Product Description:
Beckhoff manufactures the IL2302-B520 coupler box as part of its IL Coupler Box Units series. This component serves as a remote I/O node that translates discrete machine signals into bus data for higher-level controllers in industrial automation. Installed close to sensors and actuators, it reduces cabinet wiring by combining power distribution and fieldbus communication in a compact, molded housing suited for assembly lines, packaging stations, and conveyor frames.
The module operates with a control voltage of 24 VDC, a level commonly used for industrial low-voltage logic. The shared control current is limited to 0.5 A, so supply planning must consider simultaneous load conditions. The unit has 4 digital inputs with opto-coupled channels for status feedback. It also provides 4 digital outputs for actuators such as valves or indicator lamps. Communication to the host PLC occurs through the DeviceNet fieldbus protocol, enabling cyclic data exchange and diagnostic services. Because the hardware contains no local CPU, the coupler is not programmable and relies entirely on the central controller for logic execution.
The physical design supports reliable installation in factory environments. An internal barrier provides fieldbus isolation that separates the DeviceNet electronics from the sensor supply. Downstream power and bus daisy-chaining are carried by a M8, 4-pin downstream connector, while sensor lines lock into a M12 bolted signal connection for vibration-resistant terminations. The PA6 thermoplastic housing is overmolded with a polyurethane casting compound that seals the CuZn gold-plated contacts against moisture and dust. Two M3 threaded mounting holes secure the box, and an identical M8, 4-pin receptacle brings in 24 V supply from the previous node. Operation is specified from 0 °C to 55 °C, allowing placement on equipment frames without additional heating or cooling measures.
