Balluff BNI-PBS-502-000-Z001 Active Splitter Module

Balluff BNI PBS-502-000-Z001 is an active splitter module designed for Profibus networks, configured to bring 16 inputs and four IO-Link auxiliary interfaces into a compact ballast-style unit, all housed in a zinc primary enclosure and weighing about 1.36 kg. Also cataloged as the BNI000E, this device is described in product records as an Active Splitter with Profibus compatibility and auxiliary IO-Link channels, and it is noted as discontinued by the manufacturer. The module occupies a position in Balluff’s BNI family as a network interface splitter that supports IO-Link connectivity while distributing Profibus signals, providing a way to extend sensing and control capability within legacy automation architectures without requiring a new master network device. Key characteristics verified in distributor listings include 16 inputs and 4 IO-Link interfaces paired with a zinc housing, underscoring its rugged industrial design for factory environments. As a legacy Balluff part, the BNI PBS-502-000-Z001 remains of interest primarily to teams maintaining older systems or seeking compatible components from Balluff’s historical lineup, particularly where Profibus wiring and IO-Link expansion are already in place.
