different combinations of modules). This provides a high degree of flexibility in configuring the system for specific industrial needs.

Environmental ratings: Environmental ratings of IP20 (protection against solid objects larger than 12 mm), IP65 (protection against dust and water sprays), and NEMA 12 (for indoor use, protection against dust, drips, splashes, and oil).

Certifications: The DRA02 card racks are CE, UL and FCC certified. These certifications ensure that the product meets international safety, EMC and quality standards.

Performance Advantages

High compatibility: The DRA02 is compatible with a wide range of ABB and third-party I/O modules. This compatibility enables industrial users to select the most appropriate module for a specific application, whether it is for measuring analogue signals, controlling digital outputs, or handling complex communication protocols. It provides an open solution so that users are not limited to a single brand's ecosystem and are able to build a customised automation system that best suits their needs.

Reliable mounting platform: Manufactured from high-quality, corrosion-resistant steel, the card rack provides a safe and stable mounting platform for I/O modules. This is critical in industrial environments where vibration, shock and corrosive chemicals are present. The robust construction ensures that the modules are securely mounted, reducing the risk of connection failures and system malfunctions, thus increasing the overall reliability of the automation system.

Flexible configuration: thanks to a large number of slots, the card rack can be configured according to the exact needs of the industrial process. Whether it's a small operation requiring a handful of I/O modules or a large industrial plant with complex control requirements, the DRA02 can be easily adapted. This flexibility not only saves costs by utilising existing modules, but also enables future expansion as business grows or industrial processes evolve.

Efficient data transfer: Thanks to a wide range of communication interfaces such as Ethernet, RS-485 and LP, the DRA02 card rack enables fast and accurate data transfer between the different components of an automation network. This is essential for real-time monitoring and control of industrial processes. For example, on a production line, sensors connected to the I/O modules can send data to a central control unit via the card rack's communication interfaces, allowing production parameters to be adjusted immediately to ensure optimum product quality and productivity.
