IL2302-B528-0000

The Beckhoff IL2302-B528-0000 is a compact I/O coupler box module in the IL Coupler Box Units series designed for industrial automation applications requiring reliable digital signal distribution. This device integrates four digital inputs and four digital outputs into a single housing, combining high-density connectivity with a minimal footprint. Featuring M12 screw-type connectors for both feed and downstream lines, it provides robust electrical connections in demanding factory environments. The module operates under EN 61131-2 standards and supports a rated load voltage of 24 V DC, ensuring compatibility with a wide range of control systems. Manufactured by Beckhoff, it delivers a balance of performance, durability, and ease of installation.

The IL2302-B528-0000’s technical specifications reflect its industrial-grade design. It supports 4 inputs + 4 outputs over M12, screw type connections, with a Rated Load Voltage of 24 V DC (-15%/+20%) and Auxiliary Power Current of typ. 20 mA. Input conditioning is provided by a 3.0 ms input filter, while signal thresholds are defined at -3…+5 V for logical "0" and 11…30 V; 6 mA for logical "1" in accordance with EN 61131-2, type 2. Outputs are each short-circuit proof, rated at 0.5 A per channel with a typical Short-Circuit Current of 1.5 A. Downstream power pass-through is achieved via a 1×M8 female 4-pin (downstream) connection, and upstream power is supplied through a 1×M8 male 4-pin (feed) connector. A sensor supply rail delivers up to 0.5 A protected against short-circuit conditions.

Operational performance of the IL2302-B528-0000 emphasizes reliability and resilience in industrial settings. Its PA6 polyamide housing measures 30 mm × 210 mm × 26.5 mm and features IP65/66/67 protection against dust, water, and oil ingress. The module withstands operating temperatures from 0…+55 °C and storage temperatures from -25…+85 °C, while vibration and shock resistance ensure consistent signal integrity. Electromagnetic compatibility is certified to EN 61000-6-2 immunity and EN 61000-6-4 emissions standards. DeviceNet communication is supported with automatic baud rate detection up to 500 kbaud, enabling seamless integration into networked control systems.

System integration is streamlined through standard M12 and M8 connectors, two fixing holes for M3 screws, and compatibility with Beckhoff bus couplers and fieldbus masters. The IL2302-B528-0000’s support for DeviceNET makes it an ideal choice for decentralized I/O distribution in packaging machinery, conveyor controls, and discrete manufacturing lines. Its combination of standardized signaling, integrated power distribution, and compact design addresses the needs of modern industrial automation applications where space, reliability, and performance are paramount.
