STBNDP2212 by Schneider Electric | Modicon STB NIM Module

Product Description – Schneider STBNDP2212 Network Interface Module

The Schneider STBNDP2212 is a high-performance network interface module (NIM) within the Modicon Advantys STB distributed I/O range. It functions as the communication head of an STB island, bridging distributed I/O modules with external fieldbus or Ethernet networks. Moreover, its compact DIN-rail design allows seamless integration into control panels, saving valuable space. Therefore, it is ideal for industrial automation, process control, and machine monitoring applications requiring reliable communication and precise data exchange.

This module supports up to 125 slaves, one primary, and six extension segments, providing flexible connectivity in complex automation networks. In addition, it offers built-in diagnostics, including LED indicators and a web server for real-time monitoring, helping technicians quickly identify and resolve communication issues. Its dual RJ45 Ethernet ports allow daisy-chain or ring topologies, ensuring robust and scalable network design.
