Product Description:
The IP2302-B528-0000 is a compact digital I/O module produced by Beckhoff for its IP Compact Box Units series. Housed in a sealed field enclosure, the unit brings sixteen discrete lines directly to a machine chassis and maps them to a controller over a single bus cable. This design lets an automation system collect sensor states and drive actuators at the installation point, reducing cabinet wiring and simplifying decentralized layouts common in conveyors, packaging machines, and assembly stations.
The module communicates through a DeviceNet node that already contains a tee connector, so it can be inserted anywhere along the trunk without additional fittings. All channels share a rated load of 24 VDC, and the process image occupies exactly 4 inputs and 4 outputs in the PLC memory. Each output can source up to 0.5 A per channel, while each input draws only 6 mA, allowing tight grouping on common supply rails. Load circuits are protected by an internal limit of 20 mA per input and by per-channel sensor supply paths that match the 0.5 A capacity of the outputs.
A separate M8 power feed connector delivers the field voltage, and the module passes that voltage to downstream devices through an identical M8 socket, maintaining daisy-chain power distribution without extra terminal blocks. Signal quality is maintained with a debouncing filter of 3.0 ms, and a short-circuit threshold of 1.5 A disables an affected channel until the fault clears. Galvanic isolation between the control and fieldbus circuits prevents back-feed from inductive loads, and all inputs conform to EN 61131-2 Type 2, ensuring consistent switching levels across equipment from different vendors. Threaded M12 connectors provide a vibration-resistant path for the field conductors, while a four-pin M8 socket on the opposite end supports downstream bus expansion without changing node addresses.
